When the MUTE key is pressed and the MUTE output goes high, a –79 dB data item is sent to the electronic volume control IC.
–20 dB
1
When the MUTE key is pressed and the MUTE output goes high, a data item for only –20 dB less than the current volume is
sent to the electronic volume control IC.
0
When the LC7233N-8818 enters the ACC OFF state (when HOLD is low) a panel removal reminder alarm is not output from the
ALARM pin.
When the LC7233N-8818 enters the ACC OFF state (HOLD is low) a panel removal reminder alarm will be output from the
ALARM pin. The alarm signal frequency is about 4.4 kHz, and lasts for about 20 seconds.
ACC OFF

There is no MW2 band, and only the MW band is displayed.
MW2 SEL
1
When there is no LW band, the MW2 band is added, and these bands are referred to as MW1 and MW2. The display for MW1 is
“MW I”, and the display for MW2 is “MW II”.
0
A pulse (high for 250 ms, low for 750 ms) is output from the LEDFLSH pin in the ACC OFF state (HOLD is low) when PANEL IN
is high.
LED FLASH
1
The LEDFLSH pin remains low when the LC7233N-8818 enters the ACC OFF state (when HOLD goes low) and PANEL IN is
high. At this time the LC7233N-8818 enters backup mode if the clock function is disabled.
