To Initiate a BIT Test
Use the following procedure to initiate an interruptive BIT test from the transmitter front panel. A BIT test
cannot be initiated while the transmitter is keyed. After a BIT test has been run, the BIT screen is
displayed (see
AM-Voice and AM-MSK BIT Screen on page 25
). 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

During an interruptive BIT test, the transmitter 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
transmitter'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
transmitter must not be keyed during the test.
