A-9150 - Troubleshooting: Remote Controller

The remote controller doesn’t work properly.

• Make sure the batteries have been installed with the correct
  polarity (+/–).
• Replace both batteries with new ones. (Do not mix different
  types of batteries or new and old batteries.)
• The remote controller is too far away from the integrated
  amplifier, or there’s an obstacle between them.
• The integrated amplifier’s remote control sensor is being
  subjected to bright light (inverter-type fluorescent light or
  sunlight).
• The integrated amplifier is located behind the glass doors
  of an audio rack or cabinet.
