9. P25 CONVENTIONAL CONTROL SIGNALLING (SBC) (Digital Base Mode Only)
Please note: SBC functions are selectable in the Programming Software.
The Base Tech III has been developed to work with any P25 radio under the TIA
specifications. However not all subscriber radios have the capability of these
functions.
9.1 EMERGENCY MODE TX-
Press and hold the F key to send an EMERGENCY call. (Note: The radio will
transmit on the programmed EMERGENCY channel not necessarily the channel
that appears on the display.)
Reboot the radio to clear the Emergency Alert.
EMERGENCY MODE RX-
To clear a received Emergency call, Press and release F twice.
Press F to enter the SBC mode.
Key functions after entering menu selection;
Press A for the next and B for the previous menu item.
C stops transmission (The radio transmits the SBC 4 times until acknowledged.)
D moves the cursor between items within the selection.
* deletes the last digit.
# transmits the selected SBC mode.
Please Note: When the radio is in SBC mode, it can receive Group calls, All Call and
Individual calls but no source address (caller unit ID), is displayed.
Emergency calls can be received when in SBC mode but the radio gives priority to
Radio Inhibit. Both Emergency and Radio Inhibit are ignored when in SBC
transmitting mode.
The radio will revert to normal operation if no key is pressed for 10 seconds.
