Notes
• The TV/VIDEO button selects the TV’s input source (either aerial in or line in). The

button does not control this VCR.

• With normal use, the batteries should last about three to six months.
• If you do not use the remote commander for an extended period of time, remove

the batteries to avoid possible damage from battery leakage.

• Do not use a new battery with an old one.
• Do not use different types of batteries.

The remote commander is preprogrammed to control non-Sony TVs. If your
TV is listed in the table below, set the appropriate manufacturer’s code
number.

Set 

TV/VIDEO

 at the top of the remote commander to

.

Hold down ?/1, and enter your TV’s code number(s) using the
programme number buttons. Then release ?/1.

Now you can use the ?/1, VOL +/–, PROG +/–, programme number
buttons, ? (ten’s digit) and TV/VIDEO buttons to control your TV. You
can also use the buttons marked with a dot (•) to control a Sony TV. To
control the VCR, reset 

TV/VIDEO

 to

.

If more than one code number is listed, try entering them one at a time until
you find the one that works with your TV.

Getting Started

Notes
• If the TV uses a different remote control system from the one programmed to work

with the VCR, you cannot control your TV with the remote commander.

• You may not be able to use some buttons to control non-Sony TVs due to the remote

commander’s signal limitations.

• If you enter a new code number, the code number previously entered will be erased.
• When you replace the batteries of the remote commander, the code number may

automatically reset to 01 (Sony). If your TV is not a Sony, it is recommended to
manually set the appropriate code number every time you replace the batteries.

• If you set your TV’s code number correctly while the TV is turned on, the TV turns

off automatically.

Getting Started

Disconnect the aerial cable from your TV
and connect it to AERIAL IN on the rear
panel of the VCR.

Connect AERIAL OUT of the VCR and
the aerial input of your TV using the
supplied aerial cable.

Connect the mains lead to the mains.

If the 3-pin plug does not fit into the mains outlet, detach the plug
by loosening the screw, then use the 2-pin plug inside.

Connect the aerial to your VCR and TV as shown below to watch TV
programmes and VCR pictures on your TV. In addition, if your TV has
audio/video (A/V) input jacks, we recommend you connect the VCR to
your TV using an audio/video cable to get a better picture and sound.

The VCR signal is output through this channel to the TV.

Turn on your TV and select a programme position for the VCR picture.
This channel will now be referred to as the video channel.
Some TVs reserve a programme position, such as “0”, for a VCR. In
this case, select the reserved programme position for the VCR
picture. Refer to your TV’s instruction manual for details.

Press RF CHANNEL.
The TV system indicator appears in the display window.

Getting Started

Tune the TV to the same channel as
shown in the display window so that
the picture on the right appears on the
TV screen.

Refer to your TV manual for tuning
instructions.

If you select the wrong TV system in step 4, the picture may not
appear. Select the appropriate TV system and tune the TV again.

If the picture does not appear clearly, see “To obtain a clear picture
from the VCR” below.

Press RF CHANNEL.

You have now tuned your TV to the VCR. From now on, whenever
you want to play a tape, set the TV to the video channel.

If the picture does not appear clearly in step 5 above, first go to step 6 to
finish this procedure once. Then start from step 2. After pressing RF
CHANNEL twice in step 2 to display the RF channel, press the PROGRAM
+/– buttons on the VCR so that another RF channel appears. Then tune the
TV to the new RF channel until a clear picture appears.

To set another RF channel number on the VCR, select a channel number that
does not receive a broadcast signal in your area and is clear of interference
from other channels.

If you cannot obtain a clear picture after performing this procedure, we
recommend you connect the VCR and TV using the audio/video cable (see
“To a TV that has audio/video input jacks” on page 9). If the same symptom
persists, consult your nearest Sony dealer.

Tips
• The PROGRAM +/– buttons are also used for adjusting the tracking. See pages 52

and 59 for details.

• The RF CH button is used for the One Touch Tuning function. For details, see page

12.

Note
• If you set the wrong TV system, you may have no sound or sound may be distorted

(noisy sound).

First, we recommend that you preset the receivable channels in your area
using the One Touch Tuning function or AUTO PRESET in the TUNER
PRESET menu. Then, if some channels cannot be preset automatically, set
them manually. If there are any unwanted channels among the preset ones,
you can disable the channels.

If you live in the area where various TV systems coexist, and have channels
that do not match the TV system you selected in automatic presetting, reset
the TV system for those channels (see “Resetting the TV system” on page
17). If the channels do not match the TV system, the sound may be distorted
or noisy, or the colour TV programme may become black and white, etc.

Press and hold RF CHANNEL on the VCR for more than three
seconds.

The VCR starts presetting the channels.

The WAIT indicator goes off when all receivable channels are preset.

Set the TV to the video channel and press the PROGRAM +/– buttons on the
VCR. If the TV screen changes to a different programme each time you press
the PROGRAM +/– buttons, the channels are preset correctly.

If the sound is distorted or noisy, the VCR is set to a TV system different
from your area’s system. Select the correct TV system and preset channels
using the TUNER PRESET menu as shown on the next page.

Tips
• To stop the One Touch Tuning function, press RF CHANNEL or s (stop) on the

VCR during the setting.

• The PROGRAM +/– buttons are also used for adjusting the tracking. See pages 52

and 59 for details.
