To Initiate a BIT Test
Use the following procedure to initiate an interruptive BIT test from the transceiver's front panel. A BIT
test cannot be initiated while the transceiver is keyed. An interruptive BIT test cannot be initiated in
Mode 2 or Mode 3.
(1) From the Main screen, press the switch to
display the Control screen. Turn the switch
until BIT is highlighted. Press the switch.
(2) Ensure the BIT menu is displayed. Turn the
switch until BIT Initiate is highlighted. Press
the switch.
(3) During the test, which takes approximately
two seconds, the Testing screen is
displayed.
(4) On completion, and if the interruptive test was initiated from the front panel, one of the following
screens will be shown.
(5) Selecting OK takes the user back to the BIT
screen.
(6) Selecting OK takes the user back to the BIT
screen. The user can then scroll through the
screen to check out transceiver parameters
for failure.
During an interruptive BIT test, the transceiver radiates modulated carrier waves at the set power.
Users should therefore obtain the necessary authority before initiating a test.
If the test is to be carried out with the antenna disconnected, ensure a load is fitted to the
transceiver's Antenna (not Rx Antenna) connector.
In order to test the line input stages, an internally generated 1 kHz tone is injected into the line input
circuit. Any other audio present on the line input will cause the test to be inaccurate. Therefore the
transceiver must not be keyed during the test.
