lCF-IR7

The lCF-IR7 is a remote-control clock stereo system. which
employs an omnidirectional remote control device using
infrared rays. Since the speakers are not connected to the
remote commander by a connecting cord, you are free to
customize the system installation in many different ways.

- The 2-way ¢speaker system enables you to enjoy stereo
sound with powerful bass.

- The remote commander is compact and thus highly
versatile.

- You can choose from three alarm sounds: a radio alarm,
a buzzer alarm, or a dual alarm that combines both Alarm
A (radio) and Alarm B (buzzer).
alarm: Alarm A (radio) and Alarm B (buzzer).

o The system has a memory for to preset stations. We
recommend you to preset your favorite stations for easier
tuning.

- The Sony Discman with REMOTE jack may be connected
to the speaker and controlled by the remote commander.
