1. WARNING
To prevent the risk of fire, smoke, orelectrical shock and toensure safe operation, please be
sure tofollowthe safetyguidelines below.
1. Atplaces where special caution isrequired, the necessarysafety
precautions are clearlylabeled or printed, for example, on the
cabinet, or on the part concerned. Please follow these safety
precautions, and also those listed inthe Owner's Manual.
2. Parts which have a ;mark inthe circuitdiagram or inthe parts
list are essential for safety. When replacing these parts, be sure to
use onlythe specified parts.
3. Use the specified types for internal wiring (double-insulated
wiring, etc.).
4. When replacing parts on the AC primaryside (power transformer,
electricswitch, electrical cord, noise-prevention condenser, etc.),
wind the lead wire and secure itbysoldering.
5. Donot let the wiring come into contact with heat-emitting devices
(fuse resistor, radiator plate, etc.).
6. When replacing the wiring, make sure that itisnot incontact with
3

the unfinished or rough edge of apart.
7. When replacing the power cord (except for the plug-intype), tug it
from various directions to confirm that itdoes not slipout of
place.
8. Spacing
Ifsoldering was done on the AC primarycircuit, confirm that the
interval between the soldered terminalsor between the terminal
and surrounding metallicparts isat least the minimum required
(between the primarycircuitand the chassis: at least 6.5mm;
between primarycircuitterminals: at least 4.0mm; between
primarycircuitterminalsand secondarycircuitterminals: at least
6.5mm.).
2. SAFETY PRECAUTION
2.1. SafetyPrecaution
1. Before servicing, unplug the power cord to prevent an electric
shock.
2. When replacing parts, use onlythe manufacturer’srecommended
components for safety.
3. Check the condition of the power cord. Replace ifwear or damage
isevident.
4. After servicing, be sure to restore the lead dress, insulation
barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, be sure
to make the following insulation resistance test to prevent the
customer from being exposed to ashock hazard.
2.2. Insulation Resistance Test
1. Unplug the power cord and short the prongs of the plug with a
jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with an ohmmeter between the
jumpered AC plug and each exposed metal cabinet part, such as
screw heads, connectors, control shafts, handlebrackets, etc.
4

Measurements shouldrange from 4MOhm to infinityfor all
exposed parts.

5. Initial Setting
The following procedure resets all programmable settings, functions and memories totheir
initialized(factory-preset) status.
Use this procedure if the buttons, keys, etc. malfunction, orwhenyou wishtoreset the
memories and functions.
1. Turn off the POWERbutton.
2. Whilepressing the INITIALkeyat the same time, turn the POWER
button on again.
Or, you canpress the INITIALkeywhile the MODE SETbutton is pressed.
