Rack Mounting
The CR88 receiver can be installed into a standard 19” rack for transport or permanent installation using the included rack ears. Follow the simple steps below to
mount the CR88:
Attach the included rack ears by sliding each rack
ear into the groove on either side of the CR88 until
they lock into place, and the receiver flush with the
front panel.
Position the CR88 receiver into an
available rack space and slide in
until the rack ears are touching the
rails of the rack case and are aligned
with the rack rail holes.
Mount the receiver into the rack using the appropriate size rack screws (not included). To ensure equal tension and balance when installing the receiver, you should
secure screws in a crisscross pattern of opposite corners: top left -> bottom right ->
top right -> bottom left.
In order to mount two CR88 receivers in one rack space, the system
includes a center connection piece.
Slide the center connection piece
into the groove of each receiver and
attach the short rack ears to each
receiver. Mount the receivers into
the rack using the crisscross pattern
described above.

Troubleshooting
Issue
Solutions
Make sure that the transmitter and receiver are both
powered on.
Ensure the transmitter’s batteries are installed correctly.
Check that the transmitter is not muted.
Confirm that the CR88 adaptor is correctly connected and
plugged into an electrical outlet.
Turn on the CR88 receiver.
No Audio
Make sure the CR88 audio output connections are securely connected.
Ensure that the receiver and transmitter are in line of
sight with one another.
Check the receiver and audio input device level controls.
Ensure that the transmitter and receiver are set to the
same operating channel. If unsure, reset the channel by
performing an IR set.
The receiver output level or audio input device level may
be too high.
Distorted Audio
Check the transmitters batteries, and replace if low.
The input gain on the transmitter (CB88) or audio source
level may be too high.
The transmitter may be too far away from the receiver.
Move it closer to the receiver, or reposition the antennas.
Audio Dropout
Remove any sources that may cause RF interference such
as cell phones, cordless phones, lighting equipment, computers, metal structures, etc.
Receiver will not
power on
Check the adaptor to ensure it is properly connected and
plugged into an outlet providing power.
Transmitter will not
power on (LED lights
RED)
Replace the transmitter batteries.
Unwanted noise or
interference
If using multiple systems, make sure none of the systems
are operating on the same channel. If the problem persists, change one or all of the systems channels.
