TRANSMITTER UNIT

_____Test transmitter output (record and compare to factory test listed inside unit).

_____Test for amount of reflected power (record and compare to factory test).

_____Test Transmit radio frequency (should be .0005% of listed frequency).

_____Measure deviation of FM transmitted data signal (should be 3.5-4 kHz.)

BASE ANTENNA CONDITION

_____Inspect antenna for loose or corroded wiring and connectors.

_____Inspect outdoor connectors for proper silicone protection and wrapping.

_____Measure DC resistance of antenna and cable (should be open circuit).

_____Inspect antenna for solid mounting.

_____Inspect antenna for good earth ground.

_____Measure VSWR of antenna and cable. (See transmitter power above.)

VEHICLE ANTENNA CONDITION

_____Inspect antenna for loose or corroded wiring and loose connectors.

_____Measure DC resistance of antenna and cable (should be open circuit).

_____Inspect antenna for solid mounting.

_____Check that antenna is mounted on metal vehicle surface at least two feet from obstructions and/or other antennas.

_____Verify antenna mount is properly grounded to vehicle surface.

ALARM ENCODER UNIT (Tests should be performed in conjunction with mobile display.)

_____Operation of test signal (reception at mobile display)

_____Measure and adjust data frequency  (8.33 kHz ± 2%)

_____Send test alarm messages (per manual)

MOBILE GRAPHIC DISPLAY UNIT(S) (Perform some tests in conjunction with encoder unit.)

_____Audio quality of received signal (use earphone provided with system).

_____Operation next to encoder (requires test antenna and power supply).

_____Proper operation of front panel REC and INT lamps.

_____Measure and adjust data frequency  (8.33 kHz ± 2%)

_____Align radio receiver module (requires service monitor and special test set up).
