Setting the AC voltage selector

Connecting the AC power lead

Check the setting of the AC voltage selector located on the rear panel before plugging the unit into a wall socket. If necessary, adjust the selector to correspond to the AC power voltage used in your area.

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.

Turn the selector with a screwdriver until the appropriate volt- age number appears in the window (110 V, 127 V, 220 V or 230 V - 240 V AC).

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 elec- tric 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 ).

System Connections (continued)

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:

1Press the ON/STAND-BY button to turn the power on.

2Press 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 ad- justed for a 10 kHz span and FM stations for 100 kHz span.

To change from a 9 kHz AM (50 kHz FM) interval to a 10 kHz AM

(100 kHz FM) interval:

1Press the ON/STAND-BY button to enter the stand-by mode.

2Hold 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.

To return to a 9 kHz AM (50 kHz FM) interval:

1Press the ON/STAND-BY button to enter the stand-by mode.

2Hold down the button and the MEMORY/SET button for at least 4 seconds. Release the buttons when "AM SP 9 kHz" and

"FM SP 50 kHz" are displayed alternately. The clock display will reappear.

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.
