Practical help
Common problems
Speaker damage
Ensure correct polarity is observed when connecting the loudspeaker to the amplifier output. Reverse polarity can damage the unit.
Hearing impairment
Do not operate the device continuously at high volume. Turn down the volume immediately if background noise or hearing failure occurs.
Before use
- Ensure the speaker is installed in a suitable housing before operation.
- Verify that the amplifier output is compatible with the 8 Ohm impedance of the speaker.
- Check that the installation environment is free from extreme temperatures, humidity, and excessive dust.
- Confirm that all packaging materials have been removed and disposed of properly.
