August 2, 2018- FIRMWARE UPDATE NEEDED FOR SOME DEVICES – Fault Code 66 – Z1 Auto Firmware v2.1.0.5

This firmware change is for Z1 Auto CPAPs (black devices) with lot codes between A182602-A182901* which were manufactured between June 28, 2018 and July 25, 2018. You can find the date of manufacture and the lot codes on the back of the device.

This firmware version corrects an issue in Firmware v2.1.0.6 which causes an Error 66 message when connecting to Nitelog via Bluetooth and shuts off the device. This is easily corrected by power cycling the device by unplugging and replugging the power cord to the device. It does not harm the device. But if you want to use Nitelog, you must install Firmware v2.1.0.5.

*Affected lots A182602, A182603, A182604, A182605, A182701, A182801, A182802, A182803, A182804, A182901.

Fault/Reminder Codes (8)

When the Z1 is in stand by mode, the screen reads 0.0 in the pressure area. If the screen is not displaying 0.0 when turning your machine on, would indicate that it needs to be returned for repair. Please contact your provider, and they will advise you on what steps to take.

If the display screen shows your pressure, and the fan has not started blowing air within thirty seconds, then the blower has failed and the machine should be replaced.  Please contact your provider and they will advise you on what steps to take.

The Fail 1 code means that you are hitting the power button while the motor is still running. It will happen when you hit the middle button repeatedly.

A Fault 22 means that there is an SD card stuck in the SD port of your Z1 machine and needs to be removed from the device. Do not attempt to remove the SD card yourself.

A Fault 33 is a defect in the unit and will need to be returned through the provider you purchased it from. Please contact your provider and they will advise you on what steps to take.

A Fault 66 indicates your machine will need to be returned through the provider you purchased it from. Please contact your provider and they will advise you on what steps to take.

An Error 18.8 indicates that there is a defect with the display panel, and will need to be returned through the provider you purchased your machine from.  Please contact your provider and they will advise you on what steps to take.

The word REMINDER indicates there is an excessive air leak somewhere. If it is happening while you have your mask on your face, please disconnect all parts to the Z1 including your mask and tubing (battery from the PowerShell, PowerShell from the machine, and unplug it from the wall). Reassemble the parts to the Z1.

If the REMINDER reappears, the device will need to be returned.  Please contact the provider you purchased your machine from to assist you.

General Questions (16)

No, the data cannot be transferred from one device to another. Data on the Z1 will be stored for the usage on the actual unit itself.

The firmware upgrade posted on our website is for the black Z1 Auto only.

Please do not use this firmware upgrade on a white Z1 CPAP machine.

If you have an Auto and would like to upgrade your firmware, please visit the following link: https://breas.us/cpap-user-guides-and-software/

 

The Z1 must be returned to replace the silicone outlet tube.  Please contact the distributor you purchased your Z1 from, and let them know your unit needs to be returned to the manufacturer.

The PowerShell auxiliary plug is designed to work with 12v systems.  If the system drops below 12v the system may shut off.

The dim light is on a timer and should turn off after a few moments. Unfortunately, there is no way to change the timer on the backlight of the LCD screen.

When the Z1 is in stand by mode, the screen reads 0.0 in the pressure area. If the screen is not displaying 0.0 when turning your machine on, would indicate that it needs to be returned for repair. Please contact your provider, and they will advise you on what steps to take.

If the display screen shows your pressure, and the fan has not started blowing air within thirty seconds, then the blower has failed and the machine should be replaced.  Please contact your provider and they will advise you on what steps to take.

The minimum voltage you will need to charge your Z1 device is 12 volts.

It is an activated oxygen cleaning system that completely sanitizes your CPAP without any water or chemicals and kills 99.9% of all germs and bacteria in the hose and mask.  Please see the attached video on how to connect your Z1 device to the SoClean machine.

The Z1 runs on electricity from 100-240V which means you will not need a converter for international travel. You will only need a plug adapter to fit the right configuration for the country you are visiting.

Our tubing comes in two different lengths- 4 feet and 6 feet slim style. They are 15 mm in diameter. You can use standard tubing with the Z1, which is 19-22 mm diameter.

The most common cause of a pressure increasing, beyond what is necessary, is a leak in the system/mask. It may be a leak in the connections to the mask, or the hose.  Please check to make sure these connections fit tightly.

Another reason is an excessive leak at the mask.  Please make sure you have a proper seal between the mask and your face.

Check the connection of the tube adapter and the outlet tube (the rubber piece where the tube adapter connects to the machine). If the tube adapter is not properly seated in the outlet tube, the pressure sensor may not be getting the information it needs to regulate the pressure. Also check to make sure your outlet tube is not torn. If it is torn, the device will need to be returned to be repaired.

The last reason could be the Z1 may be sensing an obstruction, which reads as an apnea, and thus increasing the pressure.  This could be caused by congestion, or a mask system that has very low flow rate. If you have a mask with very low flow rate, such as some of the very small nasal pillow masks, you may want to try a mask with less restriction such as a nasal mask.  If none of the above are successful, please contact the provider you purchased your Z1 from.

HME's (Heat Moisture Exchangers) (5)

No, you are not at risk of rebreathing as long as your mask has an exhalation port and your device is turned on.

There are several variables that determine how long your HME will last. Your pressure setting, how often you use the HME, and how you store it.  It is recommended that the HME is stored in an airtight container/zip lock bag when not in use to help it last longer. The estimated time is 7-30 days depending upon the variables listed above.  If you feel it is not providing enough humidity, it is time to replace the HME.

To get more humidification, I would recommend getting a lubricating nasal spray, nasal gel, or an in-room humidifier at your residence or hotel.

The Heat Moisture Exchanger (HME) is a portable humidifier that provides humidification during therapy.  The HME works by capturing moisture into the blue sponge as you exhale, and when you breath in, it delivers the humidity back to you.

The HME connects between your mask and your tube. The HME is not as effective unless it is connected right at the mask. For those who have an extension tube as part of their mask, the HME is less effective because the humidity you are exhaling will not reach the HME. Please see the attached picture.

Nitelog App (4)

Please follow the steps below to connect to the Nitelog App.

  • Nitelog only works with the Z1 Auto. Verify that they have the Auto (black) and not the CPAP (white)
  • Make sure your Bluetooth is turned on in your phone.
  • Download Nitelog from the app store onto an iOS (Apple) mobile device (iPhone or IPad), or Google Play store for Android phone or tablet. (Nitelog must be one word).
  • Fill in your name under the Legal Disclaimer form, if you want your name on the compliance reports so you can send them to your healthcare provider. If not, you can remain anonymous.
  • Read the document (software end-user license agreement) and click on “I agree” if you accept.
  • Open the application, and press on the plus sign (+) in the top left-hand corner.
  • An option will appear that reads Z1 with four digits after it (example: Z1 1234). The 4 digits are the last 4 digits of the (S/N) serial number shown on the back of the unit.
  • Click on the white bar that shows “Z1 XXXX” (last 4 digits of serial #) to the left of the word “disconnect” to sync the device. The disconnect button is used if you no longer want to pair with the device after connecting.
  • It will then ask you to “enter your password”. Click on update password and enter any 4–8 digit number.  This is so others cannot pair with your device and see your data.  If you forget your password, click on update password to reset.
  • After saving the password, there will be a 20 second countdown on your phone and Z1. Hold down the middle power button of the Z1 during the 20 second countdown to pair the Z1 and phone.
  • A message will appear asking if you would like to change the time to your local time zone. Make sure you set your time zone to ensure the data is accurately recorded.

In the top right hand corner of the Nitelog app you will see a settings icon (looks like a tire or gear) click on it. Options will appear with different settings.

Click on Chart Settings and adjust the Usual Sleep Time to the time you normaly go to bed. (Bump up the “hours of sleep” and “goal” to their highest limit)

Under compliance settings make sure the “compliance range in months” is set to 12 months (set the “compliance day window” / “required days” and “minimum hours usage per day” to the max settings by using the plus sign).

Your viewing window may be set incorrectly. To fix this, go into chart settings by using the gear icon in the top right corner of the main Nitelog screen. Change your usual sleep time to the time you normally go to sleep and change the hours of sleep to 12. You should now be able to view your data for the night selected.

On the last day of each month, the Z1 Auto only ‘logs’ the time used between the start of usage and midnight. It does not report any time between midnight, and morning of the first morning of the month. Is there a fix to this problem?

Your viewing window may be set incorrectly. In order to fix this, go into chart settings by using the gear button in the top right corner of the main Nitelog screen. Change your usual sleep time to the time you went to sleep and change the hours of sleep to 12. You should now be able to view your data for the night selected.

PowerShell and Battery Questions (3)

No, you cannot run your Z1 on a DC mobile adapter however, it can be used to charge the PowerShell. We cannot guarantee the mobile adapter will function with all cars, as battery voltage isn’t uniform.

Once the battery is fully charged, please disconnect your Z1 machine from your PowerShell and remove the battery from the PowerShell, or it will slowly drain the battery over the course of 2-3 days.

Make sure you hear a clicking noise when inserting the Z1 into the PowerShell.

If it is still not charging disconnect the Z1, battery, and power supply and reconnect.

Proceed to recharge your unit again for 10-12 hours. If it is still not holding a charge it will need to be sent in for a return by the provider you purchased your unit from.

Please keep the following information in mind after charging your Power Shell:

  • Disconnect the battery from the PowerShell after a full charge to prevent the battery from slowly draining within a 2-3 day period.
  • The battery needs to be charged for 10-12 hours to ensure a full charge.
  • The bars of battery life on the LCD screen need to be full, and not blinking.
  • The PowerShell will not hold a charge while using the Z1 for treatment, it must be charged separately.
  • The PowerShell cannot be charged while using the Z1 for treatment.
Purchase Questions (9)

We do not bill insurance. We suggest that you contact your insurance provider to inquire about reimbursement for your CPAP device and use HCPCS code E0601.

Yes, the HCPCS code is E0601.  If you are submitting for reimbursement use the E0601 code. The PowerShell battery system does not have a HCPCS code.

Please follow the link to find the nearest distributor in your area or call us at 855-436-8724.

https://breas.us/where-to-buy-a-cpap/find-a-medical-equipment-supplier/

The Z1 system includes: Z1 device, tube adapter, 4 ft. slim-style tube, power supply cord, custom USB cable, HME (travel humidifier), 2 air filters, the User Manual, and the Getting Started Guide. It does not come with a mask. Most people use the mask they are already comfortable with.

The main difference between BiPAP and CPAP machines is that BiPAP machines have two pressure settings: the prescribed pressure for inhalation (ipap), and a lower pressure for exhalation (epap). The dual settings allow the patient to get more air in and out of their lungs.

A fixed pressure CPAP device provides a fixed therapeutic pressure. An Auto adjusting CPAP provides a variable therapeutic pressure throughout the resting period. The benefit of an Auto adjusting machine is that it changes with your varying pressure needs resulting in a 40% reduction in mean pressure.

The warranty on the Z1 is three years from the date the patient purchased the unit from the reseller, with their receipt.  If the patient does not have a receipt, the warranty period starts from the time the DME purchased the device plus a two-month grace period.

Please contact us at 855-436-8724, and we would be happy to discuss why the Z1 is, or is not, an appropriate choice for you.

No, a BiPAP prescription is specific to a BIPAP machine and cannot be used for a CPAP machine and vice versa. You will need to discuss this with your doctor if you would like to purchase a CPAP device.

Q-Tube (1)

The Q-tube is an inline CPAP muffler that helps mitigate the wind noise one may hear in the mask.

Travel Questions (6)

Yes, the Z1 CPAP is FAA compliant for use on airplanes. I have attached the FAA compliance letter to present to the airline if need be.

No, we currently do not sell solar chargers.  Additionally, we are not aware of a solar charger that works with our device.

The PowerShell auxiliary plug is designed to work with 12v systems.  If the system drops below 12v the system may shut off.

The minimum voltage you will need to charge your Z1 device is 12 volts.

The Z1 runs on electricity from 100-240V which means you will not need a converter for international travel. You will only need a plug adapter to fit the right configuration for the country you are visiting.

Our units have been tested for up to 8,000 feet. We cannot guarantee the operation of the device above 8,000 feet.
