An internal circuit test can be performed at any time by pressing the 
SELF TEST key. This  performs a diagnostic check on the 
display/counting unit, the selected antenna, and antenna cable.  Since 
only the selected antenna is tested, it is necessary to perform this test 
twice --  once with the front antenna selected, and once with the rear 
antenna selected. 

The display/counting unit will first complete a processor check, 
memory check, and crystal accuracy check; followed by the display 
of speeds of 10, 35, and 65 (Figures 37, 38, and 39); and ending with 
a display of the display/counting unit internal operating temperature 
in degrees Fahrenheit (e.g., 110 

°F) (if the unit has been ordered in 

kilometers, the temperature will be displayed in Celsius (e.g., 35 
°C)), and input battery voltage (e.g., bAt 13.8) (Fig 40 and Fig 41, 
respectively). 

A comprehensive test is also performed on the selected antenna by 
the display/counting unit to ensure the integrity of the selected 
antenna cable and antenna electronics.  After all the tests are 
completed,  PASS (Fig 42) along with a 4-beep “happy” tone 
indicate successful test completion.  FAIL (Fig 43) along with a 15-
beep tone indicates a failed self-test. 

Note: We recommend that the internal circuit test be performed on 
each antenna.

An automatic self-test (indicated by a 4-beep “happy” tone) is performed every 10 minutes while S 

is transmitting.  

Switching antenna will reset the 10 minute timer.
