3 Before You Begin

1. Carefully read the Installation Guide before installing this product. If anything is unclear, please contact your

Customer Care representative for support.

2. Ensure that the NEGATIVE battery connection is disconnected before beginning work.

3. Ranger should only be serviced by qualified, trained personnel. Attempting to remove the cover or

disassemble the device could expose you to dangerous high voltage points.

4. Do not attempt to install or operate a damaged device. If the unit has been exposed to excessive amounts of

water; shows evidence of physical damage; or is not operating properly; unplug it from the power source and

contact qualified service personnel.

5. Use of thread-locking compounds such as Loctite may cause serious damage to plastic enclosures. Many

thread-locking compounds are not compatible with thermoplastics and can lead to stress cracking. This will

require the unit to be returned to replace the ABS enclosures.

3.1 Care and Cleaning of the Touch Panel

• Do not use high-pressure air, water or steam to clean the surface of the touch panel. The action may cause

the touch panel to malfunction.

• Clean the touch panel surface with a dry soft cloth; only alcohol or ammonia-based cleaners can be used with

caution when necessary.

• Always dampen the cloth and clean the panel. Do not spray the cleaning agent on the panel itself.

•

The touch panel is sensitive to long-term water exposure and any excess moisture should be wiped off. Do

not apply adhesive materials to the surface of the touch panel. This can cause permanent damage. This

restriction includes stickers, tape and static screen protectors.

Some components may lose short-term memory, that is, engine or transmission adaptive parameters, and

radio presets after a protracted time without battery power.

The use of aftermarket screen protectors is not recommended and may void the warranty of the touch panel.
