CAUTIONS ON USE
CAUTIONS ON THE SUPPLY
When the power voltage is extremely high or low, it may cause trouble or it may not give
optimum performance. Consult your dealer at that time.
KEEP IN A WELL VENTILATED PLACE
Ventilation holes are provided in the cabinet to prevent the temperature from rising. Do not place the unit in a place badly
ventilated or cover the unit with
materials such as clothes.
VOL-
KEEP WATER OUT
When water of liquid enters the set, the unit. Immediately pull the plug out and contact your dealer.
it becomes dangerous to use
HIGH TEMPERATURE CAUSES TROUBLE
Avoid placing the unit in direct sunshine, near a heating appliance.
WHEN BEHAVIOUR IS ABNORMAL
When any abnormal sound, odour or smoke is generated, push the power switch off, pull the power plug out from the socket and contact your dealer.
CAUTIONS
TREATING THE SURFACE
Do not wipe the surface of the
set using volatile liquids such as benzine or thinners, or any
chemically treated cloth; do not
apply insecticide. It may damage the surface or cause peeling-off of the paint. When a vinyl product is kept in contact with
the surface for a long time,
stains may occur.
BE CAREFUL OF MAGNETISM
Do not bring materials which generate magnetism, such as a magnet, printers, floppy discs, or transformers etc. nearby: the set may be affected by magnetism, causing
colour
disturbance or
picture distortion etc.

2. Advance the contrast and brightness controls fully clockwise.
3. If no picture appears check the video drive and source connections particularly green for sync on green models or composite sync if there is a separate line. No picture will appear without the sync signal.
4. When a display appears note the stability of the displayed image. If it is not stable or it is displayed from centre, switch off the mains supply
and
remove outer plastic case only by removing four
screws from the rear panel and two screws from the centre portion. It may be convenient to remove and replace signal and power cables at this stage, since they pass through the rear cover. See

5. Power up and adjust (if necessary) the horizontal hold control with plastic trimmer (Fig.ll). Note that it is important that a plastic
trimmer is used. Otherwise the adjustment could result in a short circuit and breakdown of display.

.
6. Adjust vertical hold control (if necessary) with plastic trimmer.
7. Either of the two previous controls should stabilize the picture.
If not, call the service engineer.
8. With a stable picture, note the size and its position of the picture. Any adjustment shoud be made in the following sequence.

9. With the previous adjustments complete YOU shoud now have a stable picture correctly
centred.
Check the left and right hand edges of
the picture for clarity. If any corruption is present, it is
necessary to adjust the horizontal phase until both extremities are
clear. If adjustment is necessary,
the horizontal centre and size
may need further adjustment.
10. Display a picture that contains vertical lines at both right hand and left hands of the screen. If necessary, adjust the pin cushion control to make the lines straight.
11. Display a picture that contains a multiplicity of horizontal lines with constant spacing. If the lines are not displayed with equal spacings adjust the vertical linearity. If this adjustment is necessary, some readjustment of the vertical centre and size may be required.
12. Display a picture that contains a large white area and check that the displayed image is white. If it is not, an unqualified engineer shoud not attempt to adjust the
colour
drives or background to compensate. A qualified engineer must first determine that the black level pedestal is correctly positioned before any such adjustment is considered. This work involves further dismantlement of the chassis.

13. If in doubt or experiencing difficulty with the adjustments detailed, contact the supplier of the equipment.

14. In all of the above adjustments, ensure that the viewable displayed image does not exceed a displayed field of 380 mm X
270
mm.
Finally, power down and replace covers and centre case portion first.
Turn brightness and contrast controls to their normal operating
positions.
