Setting the clock

The time on xPAP machines are usually set at the factory. Some can be reset to the local time but others cannot. Then there is, in most locations, the twice a year time change. This wiki page will discuss if setting the clock is possible and how to do it.

CPAP clinician setup manuals can be obtained for most common CPAP machines by going to Apnea Board's CPAP Clinician Manual Page. For further assistance, patients can post questions on the Apnea Board Forum.

Respironics

The time and date for a Respironics xPAP is set at the factory and cannot be changed by the user. The time is set to the Coordinated Universal Time (UTC). See the External Links section below to find out how to determine the time difference for your location.

Resmed

ResMed xPAP time and date can be changed by the user. It involves accessing the "Clinician" section of the settings.

Instructions for A10 series machines:

(AirSense 10 and AirCurve 10 machines)

Always backup your data on the SD card before making changes!
Plug the machine in. The "dial" can be turned or pushed in the center. The button below the screen with the house icon is called the "home" button. To access the clinician menu, press the dial and the home buttons simultaneously for 3 seconds. The clinician menu will appear.

Note: If you have already been using the machine, you must wait more than an hour after you have gotten up and turned off the machine before you try to set the clock back an hour. Setting the time back too soon will confuse the machine since it has already recorded data for that time period. For best results wait until later in the afternoon or evening to change the clock setting.

Instructions for Airsense 11 Autoset Machines:

This is a new model and some features have been changed. There is no longer a clock adjustment in the settings. Instead the machine uses your time zone offset from GMT (UTC). Depending on what part of the world you live in your time zone offset will either be a negative or positive number (-6, +5, etc.). This setting is meant to be done prior to the first time you use the machine.
If you are unsure what your time zone offset is, check the following website: https://www.timeanddate.com/time/map/

WARNING: Changing the time zone in your machine will erase all patient data! Always make a backup of your SD card data prior to changing any settings!

To change your time zone settings:
