SERVICE INFORMATION
1-1. HOW TO CHECK THE CRACKED
CHIP PART
(1) Apply heat to the soldered portions of chip
part using a soldering iron for about 2-3
seconds. |
(2) If the chip part 1$ faulty,it will be broken
or cracked. BE m

When you use the solder flux which is applied
to all pins of the Flat-IC,you can remove it
easily.

about 5 ~ 8 seconds.
(2) Remove the FLAT-IC with tweezers. while
applying the hot air.
Caution:Do not supply the hot air to the chip
parts around the Flat-IC for long time as
as damage may occur to the chip parts
around the Flat -IC.

(WITH IRON WIRE)
(1) Affix. the wire to workbench or solid mounting
point as shown in FIG.G12.
(2) Pull up wire as the solder melts so as to lift

Power Source for the Remote Controller
Ш The Remote Controller is powered by 2 IEC “R6” size
batteries. The life of the batteries is about one year,
however, it depends on the frequency of use. Inspect and
if necessary, replace the batteries once a year.
CAUTION FOR BATTERY REPLACEMENT
e Load the new batteries with their polarities ($ and ©)
aligned correctly.
* Do not apply heat to batteries, or internal short-circuit
may occur.
e if you do not intend to use the Remote Controller for a
long period of time, remove the batteries and store them
in a cool and dry place.
1—7
» Remove spent batteries immediately and dispose of
them.
® Do not use an old and a new batteries together. (Also
never use an alkaline battery with a manganese battery.)
N
Г неа the Programming Sheet with саге. If the
sheet gets dirty or scratched, the bar code reading
may become impossible.
{ «Protect the Remote Controller from strong shocks
and vibration. Keep it away from water and places
with high temperature and humidity.
elf the bar code is traced slowly, it cannot be read
correctly.
e When there is no “Beep” sound, the reading of the
bar code is incomplete. Trace the bar code again.
e When using the Programming Sheet, put it on flat
surface: Reading the bar codes while holding it in
your hand or bending it, may result in incorrect
operation.
e Do not deviate from the bar code, nor stop tracing
halfway.
y
Note:
«The infra-red beam should be transmitted directly at the
Infra-red Remote Control Receiver on the front of the
VTR.
e Direct sunlight may interfere with the beam.
e The lightsensing angle of the Infra-red Remote Control
Receiver in the VTR is about 30° for each side from the
centre.
e The unit should be used within a range of about 7 meters
from the front of the VTR.
Recommendation
After the programming of timer recording(s) is completed,
press the Digital Scanner On/Off Button so that the
indications in the Display disappear, in order to save
battery power.
When the Bar Codes Cannot be Read |
Although the lamp in the tip of the Bar Code Reading
Section lights up:
«No figures appear т the Display
e No beep sounds is heard;
The tip of the Bar Code Reading Section is probably
clogged with dirt. '
Cleaning
1 Remove the cap of the Bar Code Reading Section.
e Remove dirt and dust from the hole of the cap.
