SAFETY/VOLTAGE SELECTION

WARNING!!!

Please read before applying power

The receiver is normally shipped with the input line voltage

selector switch set to 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 grounding is necessary if the unit is 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 if the 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

unit is shipped 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.
