To unlock the radio:
1. Enter your 8 digit Master Reset PIN.
2. Press Confirm or the Select/Send key.
If you enter the Master Rest PIN incorrectly, you need to wait at least 5 seconds before attempting to
enter the PIN again.
If the Master Reset PIN is successful, the radio reverts back to the last known PIN.
If you radio is customised to allow the PIN to be changed, select Options > Settings > PIN
Change.
End-to-End Encryption
If your radio shows the Secure Comms icon when it is idle, the selected talkgroup is customised
for End-to-End Encryption (E2EE). In other words, calls you make by pressing PTT are end-to-
end encrypted.
It is not possible to accidentally make a non end-to-end encrypted call. Every talkgroup or individual
subscriber that can be exempt from End-to-End Encryption must be explicitly customised into the
radio.
End-to-End Encryption is designed to provide maximum security for voice and SDS
communications, whether operating in Direct Mode or Trunked Mode, irrespective of the security
level provided by the network. Depending on customisation, the radio may change the End-to-End
Encryption status when the selected network is changed. It may also provide a selection of
talkgroups on other networks. If a talkgroup is selected that does not belong to the current network,
your radio will change network accordingly.
A radio that supports End-to-End Encryption may nevertheless be required to make calls that are not
end-to-end encrypted. For example, calls to certain talkgroups and individual subscribers may be
customised to be exempt from End-to-End Encryption. All telephone calls are also not end-to-end
encrypted.
When dialling, a separate Secure Comms icon is displayed in the dial box if the call or SDS will be
End-to-End encrypted. During voice calls only (not SDS calls) your radio may allow you to toggle
End-to-End Encryption on/off with a soft key.
When you are in a voice call, the Secure Comms icon indicates whether End-to-End Encryption is
operational. When the radio participates in a call that is not end-to-end encrypted, a periodic non
intrusive audible alert is generated (if customised).
When you receive an SDS (text) message or picture messages, if you see the Secure Comms icon
in the message details that the message was end-to-end encrypted.
If the message ‘Security Check Fail’ is displayed while making or receiving calls, it indicates that the
radio has not been customised properly. In such cases, please contact technical support in your
organisation.
