Service

7.1 General

This section describes suggested maintenance and troubleshooting procedures. The
troubleshooting procedure is divided into two sections. The first section deals with basic
operation and connection of the equipment. The second section requires opening the unit
and using the LED indicators and a simple multimeter to troubleshoot the unit down to the
module level. Only a qualified electronic technician should attempt this level of
troubleshooting.

7.2 Cleaning

The exterior of the power source may be cleaned with a cloth dampened with a mild
detergent and wrung out. Disconnect mains power to the source before cleaning. Do not
spray water or other cleaning agents directly on the power source.
