BK RADIO 

GBH Owner's Manual 

USER SELECTED CODE GUARD 

User Selected Code Guard is only available on radios equipped with a 
keypad microphone. Not all microphones support this function.  Contact 
your dealer to determine which features are available with your 
microphone and have been enabled in the radio. 

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.  If 
User Code Guard selection is enabled, the Code Guard values for any 
channel can be temporarily assigned to the knob-selected channel.  

For example, to use the Code Guard values of Channel 9 with the 
frequencies of Channel 5: 

1.  Turn Scan and Priority Scan OFF. 

2.  Turn the Channel Selector knob to Channel 5. 

3. Press 

the [9] key on the microphone keypad. The display shows 

CG

The radio will now operate on the frequencies of Channel 5 with Channel 
9 Code Guard values. The display shows the Code Guard channel (9), 
and then the selected channel (5). 

Press the microphone’s [#] key to display the Code Guard channel 
briefly. The display shows the group number, followed by the Code 
Guard channel, and then the selected channel.  

Press the [0] key to reset all values to the original programming, or press 
different number keys (1-16) to select a different set of Code Guard 
Values. 

NOTE:  During Scan or Priority Scan, the display does not show user-
selected Code Guard values, nor does it qualify incoming signals with 
the user-selected Code Guard values in Scan mode. 

GROUP SCAN 

Channels on each "channel scan list" and groups on the "group scan list" 
are scanned sequentially. The knob-selected group is always scanned 
when Group Scan is enabled, even if that group is not on the group scan 
list. 

When Group Scan is enabled, the following features are disabled: 

• 

Dual Priority Scan 

• 

User-Selected Code Guard 

• 

Nuisance Channel Delete 

Selector knob to select a group. Return to Channel Select mode by 
waiting 5 seconds, or by pressing the GRP button one time (numeric 
mode) or two times (alphanumeric mode). After selecting a group in 
alphanumeric mode, press the GRP button one time to display the group 
label, and a second time to return to Channel Select mode. 

SQL Squelch 

Adjust 

Press the SQL button to toggle between Squelch Adjust and Channel 
Select modes.  

Press the SQL button for Squelch Adjust mode. Turn the Channel 
Selector knob to adjust the squelch setting. Turning the knob counter-
clockwise tightens the squelch setting, allowing only stronger signals to 
open the squelch and be heard. In the absence of a held channel, the 
receiver will be tuned to the main channel. Guard qualification will be 
disabled during squelch adjustment.  

Return to Channel Select mode by pressing the SQL button again. 

 

Pressing the SQL button and holding for more than 1 second (until beep 
is heard) sets the squelch to its factory preset value. 

TA 

Repeater Talk Around 

Press the TA button to turn Repeater Talk Around on or off. When TA is 
on, the radio transmits on the receive frequency of the selected channel, 
bypassing or “talking around” the repeater. This function may be used on 
any channel that is programmed to a frequency pair (repeater channel). 

CG 

Code Guard Disable 

Press the CG button to disable or enable Code Guard operation. An 
arrow on the display points to the CG button when Code Guard is 
disabled. When Code Guard is enabled, a message is heard only when 
the proper Code Guard is received. Transmit Code Guard generation is 
unaffected. The CG button may also be used to override Busy Channel 
Lockout, if that is installed. 

HOM Home 

Channel 

Press the HOM button to go to the pre-programmed Home Channel. 

To set a different Home Channel, select the desired channel using the 
Channel Selector knob, press the HOM button, and hold it for more than 
1 second until the arrow above the HOM button appears on the display. 
The new channel then becomes the Home Channel.
