26 BK Radio
TONE CHANNEL GUARD VALUES
The Tone Channel Guard system may be set for any frequency in the
range of 67 to 255.9 Hz. However, since most systems adhere to the
Electronic Industry Association (EIA) standards, tones should be
selected from the following EIA list. In order to insure optimum
performance, tone selection for use on the same radio frequency (RF)
channel or adjacent channels in the same coverage area should be
made from one of the Groups A, B, or C to the maximum degree
possible. BK Radio guarantees optimum receiver performance only if
tone frequencies below 220 Hz are chosen.

Keypad Programming Manual 3
5. Release the [FCN] key and the master
switch. The radio is now in the Password
Entry Mode.
6. Enter the six-digit password code. Without
the correct password code, you cannot
proceed with programming.
NOTE: New radios shipped from the
factory are assigned the password code
000000.
If the password code is entered incorrectly,
the radio will reset to normal operation. Try
again, starting at step 2.
7. Press the [ENT] key to proceed to
Programming Mode. The display will change
to ‘PRG CH 00’.
NOTE: Keypad Programming Mode cannot
be entered when the radio is operating in
the Command Group. If the display flashes
“CMND GRP” when you try to enter
Programming Mode, release the master
switch and [FCN] key, and select a different
group.
A. NAVIGATION
When Programming Mode is entered,
programming starts (after password entry) with
the Group Parameters (CH 00) for the currently
selected group. To edit another Channel Group
(GRP 01 - 25), press and hold the [#] key at any
CH prompt to get the group selection prompt.
Enter the number of the group to be
programmed, or press the [PRI] key to
increment to the desired group. Once the
desired group is selected, press [FCN] to
access the data. Press the [FCN] key
repeatedly to cycle through the data fields, and
then loop back to the CH 00 entry point.
