MTL
METAL signal METAL signal output pin
output
The output level depends on the METAL state, as listed below:
METAL state
ON
OFF
Output level
High
Low
If the TPSET switch is set to on, the output level depends on the
METAL state, regardless of the current mode.

CDOUT CD mode output CD mode output pin
Each time the CD momentary key is pressed, the CDOUT output
is inverted. In the following modes, the CDOUT output is always
set low:
When IGNITION is low
In power-off mode (when IGNITION is high and the radio, tape,
and CD are off)
When the DTH transistor switch is set to off
