  1. Remove the 20P connector (A) from the cable reel (B).
  1. Measure resistance between the No. 9 and No. 10 terminals in each switch position according to the table.
Position
Resistance
OFF
About 10 kΩ
MODE
About 6.0 kΩ
CH (+)
About 2.0 kΩ
CH (−)
About 840 Ω
▲
(VOL.UP)
About 370 Ω
▼
(VOL.DOWN)
About 100 Ω

  1. In the resistance is not as specified, replace the audio remote switch.
  1. Use a diode tester between the terminals in each switch position according to the table.
  1. If the diode test is bad, replace the switch.
