Cleaning Procedures

• Inspecting all mounting brackets and associated mounting screws
for secure and tight mounting.
• Checking for overheated or discolored components.
• Checking for proper (13.8Vdc) vehicular alternator charging.
Vehicular voltage can vary from as low as 10Vdc to as high as
18Vdc without being evident to the operator; however, it can
affect XTVA operation.
In areas of high dust or salt conditions, periodically check the
mechanical operation of the console's battery contacts. If contact
movement requires excessive effort, clean any dust or salt deposits
from the moving parts as described below. Cleaning may be
accomplished by performing the following procedure:
1. Remove the console from the vehicle and place it rightside-up on
a flat working surface. The working surface should offer
protection from scratching to the console's surfaces.
2. Referring to the "Disassembly/Reassembly Procedures" in the
"Corrective Maintenance" section of this manual, disassemble the
unit for cleaning.
3. Using the recommended cleaning agent, clean the external
surfaces of the console and the radio alignment surfaces in the
pocket housing. These surfaces should be cleaned whenever a
periodic visual inspection reveals the presence of excessive dust,
grease, and/or grime.
The only recommended agent for cleaning the internal and
external plastic XTVA surfaces is a 0.5% solution of a mild
dishwashing detergent in water (one teaspoon of detergent per
gallon of water).
The effects of certain chemicals and their vapors can be
!
harmful to some types of plastics. Aerosol sprays, tuner
cleaners, and other such chemicals should be avoided.

4. Should they require cleaning, the internal circuit boards and
components can be cleaned when the console is disassembled for
servicing or repair. The only factory recommended liquid for
cleaning the circuit boards and their components is isopropyl
alcohol (70% by volume). Make sure to avoid applying alcohol to
plastic connector housings on the circuit board. Allow sufficient
time for the circuit board to dry, since alcohol can damage plastic
housings.
Note: When the XTVA is used under adverse marine
conditions, the circuit board must be cleaned of salt
deposits at least twice a year.
Isopropyl alcohol may be applied with a stiff, non-metallic, short-
bristled brush to dislodge embedded or caked-on materials
located in hard-to-reach areas. The brush stroke should direct the
dislodged material out and away from the inside of the console.
