6. TESTING PROCEDURES
6.0 GENERAL
The 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. The internal circuit and
antenna tests are periodically performed automatically
while the unit is in use.
6.1 POWER ON
Press and release the PWR switch. The unit will progress
through the power-up sequence; light all the LCD pixels,
test both antenna ports for connected antennas, and perform
a crystal cross check to verify the timing accuracy of the
speed processing circuitry.
The results of these tests will be displayed on the test
results screen before progressing to the main enforcement
screen. The results of the Internal Self Test will be “PASS”
if all internal tests are within tolerance. If any of the
internal tests fails, the specific test failure will be reported,
such as “CRYSTAL FAILURE”. The band of each
antenna connected to the unit will be displayed (K, KA,
NONE). The current setting of the audio and range levels
are also displayed on this tests results screen. As well, the
audio is unsqelched to allow the user to hear the audio
level.
