FCC NOTICE
The MXT105 operates on GMRS (General Mobile Radio Service)
frequencies, which require a Federal Communications Commission (FCC)
license.
You must be licensed prior to operating on channels 1-7 or 15-22,
which comprise the GMRS channels
of the MXT105. Serious penalties
may result from unlicensed use
of GMRS channels, in violation of FCC
rules, as stipulated in the Communications Act's Sections
501 and 502
(amended).
You will be issued a call sign by the FCC that should be used
for station identification when operating your radio on GMRS channels.
You should also cooperate by engaging in permissible transmissions only,
avoiding channel interference with other GMRS users, and being prudent
with the length
of your transmission time.
To obtain a license or ask questions about the license application, contact
the FCC at 1-888-CALL FCC or
go to the FCC's website:
http:// www.fcc.gov and request form 605.
Expo~ure To Radio Frequency Energy
Your Midland radio is designed to comply with the following national and
international standards and guidelines regarding exposure
of human
beings to radio frequency electromagnetic energy.
• United States Federal Communications Commission, Code of Federal
Regulations: 47 CFR part 2 sub-part J
• American National Standards Institute (ANSI)/Institute of Electrical &
Electronics Engineers (IEEE) C95. 1-1992
• Institute of Electrical and Electronics Engineers (IEEE) C95. 1-1999 Edition
• National Council on Radiation Protection and Measurements (NCRP)
of
the United States, Report 86, 1986
• International Commission on Non-Ionizing Radiation Protection (ICNIRP)
1998
•
To control yourexposure and ensure compliance with the general popu-
lation
or uncontrolled environment exposure limits, transmit no more than
50%
of the time. The radio generates measurable RF energy exposure
only when transmitting.
• The consumer must maintain a minimum safe separation distance
of 15.5
inches (40 em) from the antenna

INSTALLING
YOUR
RADIO
Preparation for Installation
This radio may be installed in any 12-volt negative ground system vehicle
Most current U.S. and Foreign vehicles use a negative ground system,
but some older models and some newer large trucks may have a positive
ground. Check the specifications for your vehicle before beginning
installation. Generally, you have a negative-ground system
if
the negative
(-) battery terminal is connected to the motor block. Contact your dealer if
you are unable to determine your vehicle's polarity system.
1.
Read these instructions completely before beginning installation
2.
Read and follow all safety precautions in your vehicle's Service Manual.
3.
Make sure all necessary tools, materials, and parts are on hand.
4.
Disconnect the negative(-) battery cable before installing your radio.
Be
sure to reconnect the cable when installation is complete.
5.
Determine a mounting location for your radio. The MXT105 is designed
to be installed underthe dash
or
vertically on the centerconsole. Choose
a location that does not impair visibility
or
interfere with driving. Also take
into consideration the routing and length
of
the lead wires and cables to
the power source, antenna, and/or optional external speaker.
UNDER
DASH
MOUNT
CAUTION: Extreme care should be exercised when drilling into
the dash to avoiddamage to underdash electronic ignition,
cruise control, instrument and/oraccessory wiring.

Installing the Mounting Bracket
1.Using the mounting bracket as a
template, mark the location
of
each
screw hole under the dash. Use a
nail or other sharp pointed object to
mark the hole locations.
2. Attach the bracket to the dash with
the Phillips head sheet metal screws
provided. Tighten the screws
securely. DO NOT OVER-TIGHTEN.
3.
Slide the radio into the mounting
bracket. BE SURE the mounting
bracket retainers engage the slots
in
the sides
of
the radio to prevent
movement while driving.

Installing the Antenna
The MXT1
05
includes a "magnetic mount" antenna, intended to be
attached to the vehicle's roof, trunk
or
similar location. Specific installation
requirements vary between vehicles. Use the following guidelines to install
the antenna.
*Where you locate your antenna does make a difference.*
1.
Some general rules for antenna location that can aid radio
performance.
2. Metal surfaces covered by fiberglass
or
vinyl may affect radio range.
Avoid these locations.
3.
Mount the antenna as high on the vehicle as possible. The higherthe
better.
4.1f possible, mount the antenna in the center
of
whatever surface you
choose.
5. The antenna cable is 19.7 feet (6 meters) long. Be sure the mounting
location will allow for connection
of
the cable to the radio.
6. Be sure the mounting location is clean and dry before installing the
antenna.
7. Route the antenna cable through an accessible entry point, such as a
rear
door
or
trunk opening.
8.
When routing the antenna cable inside the vehicle, keep the cable
away from noise sources, such as the ignition system, gauges, etc.
9.Exercise care to prevent cable damage. Make use
of
existing gaskets,
grommets and weather stripping to protect the cable along its route.

Electrical and Rear Panel Connections
Refer to Rear Panel Connections for rear panel connector locations.
NOTE: Radio antenna is installed separately.
1. The power cord supplied with the MXT105 is equipped with a cigarette
lighter adapter for easy installation. Simply plug the connector into the
vehicle's cigarette lighter.
If a "hard-wired" installation is desired, connect
the power cord to the vehicle's electrical system as follows:
• Cut the power cord just after the cigarette lighter adapter.
• Connect the positive lead (RED wire with in-line fuse holder) to
either (a) the fuse block or (b) directly to the positive post
of the
vehicle's battery.
NOTE: The fuse block is usually the most convenient connection
point. The powercordpositive lead can also
be connected to the
Accessoryterminal on the fuse block
or ignition switch1 so the radio
automatically turns
off when the ignition is turned off.
• Securely connect the ground lead (BLACK wire) directly to the
vehicle's metal frame. A good direct metal-to-metal ground is
essential for optimum performance.
2. Connect the 2-pin plug-in connector
of the power cable to the 13.8V DC
jack on the rear panel.
3. Attach the antenna cable to the ANT jack on the rear panel.
4.1f desired, an optional external speaker (purchased separately) can be
connected to the EXT SPKR jack (see Using
an External Speaker).
Connecting the Microphone
Insert the RJ11 connector into the front of the MXT105. Once the
microphone is connected, use a small tool to insert the strain relief.
The microphone bracket can then be attached to the vehicle dash or other
convenient location in a manner similar to the mounting bracket.

Using
an External
Speaker
The MXT105 provides a rear-panel jack for connection
of
an optional
external speaker (purchased separately}.
When selecting an external speaker, ensure the speaker has 8-ohm
impedance and is rated for 4.0 watts.
NOTE: When an external speaker
is
connected, the radio's internal
speakeris automaticallydisabled.

Adjusting Squelch Sensitivity
The MXT105 has adjustable squelch sensitivity. The minimum squelch
level
of
00 is the most sensitive, which allows the squelch to open on very
weak signals. Setting the squelch to the maximum setting
of
