CIRCUIT DESCRIPTION

1. New Functions

1-1 Amp section

(a) LCD Remote Control with System Control Code

Display on remote control shows the present condition
of others units;CD player, cassette deck and so.

(b) One Touch Operation

• In power off mode, system will turn on and start to play­back if play key on every unit; CD, DECK, DVD, and MD
will be pressed .

• In power off mode, system will turn on and start to open
if open/close key on every unit; CD, DECK (single),
DVD, and MD will be pressed

(c) Voice Activation (C-V150/V350)

In voice activation mode, when system has "KEN­WOOD" word it will turn on and start to playback CD or
LD player even if power switch is turn off.
Key word will be available of changing any other word.

(d) Automatic Power-off

The system will be turned off if it is turned on by voice
activation and selector keeps position at CD or LD posi­tion and system does to stop condition for 30 mints in
CD or LD mode.

1-2 Tuner section

EON(Enhanced Other Network) (C-V150/V350)

• Automatic memory (broadcasting station name with sort
mode), FM station will be morized after RDS station are
done.

• In the case of broadcasting TA(Traffic information),
NEWS(PTY), and INFO(PTY) in same network station,
system will receive TA, NEWS, INFO or normal broard­castings automatically.
