Installation and Operation Manual

WARNING AND COMPLIANCE

Important Safety Instructions

• To ensure full satisfaction with the product, please read the entire instruction manual.
• Keep instructions for future reference.
• Follow all operation guidelines and adhere to all safety warnings and cautions to ensure safe use.
• Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
• Only use attachments/accessories specified by the manufacturer.
• Never use harsh cleaning agents. Clean only with a dry cloth.

When Operating Vessel

• Keep the volume level low enough to be aware of your surroundings. Protect from Submersion
• Do not submerge, as this can cause electrical shorts, fire, or other damage.

Protect from High Temperatures

• The space behind the chosen mounting location should allow room for the radio heatsink to dissipate heat generated under normal use. Do not mount the radio within close proximity of the engine compartment.

Use the Proper Power Supply

• This product is designed to operate with a 12 volt DC negative ground battery system.

WARNING:

• DO NOT OPEN, DISASSEMBLE OR ALTER THE UNIT IN ANY WAY.
  Doing so may result in fire, electric shock, or product damage.

• USE THE CORRECT AMPERE RATING WHEN REPLACING THE FUSE.
  Failure to do so may result in fire, electric shock, or product damage.

• DO NOT INSTALL IN LOCATIONS THAT MIGHT HINDER VEHICLE
  OPERATION. Doing so may obstruct vision or hamper movement which can result in a serious accident.

• INSTALL THE WIRING SO THAT IT IS NOT CRIMPED OR PINCHED BY SCREWS ORSHARP METAL EDGES. Route the cables away from moving parts or sharp pointed edges. This will prevent crimping and damage to the wiring. If the wiring must pass through a metal hole, be sure to use a rubber grommet to prevent the wire’s insulation from being cut by the metal edge of the hole. It is also recommended to apply sealing caulk to any opening that may potentially allow water to enter.

• Be sure to choose a location that is flat and has clearance above the unit to prevent any damage, as well as allow for ventilation.

• Before drilling any holes, carefully inspect the area underneath and behind the mounting surface where the device will be mounted to make sure it will
  not interfere with existing wires, fuel lines, the fuel tank, or any other objects that could be damaged.

• Always disconnect the vehicle negative battery terminal during installation to prevent accidental shorting.

INSTALLATION

Important Notes

• Before you begin, always turn off the batteries at the battery switch. If no battery switch is installed on the vessel, you can disconnect the negative terminal from your battery.
• Before final installation, test the wiring connections to make sure the unit is connected properly and the system works.
• Consult with your nearest dealer if installation requires the drilling of holes or other modifications to your vessel.
• Install the unit where it does not interfere with the driving and cannot injure passengers if there is a sudden or emergency stop.

Mounting the Radio

1. Choose a mounting location on the helm, in the glove box, or desired area of the vessel that will allow room behind to run radio cables to the power source. Consider how you will use the AUX IN, LINE OUT, and USB connectors and route the appropriate extension cables to an accessible area.

2. Refer to the dimensioned diagram on the right to cut the installation opening.
   IMPORTANT! Do not mount this unit where it can be submerged in water.

3. Cut a hole in the chosen mounting location using the template provided in the back of this manual. At least 4.5” depth is needed to mount the radio.

4. Slide the included spring washers (B) over the screw posts (A) and attach the screw posts to the back of the radio

5. Place the radio in front of the mounting opening so the wiring can be brought through the opening.
   NOTE: Before final installation, test the wiring connections to make sure the unit is connected properly and the system works

6. After completing all wire connections, turn the radio on to confirm operation (battery switch will need turned back on or negative cable will need to be attached for this test). If the radio does not operate, recheck all wiring until the problem is corrected. Once the proper operation is achieved, turn the battery switch off or disconnect the negative cable from the battery.

7. Insert the radio into the mounting hole and make sure it is right-side-up.

8. Place the “U” bracket (C) over the screw posts and secure the radio to the chosen mounting position using the included hex nuts (D). If necessary, cut the score marks (E) on either side of the mounting bracket to custom fit the bracket length for your application. See Figure A.

Auxiliary Input
Connect a portable audio device to the Audio Input (AUX-IN RIGHT/LEFT) on the back of the unit using RCA cables.
Line Output
The Line Out connectors (LINE OUTRIGHT/LEFT) on the back of the unit output a line-level analog signal. Use this output to connect to an external amplifier.

APP OPERATION

MARINE Audio app (no longer supported beginning in 2021)

ASA Audio app (available Fall 2020)

MARINE Audio Specialty Controller is the ultimate wireless remote control for your stereo system. Store away your old remotes and enjoy the convenience of all the primary functions of your stereo right from your phone or tablet by transforming your mobile device into a functional stereo remote control!
Features
This app controls all of the primary functions of your stereo features including:

• Power on/off
• Mode Selection
• Volume control
• Play/Pause or Mute
• AM/FM radio tuner: seek.
• Bluetooth streaming audio
• Audio menu control: Bass, Treble, Balance, Fader, and Loudness on/off.

Connecting and using App from App Store
After downloading and installing the app on your device, pair your device to the MA112 as stated above for Bluetooth pairing. Once your device is paired you can open the app and use it with your MA112 radio.
When the app is installed on the Android operating system, you may need to close the app before Bluetooth pairing, otherwise, there may be errors in the Bluetooth connection.

CARE AND MAINTENANCE

• Keep the product away from dust and dirt, which can cause premature wear of parts.

• Handle the product gently and carefully. Dropping it can damage circuit boards and cases, and can cause the product to work improperly.

• Wipe the product with a dampened cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents
  to clean the product.

• Use and store the product only in normal temperature environments. High temperatures can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.

Ignition
The most common source of noise in reception is the ignition system. This is a result of the radio being placed close to the ignition system (engine). This type of noise can be easily detected because it will vary in intensity of pitch with the speed of the engine.
Usually, the ignition noise can be suppressed considerably by using a radio suppression type high voltage ignition wire and suppressor resistor in the ignition system. (Most vessels employ this wire and resistor but it may be necessary to check them for correct operation). Another method of suppression is the use of additional noise suppressors. These can be obtained from most CB/A radio or electronic supply shops.

Interference
Radio reception in a moving environment is very different from reception in a stationary environment (home). It is very important to understand the difference.
AM reception will deteriorate when passing under a bridge or when passing under high voltage lines. Although AM is subject to environmental noise, it has
the ability to be received at a great distance. This is because broadcasting signals follow the curvature of the earth and are reflected back by the upper atmosphere.

Select a station manually, if signals are too weak.
Check the condition of the antenna coax. Ensure it is not being pinched or shorted. Note: antenna mounting location, type of antenna, environmental conditions, and physical proximity of the tuner with relationship to the transmitting tower all play a role in the ability to tune in a specific radio station.
Cannot connect or pair a Bluetooth Device| Check the radio to ensure not connect to any Bluetooth devices. Refer to page 8 for disconnecting the Bluetooth device.
