SAFETY/VOLTAGE SELECTION
WARNINGII!
Please read before applying power
The receiveris normally shipped with the input line voltage
selector switch setto 108-132 VAC for operation in the U.S.
and Canada. If your operating voltage is different than
this, please refer to FIGURE 1 below. The voltage select
switch is located on the rear panel and must be set to the
proper voltage range for your area. In addition, the
proper mains fuse may need to be installed. The unit may
be set to operate over the following voltage ranges: 90-
110 VAC, 108-132 VAC, 180-220 VAC and 216-264 VAC.
Most countries outside the U.S. and Canada use either
220 VAC or 240 VAC line voltage. Please be certain of the
operating voltage before connecting to the mains source.
The receiver will operate on either 50 Hz or 60 Hz line
frequency.
Note: The warranty does not cover damage as a result of
improper voltage selection, or replacement of fuse with
ratings other than those specified.

Antenna groundingis necessary if the unitis connected to
an outdoor antenna. Grounding of the antenna system
is required to protect against static build up and voltage
surges. Refer to section 810-21 of the National Electric
Code, ANSI/NFPA No. 70-1990.
The power cord and antenna lead-in should be discon-
nected ifthe unit is not to be used for an extended period
of time or if threatening weather containing damaging
lightning Is likely.
CAUTION
In accordance with international safety
standards, this instrument is equipped with
a three-wire power cable receptacle. The
unitisshipped with a detachable type three-
wire power cable intended for nominal
115/127 VAC mains supply. When con-
nected to an appropriate power line out-
let, this cable grounds the instrument cabi-
net. For operation of this unit on nominal
220/240 VAC mains supply, use the proper
power cable assembly approved by your
local codes.
For use of this product outside the U. S. A. or
Canada on supply voltages of 220 VAC or
greater, the discharge resistor (4.7 Meg
Ohm) connected from the neutral wire ter-
minal of the AC input receptacle to the
receiver chassis must be removed.
Refer modification to a qualified service
technician.
