General Maintenance and Cleaning

Dirt or dust may be removed from units with a soft cloth. Fresh water-moistened cloth
may be used to remove stubborn dirt. DO NOT use any commercial cleaning agents
to clean any unit. They can remove paint and markings.
Remote Alarm Panel VR-7017: Wipe the LCD of VR-7017 carefully to prevent
scratching, using tissue paper and an LCD cleaner. To remove dirt or salt deposits,
use an LCD cleaner, wiping slowly with tissue paper so as to dissolve the dirt or salt.
Change paper frequently so the salt or dirt will not scratch the LCD. Do not use sol-
vents such as thinner, acetone or benzene for cleaning. Also, do not use degreaser or
anti-fog solution, as they can strip the coating from the LCD.
Waterproof Microphone VR-7012W: The watertight integrity of the microphone will
be compromised if water contacts the ventilation sheet behind the MIC cover.
Fixed DRU VR-7021: Check the adhesive (silicone sealant) on the mounting bolt, nut
and cable gland to confirm that the adhesive is not deteriorated, every three to six
months. When deteriorated, reapply the adhesive. If severely deteriorated, remove all
adhesive before reapplying. Deteriorated adhesive may cause water leakage or elec-
trolytic corrosion.
WARNING NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to coating
or plastic parts of the equipment.
Those items contain organic solvents
that can damage coating and plastic
parts, especially plastic connectors.
