CMR270 

PREPARATION

Please read all instructions carefully before attempting to install or operate.

Due to its technical nature, it is highly recommended that your JENSEN CMR270 is installed by a professional 

installer or an authorized dealer. This product is only for use in vehicles with 12VDC negative ground only. 

To prevent damage or injury:

• Make sure to ground the unit securely to the vehicle chassis ground.

• Do not remove the top or bottom covers of the unit.

• Do not install the unit in a spot exposed to direct sunlight or excessive heat or the possibility of water splashing.

• Do not subject the unit to excessive shock.

• When replacing a fuse, only use a new one with the correct rating. Using a fuse with the wrong rating may cause 

the unit to malfunction.

• To prevent short circuits when replacing a fuse, disconnect the wiring harness first.

• Use only the provided hardware and wire harness.

• If you experience problems during installation, consult your nearest JENSEN dealer.

• If the unit malfunctions, reset the unit as described. If the problem still persists, consult your nearest JENSEN 

dealer or call tech assistance @ 1-888-921-4088.

• To clean the monitor, wipe only with a dry silicone cloth or soft cloth. Do not use a stiff cloth, or solvents such as 

paint thinner and alcohol. They can scratch the surface of the panel and/or remove the printing.

• When the temperature of the unit falls (as in winter), the liquid crystal inside the screen will become darker than 

usual. Normal brightness will return after the unit is in use for a while.

• When extending the ignition, battery or ground wiring, make sure to use automotive-grade wiring with an a 

minimum AWG 16 or more to prevent voltage drops.

• Do not touch the liquid crystal fluid if the LCD is damaged or broken. The liquid crystal fluid may be hazardous 

to your health or fatal. If the liquid crystal fluid from the LCD contacts your body or clothing, wash it off with soap 

immediately.
