Return For Service Procedures
When returning products to Powerwave, the following procedures will ensure optimum
response.
Obtaining an RMA
A Return Material Authorization (RMA) number must be obtained prior to returning equipment
to the factory for service. Pease contact our Repair Department at 1-714-466-1000 to obtain
this number, or FAX your request to 1-714-466-5800. Failure to obtain this RMA number may
result in delays in receiving repair service.
Repackaging for Shipment
To ensure safe shipment of the unit, it is recommended that the original package designed for
shipping the unit be reused. If it is not available, contact Powerwave’s Customer Service
Department for packing materials.
Remote Control Unit (RCU)
The RCU provides remote control of Powerwave WRHs. It contains an integrated mobile
phone, modem and power supply backup. The RCU is installed in the bottom front of the
cabinet, on top of the PSU as illustrated in Figure 4-1.
The RCU is connected to P130 on either an RCI or FON. A jumper is required between pins 1
and 2 on the RCI if the P130 cable connector is disconnected. If a main power failure occurs,
the unit has a battery with enough capacity for sending a number of alarms.
