The IR Blaster provides control of the subscriber's VCR from the DCT 2000. It consists of a
low-power infrared transmitter attached to a six-foot cord and a mounting bracket. The
mounting bracket is a clear plastic holder with a pad of adhesive tape for installing the
IR Blaster near the VCR IR receiver. A mini-pin connector at the end of the cord connects the
IR Blaster to the DCT 2000.
The IR Blaster functionality is controlled by the interactive program application that is resident
on the DCT 2000. Not all applications support the optional IR Blaster.
Figure 4-1 illustrates the IR transmitter installed in the mounting bracket:

The IR Blaster is automatically activated through the electronic program guide. Individual
VCR codes are broadcast through the out-of-band data channel and are updated periodically as
new codes are added.
The procedure for installing the IR Blaster is described in the following paragraphs.

The IR receiver is not visible on some VCRs. You can locate the receiver using the following
procedure:
Obtain a piece of opaque material, such as a 3- by 5-inch index card.
Use the card to block areas of the VCR where the receiver might be located. Turn the VCR
on and off, while pointing the remote control at the card blocking the VCR. Be sure the
remote control is close to the VCR to reduce reflections the receiver may pick up.
Note the area where the VCR is unresponsive to the remote control. This region contains
the receiver and can be marked by loosely taping the index card to the area.
Because the IR Blaster radiates an area approximately 40 degrees wide, it is not necessary to
be precisely on target with the remote control. Offset the location of the IR Blaster transmitters
from the VCR receiver to reduce interference with operation of the VCR remote control.
