Before descending from cruise, set the controller to your target airport altitude. You can monitor the cabin altitude, differential pressure and cabin climb rate on the instruments next to the controller.
Above a cabin altitude of 8000ft, it can
endup in a abnormal low level of oxygen in your blood. If this happen you will feal a blackout and it's necessary to bring immediate the cabin altitude below 8000ft by descend or pressurise the cabin.
For lighted instruments switch on the INSTR switch on the side switch panel. On the same panel you can switch the DAY/NIGHT switch to NIGHT for dimming. The 5 round turn knobs on the panel now can be used to set your dimming level.
The IFD-s have their own dimming switch on the left upper side of the bezel. For
taxying use the RECO lights. For landing the LDG light.
