Equipment setup and programming instructions are described in the Transcrypt Programming
section on page 69 or the Midian Programming section on page

the encryption module. Refer also to programming and service manuals with your Transcrypt or
Midian encryption module and programmer.

Testing the Encryption Module
Equipment setup and testing instructions are described in the Transcrypt Programming section on
page 69 or the Midian Programming section on page
79, depending upon the origin of the
encryption module.
With encryption off:
Check normal power-up of the radio, with the normal display messages and confirmation
tones.
Check that receive and transmit audio are functioning, using a service instrument or another
radio on the same channel.
With encryption on:
Check that receive and transmit audio are functioning, using another T2000 or TOP radio
with the same encryption module, programmed with the same codes, on the same channel.
Where a code hopping module is fitted, confirm encryption is active by listening for the
initial sync burst on the receiving radio
Where a code inversion module is fitted, confirm encryption is active by pressing any
function key - the confidence tone will be a higher frequency than normal.
Check the Encryption User Interface features – status indicators, encryption settings etc.
(See the TOP Encryption User’s Guide information provided on page 37).
