The cryptographic keys stored in DES version
radios can also be zeroed using two (2) additional
methods. Removing the battery pack for several
minutes (typically three), or disassembling the radio
will zero all of the cryptographic keys stored in a DES
version radio.
RECEIVING A MESSAGE
1.
Slide the ON/OFF SWITCH on the battery
pack to the on position. The radio will initiate
and complete the power-up self-test and
beep if the power-up alert tone is pro-
grammed on.
2.
Select model - Select the desired channel.
Scan and System models - Select the de-
sired operating mode, channel, and/or
Channel Guard. See the MODE/CHAN-
NEL/CG SELECTION for details.
3.
Press the MONITOR BUTTON briefly to
disable squelch and adjust the VOLUME
CONTROL for the approximate desired
speaker audio level. Pressing the MONI-
TOR BUTTON may affect Channel Guard
and/or Type 99 tone operation if pro-
grammed for the selected channel.
4.
If the selected channel is programmed for
private operation, the radio will automat-
ically switch between clear or private re-
ceive operation.
When an encrypted transmission is re-
ceived, the "PVT" status flag will flash, the
receiver will unsquelch, and the message
will be heard in the speaker. The selected
channel must be programmed for private
operation and the correct cryptographic key
must be loaded into the radio for this to
occur.
If a clear mode (non-encrypted) transmis-
sion is received, the receiver will unsquelch
and it will be heard in the speaker. However,
if the selected channel is programmed for
Channel Guard or Type 99 tone operation,
the receiver will not unsquelch unless the
correct CG or T99 tone is received.
5.
Adjust the volume as necessary.
