OCATION OF THE
R
ECEIVER
The
VR-5000
should be located in a place that allows unobstructed ventilation around the
cabinet. Although the VR-5000 does not produce significant amounts of heat, as with any
electronic device a well-ventilated location will ensure that heat does not build up inside
the cabinet.
Do not place the VR-5000 on top of another heat-generating device, and keep its top
cover free of books, papers, and other objects which might impede ventilation.
If you utilize a computer in your monitoring location, we recommend that the
VR-5000
,
its feedline, and its power cord all be kept as far away from the computer as possible, as the
computer, its monitor, and/or other peripherals may radiate energy which can interfere
with reception. Experimentation with several different locations may be necessary, in or-
der to find the most interference-free location.

Base Station Operation
PA-28 AC Power Adapter Installation
Your VR-5000 is supplied with an AC Power Adapter, model PA-28, which provides the
13.5 Volts (DC) required by the
VR-5000
. We do not recommend any other type of power
adapter for use with this product.
To install the PA-28, first connect the small, round DC output connector on the cable of the
PA-28 to the
DC 13.5V
jack on the rear panel of the
VR-5000
. Then plug the PA-28 into
the AC wall outlet.
When disconnecting the PA-28, it is recommended that you first turn the VR-5000 off,
then unplug the PA-28 from the wall outlet, then unplug the round DC output connector.
When making power connections, always grasp the DC output connector, or the body of
the PA-28, so as to minimize strain on the power cable. Never disconnect the PA-28 by
pulling on either end of the cable, as this may lead to early mechanical failure of the PA-28.
DC Power Supply Connections
A well-regulated 13.5 Volt DC Power Supply may also be used with the VR-5000 , provid-
ing it is capable of supplying 1 Ampere of current continuously. A DC cable is supplied
with your
VR-5000 for connection to a power supply.
When making power connections to a power supply, be absolutely certain to observe the
correct polarity, as serious damage can occur if the connections are reversed.
Connect the wire containing the
White Stripe
to the
Positive
(+) DC output terminal, and
connect the All-Black wire to the Negative (–) DC output terminal. Double-check your
hookup before plugging the DC output connector into the
VR-5000
.
