DESCRIPTION

TYPE

Radio mute signal output pin.

This pin operates as follows:

• Radio mode

Low level is output at radio ON/OFF, band switching,

and receiving frequency switching.

• Tape and CD modes

High level or Low level can be selected by MUTESEL

switch of the diode matrix to be described later.

However, when using the DK standby or radio moni-

tor function, set the MUTESEL switch to 0 and select

low level output.

For more information, see 4 “Mute Output Timing

Chart”.

Tape and CD mute signal output pin at DK • ON and

radio monitor ON.

In the radio mode, Low level is output and in the tape

and CD modes, High level is output. When DK is turned

on during DK standby and in the radio monitor mode,

low level is output.
