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. After a BIT test has been run, the BIT screen is
displayed (see
AM-Voice and AM-MSK BIT Screen on page 30 ). 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.

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 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.
