WELCOME TO THE WORLD OF MIDLAND RADIO
Congratulations on your purchase of a high quality MIDLAND product.Your
MXT400 2-way radio represents state-of-the-art high tech engineering.
Designed for General Mobile radio Service (GMRS) operation, this
compact package is big on performance. It is a quality piece of electronic
equipment, skillfully constructed with the finest components. The circuitry
is all solid-state and mounted on a rugged printed circuit board. Your
MXT400 radio is designed for reliable and trouble-free performance for
years to come.
FEATURES
––15 GMRS Channels
Model MXT400
FCC NOTICE
The MXT400 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,
15-22 or RP15-22, which comprise the GMRS channels of the MXT400.
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.
––8 Repeater Channels
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:

▪▪ To control your exposure 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.

INSTALLING YOUR RADIO
Preparation for Installation
Model MXT400
Installing the Mounting Bracket
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. Using the mounting bracket as a
template, mark the location of each
screw hole. Use a nail or other sharp
pointed object to mark the hole
locations.
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.
2. Attach the bracket with the supplied
self-tapping screws. Tighten
the screws securely. DO NOT
OVER-TIGHTEN.
5. Determine a mounting location for your radio. 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.
CAUTION: Extreme care should be exercised when drilling into
the dash to avoid damage to under dash electronic ignition,
cruise control, instrument and/or accessory wiring.

3. Determine the best suited position
for using the radio, then insert and
tighten the supplied SEMS screws.

Electrical and Rear Panel Connections
Installing the Antenna
To get the best range from the MXT400 an external antenna (50Ω) should
be used. The antenna is 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. Metal surfaces covered by fiberglass or vinyl may affect radio range.
Avoid these locations.
2. Mount the antenna as high on the vehicle as possible. The higher the
better.
3. If possible, mount the antenna in the center of whatever surface you
choose.
4. 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.
5. Be sure the mounting location is clean and dry before installing the
antenna.
6. Route the antenna cable through an accessible entry point, such as a
rear door or trunk opening.
7. When routing the antenna cable inside the vehicle, keep the cable
away from noise sources, such as the ignition system, gauges, etc.
8. Exercise care to prevent cable damage. Make use of existing gaskets,
grommets and weather stripping to protect the cable along its route.
Page 8
Model MXT400
midlandusa.com
Refer to Rear Panel Connections for rear panel connector locations.
NOTE: Radio antenna is installed separately.
Connecting the Radio to a Power Source
1. 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 power cord positive lead can also be connected to the Accessory
terminal on the fuse block or ignition switch, so the radio automatically
turns off when the ignition is turned off.
2. Tightly 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.
Connecting the Microphone
Insert the RJ45 connector into the front of the MXT400. To remove, lightly
pinch the bottom region of the boot assembly of the Microphone and gently
pull towards you.
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 MXT400 provides a rear-panel jack for connection of an optional
external speaker (sold 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
speaker is automatically disabled.

Selecting a Privacy Code
Continuous Tone Coded Squelch System (CTCSS) and Digitally Coded
Squelch (DCS) are systems that allow several users to share the same
channel without disturbing each other. When CTCSS or DCS are enabled
for a selected channel, the channel is muted to all incoming signals unless
they carry the correct CTCSS or DCS tone.
When a transmission with the correct tone is received, the mute is
removed and the voice audio can be heard. When the transmission ends
the channel is muted again. Transmissions that do not have the correct
tone are not heard.
The MXT400 has 142 Privacy Codes (38 CTCSS codes and 104 DCS
codes), which can be applied to any channel. If desired, you can select
a different Privacy Code for each channel. See CTCSS Privacy Codes
Frequency Chart and DCS Privacy Codes Chart for lists of available
Privacy Codes.
IMPORTANT! To communicate between two MXT400 radios or any GMRS
radio, both radios must be set to the same channel (see Selecting the
Active Channel) and Privacy Code selections.
To select a CTCSS Privacy Tone:
1. Press the TS/DCS button once to enter the CTCSS Privacy Code
settings.
Call Alert
Your radio can transmit a call alert for a fixed length of time.
To send a call alert
