3.2 Hidden Function
1. Clearing Patient Data
(Available on version 1.28 and later)
Clearing the data of the RESmart CPAP and Auto-CPAP unit requires use of a hidden function. Caution: Once the data is cleared, there is no possibility of recovering erased data.
To clear all recorded data and restore the unit to initial factory default settings, enter the Patient Menu by depressing ramp for 3 seconds or more. Advance the menu using the “+” sign until you reach the date option. Manually change the date to reflect: Year = 2097, Month = 07, Day =01, Hour = 0, Minute =26.
Press On/Off button when “Hour” setting is displayed. It is not necessary to save the setting.
Important note: After data has been cleared, it will be necessary to
re-set the device, reviewing all patient and clinician settings (i.e. enabling iCode, correcting to current date, etc.).

2. Pressure calibration
(Available on version 1.20 and later)
Connect pressure meter to the gas outlet in the device, enter hidden datesetting, set ‘YYYY/MM/DD’=’2098/08/08’, press ‘On/Off’ when ‘Hour’ setting, thus pressure calibration starts. The device increases pressure to
20hPa(cmH2O), AD sampling data will appear on LCD. When LCD data displaying is stable, if pressure meter value is not 20, press ‘+/-’ button to adjust the pressure output. Until output pressure value is 20 and LCD displays stable, press ‘On/Off’ button to finish pressure calibration.
3. Debug mode
(Available on version 1.19 and later)
Enter hidden date setting, set ‘YYYY/MM/DD’=’2099/08/02(or 03)’, press ‘On/
Off’ when ‘Hour’ setting, thus debug #02 or #03 mode starts. The device can send real time data to computer via serial port. Only cutting off power supply can make device back to normal mode.
