INSTALLATION AND PROGRAMMING
2.1
GENERAL INFORMATION
This section contains information concerning the installation and programming of BK Radio GMH
Series radios.
2.1.1 Unpacking and Inspecting Equipment
Exercise extreme care when unpacking the equipment. Make a visual inspection of the unit for
evidence of damage incurred during shipment. If a claim for damage is to be made, save the shipping
container to substantiate the claim. The claim should be promptly filed with the transportation
company. It would be advisable to retain the container and packaging material after all equipment has
been removed in the event that equipment storage or reshipment should become necessary.
2.1.2 Installation
Plan your installation carefully. Locate the radio and microphone within easy reach, giving the
operator a clear view of the display. Do not locate the radio or microphone in a position that interferes
with safe operation of the vehicle.
Once the equipment location is chosen, determine the best routing for cables and wires to connect
the system. Use a rubber grommet to protect the wires when passing through sheet metal. Avoid any
route that subjects the wire to pinching, cutting, or high heat from the engine or other vehicle
component.
The radio must be used with a 12 volt, NEGATIVE GROUND electrical system. Refer to Figure 2-1.
1. Crimp the fuse holder in line with the red power lead as close to the battery as possible.
2. Connect the red power lead to the vehicle battery POSITIVE terminal. Using other positive
voltage points in the vehicle is not recommended.
3. Connect the black lead to a good ground point on the vehicle chassis. Connection to the
negative battery terminal is not recommended.
4. Mount the antenna carefully. Follow the instructions supplied with the antenna kit. Route the
coax cable to the radio mounting location.
5. Fasten the mounting bracket securely to the desired location.
6. Mount the microphone clip securely to the desired location. The microphone hanger clip must
be grounded for proper radio operation. Use the supplied ground wire if needed.
7. Mount any approved accessory speakers and route the wires to the rear of the radio bracket.
8. Connect the power lead, antenna connector, and accessory wires to the rear of the radio.
9. Place the radio in the mounting bracket, adjust to the proper mounting angle, and thread in
the two side mounting knobs until the unit is secure.
NOTE: Option A and B connections are logic level outputs. Consult your BK Radio dealer before
connecting accessories to these pins.

A portable radio with a keyboard and display can transfer its programmed settings to an GMH radio
by using a cloning cable. A radio cannot transfer Alphanumeric display settings, including channel
labels and group labels.
Both units must be of the same frequency band. Settings for any group in a portable radio can be
downloaded to any group in the GMH radio. The GMH radio must be programmed with groups of 14
channels. Cloning can only be accomplished group by group. To perform group cloning:
1. With the portable radio in normal operation mode,
press the [#] key followed by number keys to select
the group to be downloaded.
2. Set the GMH radio to the group that is to receive the
download, using the same method as in step 1, or
by pressingthe GRP button and turning the Channel
Select knob.
3. Connect the Master end of the cloning cable into the
microphone connector of the portable radio. This is
the cable end with the pushbutton Master switch.
4 Put the portable radio into programming mode by
holding down the Master switch and pressing the
[FCN] key until the display shows ---ID.
5. Enter the correct Password Code.
6. Press the [FCN] key repeatedly to review the values
in Channel 0. Make any required changes at this
time.
7. Attach the other end of the cloning cable into the
microphone connector of the EM H radio to be
cloned.
8. Press the [*] key on the portable radio. The display
will flash PROG, signifying that the radio is ready to
download.
9. Press the [FCNJ key. The program in the portable
will download to the GMH. The GMH will send back
the program to the portable to verify successful
cloning.
10. If the download was successful, the portable radio
will resume flashing PROG. Turn off the GMH radio.
Disconnect the cable. Normal radio operation will
occur the next time the GMH radio is turned on.
11. If the download was not successful the portable
radio will flash FAIL, followed by continuous beeps.
Failure to download the portable program can be
due to:
A.
B.
C.
Incorrect radio types.
Improper connection.
Failure to power up radio.
NOTE: To stop FAIL mode, press the [CLR] key,
turn off the radios, and start again at Step 1.

2.3.1 Special Cloning Instructions
It is possible to change Channel 0 values on the portable radio, hold them in a temporary memory,
and download them to the GMH without actually entering them into the permanent memory of the
portable radio. This is convenient for sequential identification numbers used to identify a series of
portables in a radio system. Assuming that the frequencies, Code Guard values, and other Ch 0
values are common for all radios in the system, but that the radio identification number should be
unique to each radio, the following method would be used to clone additional radios for the system.
1. Program the portable radio with all frequencies,
Code Guard values, and Channel 0 values that will
be common to all GMH radios to be cloned.
2. Advance the display to show the portable radio's ID
number-for example, 100.
3. Press the [CLR] key; press 125. Do not press the
[ENT] key. Now 125 is in temporary memory.
4. Press the [*] key, connect the cable to the radios
and download to the GMH by pressing the [FCN]
key. ID number 125 is now stored in permanent
memory of the GMH.
5. After download, press the [CLR] key on the portable
radio. Disconnect the GMH. The portable radio
display will show that 125 is still being held in the
temporary memory of the portable radio.
6. Press the [PRI] key. This will increment the ID
number one digit to 126. (Note: any new number can
be entered at this point by pressing the [CLR] key
and using the digit keys to enter the new number.)
7. Press the [*] key. Connect the cable to the second
GMH and download by pressing [FCN].
8. Any number of radios can be coded with different or
sequential ID numbers using this technique. The ID
number in the permanent memory of the portable
radio will remain unchanged as 100.
2.3.2
Scan List and Priority Channel Cloning
When a portable radio downloads to an GMH, the
Scan List and Priority Channel designations are also
transferred to the GMH. This includes Priority Mode
and any lockout functions.
To program an GMH with a specific Priority Mode,
Priority Channel, and Scan List along with the
respective lockout functions (if desired), the portable
radio must first be programmed with these
parameters. The lockout functions cannot be held in
temporary memory. See the appropriate operating
procedures in Section 3 for selecting the Scan List,
Priority Channel, and Lockout functions.
See
"Priority Scan" on page 2-6 for Priority Mode
selection procedures.

Programming a radio from a computer is not covered in this manual. Contact BK Radio for the
programming cable, software, and manual required.
2.3.3
Tone Code Guard Values
The tone Code 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.
BENDIX/KING
guarantees optimum receiver performance only if tone frequencies below 220 Hz are chosen.

Digital Code Guard Values
Codes for the Digital Code Guard system may be chosen from the following list. This can be done
during the code programming of the system. Usually systems using direct unit to unit transmission
(systems without mobile relays, repeaters, remote control, etc) may use codes from the table.
Systems with relays etc. may use code variations for system control and operational efficiency. The
system operator or engineer should be consulted regarding the operational requirement on such
systems.
