Troubleshooting

No power

  • Try a different wall outlet.

No sound (general)

  • Turn up the Master Volume.
  • Make sure the correct function is selected (Bluetooth or USB).

No sound from the microphone

  • Make sure the microphone is firmly connected to the microphone jack.
  • Make sure the microphone ON/OFF switch is set to ON.
  • Turn up the mic volume.

Bluetooth will not pair or connect

  • Turn off other nearby Bluetooth devices to avoid accidental pairing.
  • Make sure Bluetooth is enabled on your device.

  • Make sure your Bluetooth device supports Bluetooth audio (A2DP).

Missing or broken parts

As the SDL9035 is a legacy model, we no longer manufacture or stock replacement parts for it. We understand this may be disappointing, and we apologize for the inconvenience.

Microphones

The original wireless microphones for this model are no longer in stock. However, a compatible wired microphone is available for purchase and will work perfectly with your machine.

AC Adaptor

If the AC adapter was missing from the box, you can use a compatible adapter that you already own or purchase a new one from an electronics retailer.

Important: If you choose to use a different power adapter, it is crucial that it meets the following technical requirements to avoid damaging your machine:

  • Output: AC 100-240V, 50-60Hz 
  • Plug Type: Standard AC power cord (for a 120V AC, 60Hz outlet) 
  • Current: Not specified 
  • Polarity: Not applicable (AC power) 

When searching, using a phrase like "AC 100-240V 50-60Hz power cord" should give you relevant results.
