Inspection - Exterior
Inspect the outside of the VCM-D1 for damage, wear, and missing parts. A
device that appears to have been dropped or otherwise abused should be checked
thoroughly to verify correct operation and performance. If this damage is suspected,
please return the unit to the factory for repair – no user serviceable parts inside.
Cleaning Procedure - Exterior
1. Remove loose dust on the outside of the VCM-D1 with a lint free cloth.
2. Remove remaining dirt with a lint free cloth dampened in a general purpose
detergent-and-water solution. Do not use abrasive cleaners.
To prevent getting moisture inside the driver during external cleaning, use only
enough liquid to dampen the cloth or applicator.
Cleaning Procedure – Interior
1. Blow off dust on the exterior with dry, low pressure, deionized air (approximately 9 psi).
2. Remove any remaining dust with a lint free cloth dampened in isopropyl alcohol (75%
solution) and rinse with warm deionized water. (A cotton-tipped applicator is useful for
cleaning in narrow spaces.)
BE SURE THE LINE CORD IS DISCONNECTED FROM THE LINE
VOLTAGE POWER SOURCE. UNPLUG THE LINE CORD FROM THE AC
MODULE CONNECTOR LOCATED AT THE REAR PANEL.
3. Gain access to the interior of the unit by removing the four 6-32 flat head screws that
hold the top cover in place.
4. Once the line voltage has been disconnected, remove the top cover by pulling straight up.
Lift off alignment plate to reveal interior of the housing. Use care when removing the
plate not to twist circuit boards.
5. Blow off dust that is visible from the interior with dry, low pressure, deionized air
(approximately 9 psi).
6. Do not use any liquids or cleaning agents internal to housing or on circuit boards or any
components.
7. Replace alignment plate and top cover by reversing the procedure used to remove them
and replace the four screws. Do not use excessive force when re-tightening screws.
CAUTION
If, after doing steps 1 and 2 below, the device is clean upon
inspection, skip the remaining steps.
WARNING
To avoid injury or death, unplug the line cord from the
line voltage power source before continuing.
