NOTE: It is recommended that you
use VCIR-CFL's with a ZPR68-10
only
when manual volume control is wanted
in 2 or more rooms within a zone.
Add resistor in series with Status

CAUTION:
Stereo receivers usually have two sets of
speaker terminals, "A" and "B". Be sure all speakers
connected to both "A" and "B" are taken into
consideration when paralleling speakers, so that the
amplifiers are not loaded by an impedance that is lower
than that specified by the manufacturer.

Important:
Be sure to orient the unit so that the IR Receiver Photo Diode (the larger window) is
below
the knob as illustrated in
Fig. 1
. Since hand operated wall units are typically mounted 4 feet above
the floor, this orientation prevents the knob from blocking the IR signal when sent from a sitting position.
3
.
The decorator-style
plastic insert plate
(supplied) is available in either white or ivory. It mounts with
four plastic tabs and light adhesive, allowing it to be removed for refinishing to other colors, if desired.
Remove by pressing on the tips of the tabs while pulling outward on the insert plate. Be sure to remove
the push-on knob first. Refer to
Fig. 6
.
Also, be sure not to paint over the two IR circular windows!
Cover with masking
tape before painting.
4. Mount the unit using
the hardware provided,
referring to
Fig. 6
. The
VCIR-CFL is attached
to wall J-boxes using
the two 6-32 pan-head
screws supplied. Slots
are provided in the
metal mounting bracket
so that adjustments to
vertical alignment can
be made.
CAUTION:
THE ELECTRI-
CAL JUNCTION BOX, IN
WHICH THE VCIR-CFL IS
MOUNTED, MUST BE
DEDICATED TO LOW
VOLTAGE A/V SYSTEM
APPLICATIONS. MAKE
SURE THAT NO AC
MAINS WIRING PASSES
THROUGH OR TERMI-
NATES IN THIS BOX!
Com-
binations of VCIR-CFL’s and
other low voltage devices,
however, may be mounted
together in multi-gang boxes.
