XX214-00 Surveyor HD Network Dome
Care and Cleaning of Metallized Domes
1. Always handle the lower dome by the flange and avoid touching the
inside surface, as acid in a fingerprint can etch the internal coating.
Use the recommended cleaning procedure in Step 4.
2. If dust or dirt accumulates in the lower dome's interior, remove it with
clean, dry pressurized air.
3. If spots, streaks or stains appear on the interior, they can be removed
by rinsing with clean water and drying with clean, dry pressurized air.
Do not rub the inner surface.
Caution
Rubbing the inner surface of metallized lower domes can cause permanent
scratches that may render the dome unusable.
4. If cleaning of the inner surface is necessary, use a wick. Make a wick
by rolling a section of soft microwave-safe (aluminum free) paper
towel into a tightly wound tube and tear it in half. Moisten the torn
edge of the wick with an approximate solution of 50% isopropyl
alcohol and 50% water. Hold the Lower Dome upside down and
gently wipe the inner surface from the inside to the outer edge. Use a
new wick for each 2 passes over the dome.
5. Clean the lower dome's exterior with any soft, nonabrasive cleaning
cloth and a cleaning agent suitable for acrylic plastic. Either liquid or
spray cleaner (wax suitable for fine furniture) is acceptable.
Fuse Replacement
The Surveyor HD has two resettable 1.35 A, 72 V fuse. Be sure to use a fuse
of the same value if it is necessary to replace the fuse.
