Table
H: Relay ON, L: Relay OFF
Fixed to L in the product whose destination
does not need relay.
Lo: Reset, Hi: Active
q Refer to "Destination setting".
q Refer to "Destination setting".
w Refer to "KEY6"
Output is fi xed to L (Analog input when this
terminal is used)
L when offset is detected
Hi: RELAY_SW1
L: Normal, H: Error (Hi: When SW1 is Low),
Output is fi xed to L in the product whose desti-
nation does not need relay.
Hi: RELAY_SW2
L: Normal, H: Error (Hi: When SW2 is Low),
Output is fi xed to L in the product whose desti-
nation does not need relay.
H: Station exists, L: Station does not exist
Normal: 1.6V, TEL MUTE: 1V or less,
NAVI MUTE: 2.5V or more
L: Active
Not used. Output is fi xed to L
