(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.
On completion, and if the interruptive test was initiated from the front panel, one of the following screens
will be shown.
(4) Selecting OK takes the user back to the BIT
screen.

(5) 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.
