Sony MRD-D1 - Manual (Page 6)

Preparation for Use
Before installing your MRD-Dl, please read the following brief
discussion of its parts and what they do:
Modulator Unit
The modulator unit accepts the video input from your Sony DSS
receiver and one other video device of your choosing (VCR, laserdisc
player, etc.) and creates an "in-house" television channel for them. The
unit also accepts the input from an off-air antenna or cable service and
provides some amplification of the signal. The outputs from the
modulator unit can be connected to up to five TVs: two located within
30 ft. of the unit, and three located within 100 ft. of the unit. When
connected to remote TVs, a Sony IR target EAC-Tl must be used in
order to use your remote control.
Power Supply
The MRD-Dl is designed to operate from a 12 V AC power source. The
power supply provided with your system will make the necessary
voltage conversions when connected to 110 V AC, 60 Hz power.
Under no circumstances should you substitute the power supply
provided with MRD-Dl.
IR Emitters
There are two IR emitters provided with MRD-Dl. The IR emitters
connect to the modulator unit and are to be placed over the IR receiver
located on the video sources. One emitter is provided for each source.
IR Target
One IR target is provided with MRD-Dl. The IR target is to be installed
in a remote viewing room and is connected to the modulator urrit via a
75-ohm coaxial cable. This IR target must be exposed so you can point
your remote control at it.
