An Out of Range Beacon can be programmed for the Fire Commander in five second
intervals from 5 – 80 seconds. When programmed, the Fire Commander will send out a
beacon at the programmed interval. An Out of Range Indicator can be programmed for the
First Responder in five second intervals from 7 - 82 seconds. When programmed, if the
First Responder fails to receive a beacon from the Commander for the programmed
duration, the First Responder will emit an OOR tone and display “Out of Range” on the
display until a carrier event with an RSSI level above the OOR RSSI threshold is received.

The slight offset between timers is necessary to avoid the radio momentarily going out of
range and then back in range.

Communications Check can be programmed to any radio, but is intended for, and only
works with Fire Mode radios. Only radios that are optioned for Fire Ground First
Responder, and currently in Fire Responder mode, can issue a “Comm Check.” When
pressed, the responder will sound one of several tones to indicate the RSSI range the
Responder radio is currently in. This feature will only work on digital channels and can
only be programmed as a function button.

When the “Comm Check” button is pressed on a Responder radio, the Responder requests
the current RSSI level from the Commander radio. If in range, the Commander radio will
respond with the RSSI level. If the RSSI level is Excellent or Good, the Responder will
sound a Talk Permit Tone. If the RSSI level is Fair, the Responder radio will sound two
beeps. If the RSSI level is Poor or OOR, the Responder radio will sound four beeps.
Please refer to the Conventional RSSI Guide for a list of RSSI thresholds to use when
programming this feature.

This feature makes use of the P25 Signaling Retry Attempts and Retry Response Timer
settings defined for the radio. If the Comm Check retries to completion and the Responder
Out of Range Indicator feature is enabled, the radio will go Out of Range. If not enabled it
will display No Ack for two seconds.

Comm Check works in either simplex mode or through a repeater configured for data
repeat mode, both of which require a Responder and Commander radio. Currently the
EFJohnson infrastructure does not support the process of Comm Checks so a Commander
radio is required.

Any radio can program an Evac Alert button; however, only subscribers that are optioned
for Fire Ground Commander, and currently in Fire Commander Mode, can issue an Evac
