Tait Orca Portable (TOP) Encryption
Midian Encryption Programming and Service Manual
June 2006 © Tait Electronics Limited
The Midian TVS2 module supports OTAR programming of encryption
codes only. However, the TVS2 supports direct programming of all
programmable functions.
Refer to the following manuals for detailed programming instructions

Midian Programming instructions

Midian Encryption Module Programming section

of this
manual
Important Additional Information
Once encryption is enabled, set the function buttons to:
■
turn encryption ON and OFF
■
access
Code Change
mode (optional)
■
set the number of user-accessible codes (optional)
Economy mode is the factory default, but is not recommended
with encryption-enabled radios as it will cause loss of sync pulses.
This may result in failure to decode some encrypted calls after a
period of inactivity.
If radios have no display, ensure no other function (eg incoming selcall
or repeater talkaround) is programmed to utilise the orange LED, or
it will be too difficult to determine encryption status.
Note
When using a TOP radio as a programming transmitter, if an
encryption module is fitted, ensure the encryption function is
turned off.
Equipment setup and programming instructions are described in the Midian
Encryption Module Programming section
on page 18
. Refer also to
programming and service manuals with the Midian encryption module and
programmer.
Service Desk OTAR programming may be unsuccessful if:
■
the target radio is open during programming
■
the programming radio and the target radio are oriented differently eg
one laying down, one upright
■
one radio is set to High Power
