3.12 USER TRANSMIT CODE GUARD
When the radio is being programmed with transmit and receive frequencies for each channel, a
receive Code Guard value and a transmit Code Guard value can also be assigned to each
channel. On channels that do not have a default transmit Code Guard programmed, the user can
choose CxCSSs from a global UTXG Pick List containing 32 entries. To assign a UTXG for use
on a channel, all scanning functions (Channel Scan, Group Scan, and Priority Scan) must be
turned OFF.
The user selects a channel and then uses the keypad to enter a number from
1 to 32. When UTXG is active, the second line of the display will show the
number of the selected list entry (TONE – XX). Once a UTXG is assigned to
a particular channel, it will be stored and used with that channel whenever
the channel is selected. Repeater Talk Around operation will use the pre-
programmed RX CxCSS.
The UTXG Pick List can be viewed by pressing [FCN] [1]. The display will
show:
TONE – 01 or TONE – 01
XXX.X DXXX
Press [PRI] to increment through the list or key in a number. Press [ENT] to
exit the list viewer. (This feature is for viewing the list only. Pressing [ENT]
when a list item is displayed does NOT associate the UTXG with the selected
channel.)
Programming of the list (if programming is not locked out by PC software)
can be accomplished as follows:
1. While viewing the list, press and hold the [FCN] key until the ‘PROG’
annunciator lights.
2. Press [CLR] and then enter the new CxCSS. Press [ENT] to store the
new value and return to the list viewer.
3.13 OTHER OPERATIONAL FEATURES
The BK Radio GPH-CMD Series is based on a microprocessor core that allows extra features
and operational characteristics to be programmed into the radio. Your dealer can help define the
best operational settings for your system and program them into the radio.
3.13.1 SCAN DELAY
Scan delay lets the radio receive a response to a transmission before
scanning the other channels for activity. If you find that your scanner is
restarting before message replies are received, you can ask your dealer to
increase the scan delay time (0-7.5 seconds).
This timer is also used to allow for Talkback Scan.
