This device complies with Part 15 of the FCC rules. Operation is subjected to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

NOTICE
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.

FCC WARNING

● Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
● Proper connections must be used for connection to a host computer and/or peripherals in order to meet FCC emission limits.

Safety Information

• 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 Driving
Keep the volume level low enough to be aware of the road and traffic conditions.
Protect from Water
Do not submerge, as this can cause electrical shorts, fire, or other damage.
Protect from High Temperatures
Exposure to direct sunlight for an extended period of time can produce very high temperatures inside your vehicle. Give the interior a chance to cool down before starting playback. 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 OR SHARP 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’s negative battery terminal during installation to prevent accidental shorting.

INSTALLATION

Mounting the Radio

1. Choose a mounting location on the dashboard or instrument panel that will allow room behind to run radio cables to the power source. Consider how you will use the AUX IN, LINEOUT, and USB connectors and route the appropriate extension cables to an accessible area.

2. Cut a hole in the dashboard using the template provided in the back of this manual. At least 3 ¾” depth is needed to mount the radio.
   IMPORTANT! Do not mount this unit where it can be submerged in water.

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

4. Place the radio in front of the dashboard opening so the wiring can be brought through the opening.

5. After completing the wiring connections, turn the radio on to confirm operation (vehicle accessory switch must be on). If the radio does not operate, recheck all wiring until the problem is corrected. Once the proper operation is achieved, turn the accessory switch off and proceed with final mounting of the radio. Refer to the “Wiring Diagram” on page 4.
   NOTE: Before final installation, test the wiring connections to make sure the unit is connected properly and the system works.

6. Insert the radio into the mounting hole.

7. Place the “U” bracket (C) over the screw posts and secure the radio to the dash 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 OUT RIGHT/LEFT) on the back of the unit output a line-level analog signal. Use this output to connect to an external amplifier.
