To Initiate a BIT Test
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)
After the test, either a Pass or Fail screen
is displayed. Selecting OK takes the user
back to the BIT screen.
(5)
If fail is displayed, scroll through the screen
to check the cause of the failure.
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.
