- Troubleshooting / Maintenance -
If trouble occurs
When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction.
If such a problem occurs, do the following:
Caution:
This operation will erase all data stored in memory including clock, timer settings, tuner preset, and CD programme.
After the above operation, interval span setting for AM will be returned to 9 kHz (50 kHz for FM) automatically.
1 Set the unit to the stand-by mode and turn the power on
again.
2 If the unit is not restored in step 1, unplug and plug in the
unit, and then turn the power on.
3 If neither step 1 nor 2 restores the unit, do the following:
Press the ON/STAND-BY button to enter the power stand-by mode. Unplug the AC power lead from the AC INPUT socket on the unit. Whilst pressing down the MEMORY/SET button and the button, plug the AC power lead into the AC INPUT socket on the unit.

Remote Control
Battery installation
1 Remove the battery cover. 2 Insert the batteries according to the direction indicated in
the battery compartment.
When inserting or removing the batteries, push them towards the
battery terminals.
3 Replace the cover.
Precautions for battery use:
Replace all old batteries with new ones at the same time.
Do not mix old and new batteries.
Remove the batteries if the unit will not be used for long per iods of time. This will prevent potential damage due to battery leak­age.
Caution:
Do not use rechargeable batteries (nickel-cadmium battery, etc.).
Installing the batteries incorrectly may cause the unit to malfunc­tion.
Notes concerning use:
Replace the batteries if the operating distance is reduced or if the operation becomes erratic. Purchase 2 "AAA" size batteries (UM­4, R03, HP-16 or similar).
Periodically clean the transmitter on the remote control and the sensor on the unit with a soft cloth.
Exposing the sensor on the unit to strong light may interfere with operation. Change the lighting or the direction of the unit.
Keep the remote control away from moisture, heat, shock, and vibrations.

Setting the AC voltage selector
Check the setting of the AC voltage selector located on the rear panel before plugging the unit into a wall soc ket. If necessary, adjust the selector to correspond to the AC power voltage used in your area.
Turn the selector with a screwdriver until the appropriate volt­age number appears in the window (110 V, 127 V, 220 V or 230 V
- 240 V AC).
Connecting the AC power lead
After checking all the connections have been made correctly, connect the AC power lead to the AC power input socket, then into the wall socket.

Notes:
Unplug the AC power lead from the wall socket if the unit will not be in use for a prolonged period of time.
Never use a power lead other than the one supplied. Use of a power lead other than the one supplied may cause an elec­tric shock or fire.
AC Plug Adaptor
In areas (or countries) where a wall socket as shown in illustration is used, connect the unit using the AC plug adaptor supplied with the unit, as illustrated. The AC plug adaptor is not included in areas where the wall socket and AC power plug can be directly connected (see illustration ).

XL-1000W
Setting the AM/FM interval
The International Telecommunication Union ( ITU) has established that member countries should maintain either a 10 kHz or 9 kHz interval between broadcasting frequencies of AM stations and 100 kHz or 50 kHz for FM stations. The illustration shows the 50/9 kHz zones (regions 1 and 3), and the 100/10 kHz zone (region 2).
This product is not equipped with a span selector. However, it will be adjusted to a 9 kHz AM (50 kHz FM) interval when shipped from the factory. Before using the unit, be sure to set it to the AM/FM tuning interval (span) used in your area.
To check the tuning span currently selected:
T o change from a 9 kHz AM (50 kHz FM) interval to a 10 kHz AM (100 kHz FM) interval:
To return to a 9 kHz AM (50 kHz FM) interval:
Caution:
When the unit is left for a few hours after the span has been switched and the AC power lead disconnected, the AM span will be automatically returned to 9 kHz (FM span to 50 kHz). If this happens, set the span again.
When the span is switched, all the memorised stations will be cancelled.
1 Press the ON/STAND-BY button to turn the power on. 2 Press the FUNCTION button until "AM" appears on the display.
If "AM 531 kHz" is displayed, it means that AM stations have been adjusted for a 9 kHz span and FM stations for 50 kHz span. If "AM 530 kHz" is displayed, AM stations have been ad­justed for a 10 kHz span and FM stations for 100 kHz span.
1 Press the ON/STAND-BY button to enter the stand-by mode. 2 Hold down the button and the MEMORY/SET button for at
least 4 seconds. Release the buttons when "AM SP 10 kHz" and "FM SP 100 kHz" are displayed alternately.
The clock display will reappear.
1 Press the ON/STAND-BY button to enter the stand-by mode. 2 Hold down the button and the MEMORY/SET button for at

Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type.
Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type (P.P.): Polypropylene type
