INSTALLING YOUR RADIO
Preparation for Installation
The MXT115 is designed to be installed in a 12-volt negative ground 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 engine block or vehicle chassis. Contact your dealer if you are unable to determine your vehicle’s polarity system.
•    Read these instructions completely before beginning installation.
•    Read and follow all safety precautions in your vehicle’s Service Manual.
•    Make sure all necessary tools, materials, and parts are on hand.
•    Disconnect the negative (-) battery cable before installing your radio. Be sure to reconnect the cable when installation is complete.
•    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.

Installing the Antenna
An external 50 Ω antenna is required for the MXT115. The standard 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 fibreglass 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.

Electrical and Rear Panel Connections

Refer to Rear Panel Connections for rear panel connector locations. NOTE: Radio antenna installation is covered separately.

Connecting the Radio to a Power Source

1.    The MXT115 can be powered by connecting the supplied power cable to a 12 V DC port in the vehicle.
OR
2.    Remove the 12 V power plug from the power cable and connect the RED positive lead to either (a) the fuse block or (b) directly to the positive post of the vehicle’s battery. NOTE: The in-cabin 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.
3.    Tightly connect the BLACK ground lead directly to the vehicle’s metal frame. A good direct metal-to-metal ground is essential for optimum performance.

Fuse

The power cord and 12V vehicle adapter both contain a 5A fuse, type F5AL, 0.25 x 1.25 in. (6 x 30 mm) and should be replaced with the same type when necessary.

Connecting the Microphone

Insert the microphone connector into the front of the MXT115 by lining up the key with the mating slot and gently twisting the locking collar clockwise to secure the connection. To remove, twist the locking collar counterclockwise and gently pull the connection free. The microphone bracket can then be attached to the vehicle dash or other convenient location.

Using an External Speaker

The MXT115 provides a jack for connection of an optional external speaker (sold separately). The external speaker jack is compatible with a 3.5 mm mono audio plug. When selecting an external speaker, ensure the speaker has 8-ohm impedance and is rated for 4 Watts or more.
NOTE: When an external speaker is connected, the radio’s internal speaker is automatically disabled.

Using a Public Address Speaker

The MXT115 provides a jack for connection of an optional public address speaker (sold separately) normally mounted on the vehicle exterior.
The PA speaker jack is compatible with a 3.5 mm mono audio plug. When selecting a passive PA speaker, ensure the speaker is weatherproof, has
8-ohm impedance and is rated for 4 Watts or more. Weatherproof amplified PA speakers may also be used.

Using an Intercom

The MXT115 provides a rear-panel jack for connection to a wired intercom or headsets (sold separately) with a TA5 mini XLR connector.

Operation

Many of the operational buttons have a short and long press function based on a two second timer. If the button is pressed then released in less than two seconds, the short press function is performed after the button

CTCSS/DCS (Privacy Tone)

Continuous Tone Controlled Squelch System (CTCSS) and Continuous Digital Controlled Squelch System (CDCSS, short version DCS) are systems that allow groups of users to share the same channel without disturbing each other. When CTCSS or DCS is enabled for a selected channel, the radio speaker is muted to all incoming signals unless they carry the correct CTCSS tone or DCS code.
When a transmission with the correct tone/code 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/code are not heard. Please note that users with different CTCSS/ DCS selections transmitting on the same frequency at the same time create interference.
The direct channels (without repeater transmit frequency offset) have a single CTCSS/DCS selection per channel, the PT menu selection, which is applied to both transmit and receive. The repeater channels (with repeater transmit frequency offset) have separate selections for transmit and receive CTCSS/DCS, the TXC and RXC menu selections.
