sources such as radiators,
heat registers, stoves, or
other apparatus (including
amplifiers) that produce
heat.
9. Do not defeat the safety
purpose of the polarized
or grounding-type plug.
A polarized plug has two
blades with one wider than
the other. A groundingtype plug has two blades
and a third grounding
prong. The wide blade or
the third prong is provided

where they exit from the
apparatus.
11. Only use attachments/
accessories specified by the
manufacturer.
12. Use only with a cart,
stand, tripod, bracket or
table specified by the
manufacturer, or sold with
the apparatus. When a cart
is used, use caution when
moving the cart/apparatus
combination to avoid injury
from tip-over.
13. Unplug this apparatus
during lighting storms
or when unused for long
periods of time.
14. Refer all servicing to
qualified service personnel.
Servicing is required when
the apparatus has been
damaged in any way, such
as power-supply cord or

will glow blue when the ISR is
receiving power from the CAT 885.
2. A/B IR INDICATORS: These lights
glow when the corresponding
microphone (set to channel A or
B) is turned on and transmitting.
A steady light indicates a strong
signal.

to the CAT 885 amplifier.
4. IR EXPANSION: Connect up to
three passive IR sensors (IR-SR70F)
to this connection for larger
classrooms. For more than one
additional sensor a 3-way coax
splitter is required (HS3).

SECTION 2:
SET-UP & USE
1. LOCATION OF THE AMPLIFIER
First, find a suitable location to set-up the amplifier. It is best to put the amplifier
in a stable location near the other equipment to be used. If this is not possible,
an optional Lightspeed wall shelf can be installed.
3. Optional
Accessories
1. Overview 2. Setup & Use
Media Cabinet Set-up
Avoid Separated Set-ups
Components should be located
together. Wires should be routed
directly back to the amplifier.
Wall-mount Set-up
The optional Lightspeed wall shelf
(part #AC-800WB) is specifically
designed to support the CAT 885.
14
2. IR SENSOR/RECEIVER (ISR) INSTALLATION
Next, find a suitable location for the ISR. Poor location will cause substandard
performance of the CAT 885 Classroom Audio System. The ISR should be as
high as possible in the room – the ceiling is the best location, centered along the
longest wall in the room. When possible, use a conduit to protect the wires (not
included). Poor choices for placement are corners, on walls at heights lower than
7 feet (2 meters), or in places where the line of sight from the ISR to the receiver
is or could be obstructed.
