INSTALLATION
Connecting Optional
Accessory
Refer to Figure 14
1. To connect an external audio source (cassette player, stereo
system, VCR, TV, etc. with low level audio output) to the
IM-3204 master station, locate the CD/TAPE input on the
lower center of the master station's main circuit board.
2. Connect an RCA™ phono type plug to the shielded audio
cable coming from the external audio source. Follow the
phono plug manufacturer's instructions when connecting to
cable.
3. Insert the phono plug into the CD/TAPE jack on the master
station main circuit board.
Securing the Master Station
Panel
Refer to Figure 15
1. Inspect all wiring connections at the master and remote
stations.
2. Make sure the antenna connection plug is secure.
3. Dress all remote station wires flat against the back of the
rough-in while the master panel is raised into final position.
NOTE: WHEN RAISING THE MASTER PANEL TO ITS FINAL
LOCATION, DO IT SLOWLY. BE CAREFUL NOT TO HIT OR
DAMAGE ANY OF THE CIRCUIT BOARDS OR WIRING.
4. Position the master station panel over the rough-in frame,
and align screw holes in the master panel with mounting
brackets.
5. Secure the master station panel to rough-in mounting
brackets with the two (2) screws provided.
NOTE: The mounting screws will pierce the wall surface behind
the mounting brackets. If the wall surface is hard, a clearance
hole must be drilled behind the mounting brackets before

securing the master station panel.

Powering Up the System

Once all connections throughout the system have been
checked, power can be applied to the master station
transformer.
1. Apply power to the master station by turning on the circuit
breaker that supplies power to the power transformer in the
IR-103 rough-in frame.
2. When the power is first applied, and the radio is turned on,
the LCD display will flash until the radio is tuned. Please
refer to the operational checkout section of this manual for
additional information.
