APCO P25 MODE OPERATION

D Registration to the OTAR system
➥ Push [Zone], then push [CH Up] or [CH Down], or rotate
[CH Up/Down], to select a channel in which the OTAR
function is enabled.
After selecting the channel, the transceiver automatically
attempts registration to the OTAR system by transmitting a
KMM 'Registration' command to KMF.
NOTE: There are 2 types of KMM— Standard and Packet.
If the pre-programmed KMM type is not matched to the
system to which the transceiver attempts to register with,
the registration attempt may fail. In that case, the trans-
ceiver's KMM type should be changed to another type. Ask
your dealer for details.
D Deregistration from the OTAR system
➥ Push [CH Up] or [CH Down], or rotate [CH Up/Down], to
exit the channel in which the OTAR function is enabled.
After exiting the channel, the transceiver automatically
attempts deregistration from the OTAR system by trans-
mitting a KMM 'Deregistration' command to KMF.

D Rekey request function
Normally, the encryption keys are managed and securely
changed by KMF over the air without receiving a Rekey
request.
But the transceiver can control KMF remotely by sending a
Rekey request to perform the rekey operation.
q Push and hold [Rekey] for 1 sec. to send a KMM 'Hello'
command to KMF for a Rekey request.
• "REQUEST REKE" appears.
w After receiving a Rekey request from the transceiver, KMF
performs the rekey operation.
e When the rekey operation is successful, "REQUEST
REKE" disappears.
• If the rekey operation fails, "FAILED" appears.
D Active Keyset selection
This function allows you to select the Active Keyset that is
stored in the transceiver.
The keyset structures a group of keys. By changing the
keyset, the group of keys will be automatically switched to
another group.
q Push [Keyset] to enter the keyset selection mode.
• The selected keyset name ("KEYSET1" or "KEYSET2")
appears.
w Push [CH Up] or [CH Down], or rotate [CH Up/Down], to
select a desired keyset.
e Push and hold [Keyset] for 1 sec. to set the selected keyset.
r Push [Keyset] to exit the keyset selection mode.
