Conventional Mode Features
Both the Entering OOR and Exiting OOR Tones will be disabled to avoid excess tones 
from fringe areas where the radio is toggling in and out of coverage.
Tones are restored on power cycle.
5.13.5 EFJohnson System Automatic Registration
When used in a EFJohnson P25 conventional infrastructure radio system, an option on the 
radio can be programmed to provide additional identifying information to the system upon 
receipt of a dynamic data registration request. If the “EFJ Affiliation” option is enabled, 
the radio will transmit its current talkgroup to the system in addition to its unit ID during a 
dynamic data registration request. EFJohnson also supports conventional standardized IP 
data context activation registration without the EFJ affiliation enabled.
The radio will attempt a data registration on channel change. If the radio does not receive 
a registration response after the programmed number of retries it will display “Reg 
Failed”. If the radio is out of range and then returns to within range of a site where it had 
not yet registered, it will initiate another registration.
5.13.6 P25 Group Calls
P25 Group calls are placed by simply selecting the channel programmed for the desired 
group, monitoring the channel if required, and transmitting. When a P25 group call is 
received, the alias (or frequency) of the selected channel is displayed. The radio can be 
programmed so that the following are also displayed for 0.5-7.0 seconds or continuously 
during the call.
PTT ID - The unit ID of the radio placing the call is displayed.
P25 Talkgroup - The alias of the talkgroup on which the call is being received is 
displayed.
User Group ID - If the group ID of the call being received is included in a 
preprogrammed User Group ID list, the alias programmed in that list for that group is 
displayed.
Received Key ID - The Key ID (or the alias, if programmed) of the key used to decode 
the call is displayed.
P25 Talkgroup - The radio displays the number or alias of the talkgroup on which the 
call is being transmitted. This can be programmed to display for 0.5-7.0 seconds or 
infinitely.
