Radio-wide Features
Locked Radio Option - The user can choose to have different radio controls locked while
in Fire Mode and is set by programming. If this option is enabled, the radio will lock the
front and side buttons. Additionally, the radio can be programmed to lock the Channel
Selector, Volume Knob, Front Only Keypad, and Toggle switch. No matter the keypad
lockout options programmed, in Fire Mode the subscriber will always allow the buttons
for Emergency, Comm Check, Evac Alert, and the button programmed to initiate Fire
Mode, as it will be used to cancel Fire Mode. The radio will not power down while in Fire
Mode. Fire Mode must manually be exited for power down to occur.

Out of Range - When programmed, the Fire Commander will send out a beacon at the
programmed beacon time interval. If the Fire Responder does not receive a carrier event,
with an RSSI above the OOR threshold, within its programmed OOR Inactivity Duration
time, it will go OOR to notify the user they are no longer in receiving range of the Fire
Commander radio.

with an RSSI above the OOR threshold, within its programmed OOR Inactivity Duration
time, it will go OOR to notify the user they are no longer in receiving range of the Fire
Commander radio.
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.

Note
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.

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.
