The lFS<50 is a cordless speaker system with a built-in
amplifier which employs infrared rays. You can enjoy music

equipment through either a line output jack or a
headphones jack.

This cordless speaker system can be moved easily and be
set almost anywhere, truly adding your listening pleasure.

is generally not susceptible to problems such as external
noise. produces an excellent sound quality.

- Power saving feature - power is turned on automatically
only when audio signals modulated to infrared rays are
received -prevents unnecessary battery discharge,

0 The battery cassette makes battery replacement easy

screen placed near the speaker system.

interrupted and hissing may be heard,

from the transmitter, a hissing noise may increase, and it

This is a characteristic of infrared rays and does not
mean that the unit is defective.
