INTRODUCTION AND GENERAL DESCRIPTION
Introduction:
Congratulations for your purchase of the MRC-11X bike-to-bike radio communicator
with driver/passenger intercom. Designed with special features for motorcycle,
snowmobile and other helmet/hard hat applications, the Nady MRC-11X offers the
most advanced portable communication technology available to allow you to stay
connected on the road. Offering several times the range of previous generation
motorcycle communicators, the MRC-11X provides maximum clarity and effortless
communication in the real world of motorcycle riding environments. Because the
MRC-11X operates with higher power on the special new uncluttered UHF FRS/
GMRS (U.S.) frequencies, you can now speak with another cyclist up to 7 miles away
(depending on the terrain) without interference.
Welcome to the next generation of personal communication: FRS & GMRS.
The FCC (Federal Communication Commission) has created 14 license free
frequency bands, or channels, called Family Radio Service (FRS) frequencies, and 15
licensed channels for General Mobile Radio Service (GMRS). These channels are in
the UHF (Ultra High Frequency) band, which virtually assures crystal clear reception
even in crowded noisy environments. This two-way, short-range voice radio service
lets families and groups keep in touch with each other on specific service channels.
The MRC-11X is compatible with other brands utilizing the same frequency band
(operating in the frequency range from 462.563MHz to 467.713MHz).
General Description:
Your MRC-11X includes a basic FRS and GMRS radio with 38 CTCSS tones and 22
channels (FRS & GMRS-7 channels FRS only, 8 channels GMRS only, & 7 channels
shared GMRS/FRS frequencies), and crystal clear communication range of up to 7
miles on the GMRS only channels. It provides excellent communication range and
voice quality, and user-friendly features. With special features for use with
motorcycles, the MRC-11X is designed to maximize your on-the-road
communications. The two-way radio can be voice-operated by either the driver or
passenger (VOX) or operated manually by either a remote PTT button mounted on
the handlebar or the large push-to-talk button (PTT) on the unit. The radio operates
simplex (one-way-at-a-time) mode for use by any number of riders on separate
motorcycles. The deriver/passenger intercom is full duplex (simultaneous two-way).
Auxiliary stereo input allows you and your passenger to listen to CD, tape players, or
other external music sources.
To assure the maximum performance of your unit, read these instructions
carefully and retain them for future reference.

WARNINGS
• While this unit has been designed for ruggedness, it is a precision piece of
electronic equipment that should not be exposed to water or handled carelessly.
Normal care should result in years of trouble-free operation.
• Do not leave batteries installed over a long period of time as leakage may occur,
which can destroy the unit. All batteries can cause property damage and/or bodily
injury, such as burns, if conductive material such as jewelry, keys or beaded chains
touch exposed terminals. The material may complete an electrical circuit (short
circuit) and become quite hot. Exercise care in handling any charged battery,
particularly when placing it inside a pocket, purse or other container with metal
objects.
• The antenna is permanently attached to the unit. Never attempt to remove it. Do
not use any unit that has a damaged antenna. If a damaged antenna comes in
contact with the skin, It may cause a minor burn.
• For vehicles with an air bag: Do not place your unit in the area over an air bag or in
the airbag deployment area. Air bags inflate with great force. If a unit is placed in
the air bag deployment area and the air bag inflates, the unit may be propelled with
great force and cause serious injury to the occupants of the vehicle.
WARNINGS
• Potentially Explosive Atmospheres: Turn your unit OFF when in any area with a
potentially explosive atmosphere, such as at a gasoline station filling area. Sparks
in such areas could cause an explosion or fire, resulting in bodily injury or even
death. Do not replace or charge batteries in a potentially explosive atmosphere.
Contact sparking may occur while installing or removing batteries and cause an
explosion. NOTE: Areas with potentially explosive atmospheres are often but not
always, clearly marked. They include fueling areas such as below deck on boats,
fuel or chemical transfer or storage facilities: areas where the air contains chemicals
or particles, such as grain, dust, or metal powders: and any other area where you
would normally be advised to turn off your vehicle engine.
• Blasting Areas: To avoid possible interference with blasting operations, turn your
unit OFF near electrical blasting caps or in a blasting area or in areas posted. Obey
all signs and instructions.
• Never connect this unit to more than 7.5 volts as will seriously damage the unit and
void the warranty. Never, for example, attempt to hook up external power to the
CHG (charger) power input from the motorcycle’s cigarette lighter or other source of
12V. You cannot operate the unit on external power.
• Do not open your radio to make any internal adjustments. Your radio is set up to
transmit a regulated signal on one of the 22 assigned frequencies (FRS/GMRS). It is
against the law to alter or adjust the setting inside the radio to exceed those
limitations. Any adjustment to your radio must be made by a qualified technician
using the proper test equipment. Note that such tampering will void the warranty.
• Always save your receipt as you will need it to establish proof-of-purchase date if
your unit ever needs service under the warranty.
TO BE SAFE
