OTAR is the over-the-air-rekeying from a KMF and must be enabled for the digital only channel using

Loader or a KVL device.
The KMF Configuration must include the RSI of the KMF and the appropriate Message Number Period.
To enable OTAR and request rekey:
1. Press the Menu button.
2. Navigate to the SECURITY menu.

ENABLED/DISABLED.
4. Scroll up or down to highlight OTAR REKEY and press the Group/Channel Select Knob to request
that the KMF update the keys in the radio. OTAR REKEY is only enabled if the radio has successfully
registered for data operations. If enabled via programming, the radio plays an audible confirmation
tone to indicate successful OTAR rekey.
5.20 P25 CONVENTIONAL FALLBACK
When P25 Conventional Fallback is enabled, a P25 trunking site responds to failures by allowing one or
more channels to operate as conventional repeaters. Terminals which are properly configured can then
communicate using the conventional P25 channel(s).
The radio provides an audible and visual indication when operating in P25 Conventional Fallback.
