6. TESTING PROCEDURES
6.0.
Overview
The internal test and tuning fork tests explained below
should be conducted at the beginning and end of each patrol
shift to ensure the accuracy and functionality of the unit.
The results of these tests may be recorded in a radar log,
similar to the log found at the end of this manual.
6.1.
Power On
Momentarily depress the POWER switch. The unit will
display all LED display segments (888) and turn on all
lamps and indicators on the front panel. After
approximately 1 second, the unit will perform several
internal tests and a crystal cross check to verify the accuracy
of the speed processing circuitry.
If these pass successfully, the unit will display "PAS" in the
TARGET display (stationary operation) or both the
TARGET and PATROL displays if the unit is in the moving
mode of operation. This will remain for approximately 1
second. The TARGET display will then indicate "Aud" and
the PATROL speed window will display the audio volume
level last selected (0 - 9). A short tone at this volume level
will be heard in the speaker.
One second later, "rnG" will be displayed in the TARGET
window and the PATROL window will display the current
range level (1 - 6). After another second, the displays will
clear and the unit will be operational in the same mode that
it was in when the unit was shut off.
