both MW and LW.

Band selectors (band)

FM:

Press this button to listen to an FM broadcast.

MW:

Press this button to listen to an MW broadcast.

allocatlon:

This butlon is also used to select a Írequency

step oÍ either 9 kHz or 10 kHz.

When the MW button is pressed tor about 4

seconds, the MW Írequency step will change to

10 kHz peí step.

ohis step is set to 9 kHz beÍore shipment.)

Set to the appropriate position Íot your locality.

ln order lo return to the original írequency indica-

tion, press this button Íor about 4 seconds a9ain.

LW:

Press.this button to listen to an LW broadcast.

íreq shlít:

When the LW butlon is pressed íor about 4

seconds during reception oÍ an LW broadcast,

the LW írequency will decrease by 2 kHz.

So, íor example, to receive 153 kHz' tune lo 'l55

kHz, and then press this button.

tion, press lhis button Íor aboul 4 seconds again.

Digital írequency display

The reception Írequency oÍ the FM or AM broadcast

selected by using the tuning buttons or the pÍeset-tun-

ing butlons is indicated by a digital-type display.

(quartz lock)

This indicator illuminates when tuned

precisely to an FM or AM station.

Memory indicator (El)

This indicator illuminates when the

memory butlon is pressed.

Channel display

The channel number se]ected by the pÍeset'

tuning buttons is displayed.

Signal-strength indicators (signal )

These indicators show the relative strength oÍ broadcast

signals being received by the antenna. The best condi-

tion Íor reception, íor FM and AM' is when the indicators

illuminate completely to the right.

Tuning buttons (tuning)

These buttons are used Íor tuning

to the desired broadcast station.

Memory button (memory)

This button is used when preset memory setting

oí the preset-tuning buttons is made.

FM mode selector (FM mode)

This unit automatically switches into the stereo mode

when a steíeo broadcasl is received. Press this button

lo listen in the monaural mode. The slereo indicator will

not illuminate in the monaural mode.
