MAINTENANCE AND TROUBLESHOOTING

Cleaning and Periodic Maintenance

The PM 101 requires no periodic maintenance. Refer to
Section 5 of this manual for a Performance Check if
performance is in doubt. Operating circumstances will
determine when the following cleaning procedure should
be followed.
Exterior. Dust the Personality Module with a soft brush
or cloth. Dirt should be removed with a cloth dampened in
a mild solution of detergent and water.
�
DO NOT use chemical cleaning agents on the pod
covers as they may damage the plastic. In particular,
avoid solutions containing acetone, benzene, xylene
or other organic solvents.
DO NOT use a cloth which is too damp or touch the
connectors with the cloth.
Interior. Use a jet of low pressure air to remove dust
from the interior of the pod and the circuit boards. A soft
brush may be required. After soldering, or when otherwise
required, use isopropyl alcohol with a soft cloth or cotton
swab to remove flux, resin or dirt.
