Section 13 – Care & Maintenance
Front Panel
Cleaning
Do not use any solvents or abrasive cleaners on
the front panel. Do not spray cleaner directly onto
the front panel. Apply a small amount of com-
puter cleaner to a soft towel first. Clean the panel
with the moistened towel. Do not spray or apply
the cleaner directly to the DPC. Do not allow any
liquid to collect around the AC power switch.
Display
Do not use a sharp object on the display.
Control Keys
Use your finger to press the control keys. Do not
use sharp objects on the keys. If your hands are
greasy or contaminated with dirt, use a soft ob-
ject like a pencil eraser to push the keys.
Rear Panel
Connectors
The rear panel System Input and Status Output
each have a pair of 4-40 threaded nuts to secure
the connectors. Do not overtighten them
AC Power Cord
The AC power cord should be kept in good condi-
tion and free from any cuts. The AC plug should
be straight with no bent prongs.
Grounding Stud
The rear chassis earth ground connection (see Fig-
ures 2–5 and 3–3) is a 10–24 x 1/2" threaded stud.
Do not overtighten the nut.
Chassis
Side Ventilation Slots
Keep the two side ventilation slots free from ob-
structions. If excessive dust or dirt collects on the
slots, wipe or vacuum them clean. Do not use com-
pressed air to clean them as this may force the dirt
inside the chassis. The right hand slot (when
viewed from the front) is the air intake and the
left hand side is the exhaust. Allow at least 2 inches
(5 cm) on either side for air circulation as shown
in Figure 13–1.
