FIGURE 2- -6 CRIMPING PRESSURE ADJUSTMENT
2.4 POST INSTALLATION CHECKS
An operational performance flight test is recommended after the installation is completed to insure
satisfactory performance of the equipment in its normal environment. Check all aircraft control
movements to be sure no electrical cables interfere with their operation.
communications transceiver, maintain an appropriate altitude and contact a ground station facility
at a range of at least 50 nautical miles. Then contact a ground station close in. Pull the volume
control out to defeat the automatic squelch feature and listen for any unusual electrical noise which
would reduce the comm receiver sensitivity by increasing the squelch threshold. If possible, verify
the communications capability on both the high and low end of the VHF comm band.
As an added precaution before the flight, check the antenna. VSWR
should be checked with an in--line type wattmeter inserted in the
coaxial transmission line between the transceiver and the antenna.
Any problem with the antenna installation will most likely be seen as a
high reflected power. A VSWR of 3:1 will result in a 25% loss of
power.
The brightness of the display can be set for the most pleasing
intensity by placing the unit in Dimmer Adjust mode during low light
level conditions. See
Adjust mode operating instructions.
