OVERVIEW/ FEATURES

The ICFSWEOD is an FM/SW PLL synthesized receiver which features
easy tuning using the frequency-preset cards.

Various ways of tuning using the preset cards

- Easy tuning .......... You can receive a desired station by only
inserting a card in the unit and lightly
touching the station name printed on the
card.

0 Direct tuning ......... Tuning in the station by directly inputting

the frequency of the station.

- Manual tuning ........ Even it you dont know the frequency of the
station. you can tune in the station
precisely.

. .Stations can be preset using the cards.

. .Function for receiving a desired station at a
desired time.

- Preset tuning . . . .
. Timer standby . . .

Other teatures

~ Quartz controlled PLL (Phase Locked Loop) synthesizer system
using a microcomputer for easy pinpoint tuning. The tuned
frequency is digitally dlsplayed.

~ Provided with a recording output jack.

This unit is supplied with tour cards:

three for radio reception (frequency-preset cards and memory
cards), and one for clock/timer setting (Clock Card).

For details on the cards and the receivable preset stations, refer to
