Follow the instructions carefully, which will allow
and give many years of serivce.

1. No scratch and melting shall be made to covered lead-wires of an

a.c. primary circuit including mains leads.

No illeqihility shall he uiven to the specification plate, the cau-

tion labels, the fuse labels and others.

When, on pattern sides of circuit boards, additional repair-parts

have been male up, the parts shall be firmly glued to circuit

boards or other components, unless the parts can be attached

firmly.

. The following matters shall be maintained as they are, when
repairing.
ll Soldering of lead-Wire ends

Care should be taken of the space distance in an ac priA
mary circuit as well as soldering.

Wiring and holding of Ieadwires with Wire-clips and binders

Materials of lead-wares

' 2.9.; For UL models, lead-wires to be used shall be 2197

proved or accepted by the UL,

Location of all kinds of insulators

Setting of voltage selector sWitch

' Set the Voltage Selector Switch to 240V, 220V] or 120V,
According to your Local Voltage.

After repaired, the insulation resistance or leakage current shall

be measured with 500 2 5V D.C and shall be not less than 1M5).

. General instructions for mechanism repair

the user to optimise the products performance

fl The heads, capstan and punch roller shall be Cleaned ol good
quality alcohol after repaired, because dirty heads shall cause
distorted sounds while dirty capstan and pinch roller shall
occur wow/flutter and takerup lauli

Lubricants been stained the surfaces of transmitting portion
of the belts, idlers, capstan and pinch roller shall be removed,
because slippery and faulty tape travel shall be caused

when oiling, only one or two drops shall be applied so as
not to run over and be dispersed Note should be taken of the
metal fitting for the capstan and rotating portions of the
idlers and pinch roller, especially,

Erllllgs and poly slider washers shall be replaced With new
ones, if once those have been removed 7 No TE'UIlllaYlOn
due to unreliability,

Regular sparerparts shall always be used for repair, because
using irregular parts and tampering With ihe producls shall
cause deterioration, muliunction and damage.

C-MOS IC handling precaution

The C-MOS lC's construction makes this part susceptible to damage

by static elecrrICltv and so take sufficient care in regard to follow-

ing articles,

1. Need to be put on conductive sheet, to be put in a metallic box
and to be wrapped by aluminium foil for transportation and
deposit.

2. To use solder iron less than 40W (less than 260a Ci of power
consumption for soldering. But do not overheat more than 10
second.

3. Do not perlorrn a conductiVIty test with a tester, etc. Refer To
the circuit voltages of each part.

4. The ICs on the electrical parts which are indicated by an O-
MOS levmbol mark I G) l.
