IMPORTANT! Changes or modifications to this unit not expressly approved by
MIDLAND RADIO CORPORATION could void your right to operate this
unit. Your radio is setup to transmit a regulated signal on an assigned
frequency. It is against the law to alter or adjust the settings inside the
COMMUNICATOR to exceed those limitations. Any adjustment to your radio must be made by qualified technicians.

FCC NOTICE

The MXT105B 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 MXT105B. Serious penalties may result from unlicensed use of GMRS channels, in violation of FCC rules, as stipulated in the Communication Act’s Section 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 license application, contact the FCC at 1-888-CALL FCC or go to the FCC’s website: https://www.fcc.gov/wireless/universal-licensing-system#filing click on the link “File OnLine” and follow the instructions to obtain a FRN and log in to complete form 605.

Exposure 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-lonizing Radiation Protection (ICNIRP) 1998
• To control your exposure and ensure compliance with general population 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 cm) 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 MXT105B is designed to be installed under the dash or vertically on the center console. 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 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.

Installing the Mounting Bracket

Power and Antenna Connections

Rear Panel Connections

• A. ANT Jack – SO-239 UHF connector for external antenna (included)
• B. EXT SPKR Jack – 3.5mm audio connector for optional speaker (purchased separately) (see Using an External Speaker for specifications)
• C. DC POWER Jack – 2-pin DC connector for 12V DC nominal input power connection

Installing the Antenna

The MXT105B comes with a magnetic mount antenna that can be easily placed on a vehicle’s roof, trunk or other location that can provide a metal ground plane. Proper placement is important to the overall performance of the radio. Follow these guidelines to help you decide where to place it.

• Mount the antenna as high on the vehicle as possible. (The higher the better).
• The antenna must be on a flat, clean, metal service to create a ground plane. Surfaces covered with vinyl or fiberglass will negatively affect the performance.
• Make sure the cable (6 meters, about 20 feet) can easily be routed to the radio and does not cause interference with the vehicle operation.
• Keep the antenna and cable away from noise sources such as the ignition and electrical systems or gauges.
• Be sure not to crimp or damage the antenna or cable during installation.
• Look for existing entry points when routing the cable such as a rear window, trunk or hood opening, firewall grommets or other areas where weather protection is provided.
• Do not alter the antenna or cable as it is pre-matched to your radio for peak performance.

1.Power Connection

The power cord supplied with the MXT105B is equipped with a DC vehicle power port for easy installation. Simply plug the power cord into the connector C on the back of the radio and plug the DC adapter into the vehicle’s DC power port.

Follow these steps if you prefer to direct “hard wired” connection. Make sure the vehicle power is off while making all connections.

• a. Plug the power cable into the connector C on back of the radio.

• b. Cut the DC Power vehicle adapter off the other end of the cord.

• c. Carefully route the power cord to a 12-volt DC power source, such as the fuse block or battery terminal, making sure not to cause interference with the vehicle operation, and avoid noise sources as describe above.
  NOTE: The fuse block is the recommended connection point as it is usually the most convenient and the radio will turn on/off with the vehicle when using an accessory terminal. Check your vehicle owners guide for location and proper connection.

• d. Connect the red wire (with in-line fuse) to the positive (+) accessory connector in the fuse block (recommended) or positive (+) battery terminal.

• e. Connect the black wire (ground) directly to a metal service on the vehicle or the negative (-) battery terminal.

2. Antenna Connection

Simply screw the antenna connector on the antenna cable onto the connector A (SO-239) on the back of the radio.

• a. Carefully coil any excess cable and use a tie strap to secure it out of the way of vehicle operation.

• b. Do not cut, crimp, or alter the cable or the connector is any way as it is pre-matched to your radio.
  NOTE: The fuse block is the recommended connection point as it is usually the most convenient and the radio will turn on/off with the vehicle when using an accessory terminal. Check your vehicle owners guide for location and proper connection.

• d. Connect the red wire (with in-line fuse) to the positive (+) accessory connector in the fuse block (recommended) or positive (+) battery terminal.

• e. Connect the black wire (ground) to directly to a metal service on the vehicle or the negative (-) battery terminal.

3. Optional External Speaker Connection (Not included)

The MB105B provides a 3.5mm mono jack B connection for an external speaker.

• a. Use only approved Midland accessories.
• b. Speaker must be 8-ohm, minimum rating of 4 watts. Center pin (tip) positive.

NOTE: The MB105B’s internal speaker is disabled when an external speaker is connected.
