ENCRYPTED TRANSMISSION/RECEPTION
(
R EQUIRES A FTER - MARKET E NCRYPTION M ODULE
)
 If the transceivers you (and others in your communi-
cation group) are using are equipped with an after-mar-
ket Encryption Module, the Encryption mode may be
activated by pressing the
[
ENCR
]
key. The “ ”
icon will become illuminated.
 To de-activate encryption, press the
[
ENCR
]
key again.
 If the signals of all the other stations in your communi-
cations group have a severely distorted or “scrambled”
sound, you may have accidentally de-activated your
transceiver’s encryption mode. Pressing the
[
ENCR
]
key may allow recovery. However, if only one station
in your communications group sounds distorted or
“scrambled,” it is possible that the encryption mode of
that transceiver may have been accidentally turned off.
Either the dispatcher or you may advise the other sta-
tion by switching your encryption off and calling the
other station in the non-encrypted mode. Remember
that your transmissions will be sent in a non-encrypted
format, and will thus not be secure; limit your discus-
sion to a brief advisory regarding the
[
ENCR
]
key on
the other station’s transceiver, then revert to encrypted
operation immediately by pressing the
[
ENCR
]
key
on your transceiver.
