Opening the Housing
Tools required:
• 3/8-inch socket
• 6-inch extension
To open the housing, loosen the four cover screws while supporting the housing so it
does not fall. (The cover screws are retained in the housing.) The front of the unit is heavy
but it is attached to the rear housing with a pivot hinge to allow ease of service. If the unit
requires service, replace the front housing, amplifier, and power supply (if equipped) as an
entire unit.
