6. Installation Instructions
1) Mount the JMCB-2003 to the left handlebar using the mounting bracket kit that is
applicable to your specific make and model of motorcycle. (Mounting Bracket Kits are
sold separately.)
2) Route the wires from the CB radio down the handlebar. Plug in the white 9-pin plug
from the supplied wiring harness. Connect the power wire (red) to a switchable power
source or accessor y terminal so that the unit is automatically turned off when the igni-
tion is turned off. Connect the black wire to a frame ground (not to the battery nega-
tive). If it becomes necessary to replace the fuse, use a 5 amp fuse for the red wire.
3) Connect the black 3-pin plug to the auxiliary audio cable and route the cable to the
auxiliary audio source.
4) Route all other cables where desired and hook them up according to the wiring dia-
gram.
5) Secure all wires and cables with the zip ties provided.
7. Operation of the JMCB-2003
1) With a helmet headset connected to the JMCB-2003 turn the ignition switch to the
ON position.
2) Rotate the SQUELCH knob on the JMCB-2003 fully clockwise.
3) Adjust the OFF/ON CB volume knob to a comfortable volume level and select the
desired CB channel.
4) Rotate the SQUELCH knob counterclockwise until the background noise is removed.
5) Plug in your auxiliary audio/music device and adjust the AUX VOL control on the
JMCB-2003 fully clockwise to maximum volume. Adjust the volume on the auxiliary
audio source to a maximum level just before distortion and then adjust the AUX VOL
control on the JMCB-2003 down to comfortable level. Further volume adjustments
while riding should be made with the CB mounted AUX VOL control only.
6) The intercom volume can be adjusted by pulling out the CB VOL OFF/ON knob.
Turning the knob clockwise will increase the intercom volume. When the intercom has
been adjusted to a comfortable level, push the VOL OFF/ON knob back to the inward
position.
7) Weather channels can be accessed by depressing the MODE button once then using
the CH UP and CH DN buttons to select one of the ten weather channels.
The National Weather Service uses several special radio frequencies to provide con-
tinuous reports of the local weather conditions and forecasts throughout the United
States. Taped weather messages are repeated every four to six minutes on a 24-hour
basis and are routinely revised every one to three hours, or more frequently if needed.
During severe weather, the routine weather broadcasts will be interrupted with spe-
cial weather warning messages.
The JMCB-2003 is designed to receive all these special weather frequencies plus
three international marine frequencies. An NOAA Weather Radio Network Frequency
pamphlet is enclosed to identify the frequencies specifically broadcast for your geo-
graphical area.
The JMCB-2003 receives CB, National Weather Service and international marine
weather broadcast frequencies as listed below:
CB Channels 1-40 26.965 to 27.405 MHz
Weather Channels 01WX 162.550 MHz
02WX 162.400 MHZ
03WX 162.475 MHz
04WX 162.425 MHz
05WX 162.450 MHz
06WX 162.500 MHz
07WX 162.525 MHz
Int’l Marine 08WX 161.650 MHz
09WX 161.775 MHz
00WX 163.275 MHz
8) Function indication “beep” can be turned on or off by depressing the MODE button
two (2) times. The LCD display will show the word ON or OFF. To turn the beep on or
off, switch between the CHL UP and CHL DN buttons.
8. Antenna Information
The maximum allowable CB transmitting power is limited by FCC regulations. The
antenna is a major component in the strength of the CB radio’s transmission signal
and its reception range.
A minimum distance of 18” between the CB antenna and the operator or passenger of
the motorcycle should be maintained.

Noise and Interference
Motorcycle audio systems are by their very nature noisy. While we do not guarantee this
system to be completely free from electrical noises and interference, we have taken
many steps to achieve that goal: the power supply system is well filtered and the cables
associated with the unit are shielded.
Most modern day motorcycles have resistor-type spark plugs installed by the factory. It may
be necessary to insure that resistor-type spark plugs are installed on your motorcycle.
Two Year Warranty
J&M Corporation warrants each new product it manufactures to be free

ered to us, intact, for our examination, with all transportation charges
prepaid to our factory, within two (2) years from the date of the sale to
the original purchaser. The provisions of the warranty shall not apply to
any unit which has been subject to misuse, neglect, incorrect mechani-
cal or electrical installation, unauthorized modifications, accident, nor to
