GENERAL
GENERAL
Operate on 120 volt, 60Hz AC. DO NOT ATTEMPT TO
OPERATE YOUR VCR ON HIGHER VOLTAGES, 50 CYCLES
OR DC. The power cord has a polarized plug with one regular
blade and one wide blade. It will fit into the standard electrical
outlet ONLY ONE WAY. If the blades will not enter your
outlet, try reversing the plug. If it will not enter either way, your
outlet is non-standard. A new outlet should be installed by a
qualified electrician. DO NOT DEFEAT THE SAFETY
PURPOSE OF THE POLARIZED PLUG.
Keep the recorder and video cassette away from strong magnetic
fields.
After playing a video cassette, remove it from the recorder. DO
NOT move the recorder with a cassette in the compartment.
If a cassette has been subjected to cold temperature, allow it to
warm to room temperature before recording or playback.
To disconnect the cord, pull out by the plug. Never pull on the
cord.
Operate the recorder only on a level, horizontal surface. DO
DO NOT install the recorder on an inclined surface.
On the top and bottom of this VCR are slots which permit air
flow. DO NOT ENCLOSE THE CABINET OR OTHERWISE
OBSTRUCT VENTILATION AT THE TOP OR BOTTOM.
DO NOT install the recorder in a location near heat sources, or
in a place subject to direct sunlight, dust, mechanical vibration,
shock, or dampness. Moisture may cause damage to tape and
recorder heads.
When you are going away on vacation, or don’t plan to use the
recorder and TV, unplug them from the wall outlet to protect
against possible damage from lightning or power system surges.
If connected to an outdoor antenna, disconnect the lead-in from
the back of the unit.
Should any liquid spill into, or solid object fall onto the cabinet,
unplug the recorder and have it checked by a distributor-
approved SONY Service Center before attempting to operate it.
To clean the cabinet panels and controls, use a dry or slightly
damp soft cloth. If a damp cloth is used, moisten it with a MILD
detergent. DO NOT use solvents, such as alcohol or benzine
which may damage the finish.
Save the shipping carton and packing material. They will come in
handy if you ever have to ship your recorder. For maximum
protection, re-pack the recorder as it was originally shipped from
the factory.
NOTE ON OPERATING POWER VOLTAGE
AND FREQUENCY
The SL-5000 video cassette recorder comes in three models to suit
the local operating power voltage and frequency.
Type 1: Model available in the U.S.A., Canada, Central and
South America (except the Chile), etc.
This unit operates on 120 V ac, 60 Hz.
Type 2: PX model
This unit operates on 120 V ac, 50/60 Hz. Before con-
necting the unit to the power source, set the TIMER
switch at the rear to the appropriate position, as indi-
cated below.
Model available in other countries.
This unit operates on 220 V ac, 50/60 Hz. Before con-
necting the unit to the power source, set the TIMER
switch at the rear to the appropriate position.
50 Hz 60 Hz
TIMER
CAUTION FOR THE CUSTOMER WHO HAS THE MODEL OF
TYPE 1 OR TYPE 2:

Connecting a conventional TV receiver
Once the connections shown below have been made, the antenna
TV signals, as well as the signal from the recorder, will be fed to the
TV and you can view TV programs in the usual way.
@ Use an optional RFC-8 extension cable (available in the U.S.A.
and Canada), 8 m (25 ft) long, if the supplied 75-ohm coaxial cable is
not long enough.
75-ohm coaxial cable (supplied)
If your TV receiver is not equipped with an F-type VHF antenna

Caution
Connections between the recorder VHF OUT connector and the
antenna terminals of a TV receiver should be made only as shown
in these instructions. Failure to do so may result in operation that
violates the regulations of the Federal Communications Commis-
sion regarding the use and operation of rf devices.
Never connect the output of the recorder to an antenna or make
simultaneous (parallel) antenna and recorder connections at the
antenna terminals of your receiver.
POWER CONNECTION
After the antenna and TV receiver have been connected, connect
the ac power cord of the recorder to a wall outlet.
CAPTIONS + PCM switch
Captioned TV programs* can be recorded and played back with
this recorder when a decoder unit or a TV designed to receive clos-
ed caption signals is connected. PCM recording and playback can
also be made when a PCM digital audio processor, such as the
Sony PCM-10, is connected. For captioned program or PCM
playback, set the CAPTIONS + PCM switch under the cover to the
left position.
For details, see the instruction manual of the decoder, the TV or the
audio processor.
