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 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 negative battery terminal during installation to prevent accidental shorting.

INSTALLATION
Mounting the Radio
1. Choose a mounting location on the dash board or instrument panel 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. Cut a hole in the dash board 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 proper operation is achieved, turn the
accessory switch off and proceed with final mounting of the radio. Refer to the “Wiring Diagram” on page 5.
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.
