Checking The Installation
Verify the power and ground connections before applying aircraft power. Pin 15 on the G3 series Display is
aircraft ground and pin S is approximately +14V DC or +28V DC (See Drawing No. 1200-018).
For Model G3, pin 15 must be connected to the ground bus (airframe ground). When power is initially applied,
the GEM series Display will illuminate to full brightness.
Immediately upon power application the version number of the operating system software will appear in the G3
Display for approximately two seconds. After the version numbers extinguish, the G3 reverts to Monitor Mode
operation. Monitor Mode is the default power-on operating mode. EGT and CHT (and TIT) color-coded bar
graph columns indicate their respective cylinder temperatures, and supplementary values appear in cyan.
The G3 Display brightness level automatically adjusts to match the ambient light level.
The automatic dimming may be tested in bright ambient light by covering the entire face of the Display with the
palm of your hand for several seconds. The Display will dim and then brighten when your hand is removed.
In low ambient light, the auto-dimming feature may be tested by shining a flashlight on the display for several
seconds. It changes brightness slowly, in discrete steps, to prevent annoying flicker in response to rapid ambi-
ent light level changes.
After the tests described above have been performed, check for possible interference with existing avionics
by listening for audio interference on Com, Nav, DME, ADF, etc. Interference is uncommon, however, these
characteristics should be tested.
If interference is detected, remove power from the Display unit to check if it is the emitter of the interference.
If the GEM series Display is the interference source, re-route the wiring harnesses away from affected equip
-
ment.
