Speaker doesn’t work at all, no sound from the
speaker:
Check that the power connector on your power supply is
suitable for the power socket on the speaker (2.1mm, centre
positive).
Check that you have switched your radio communication equip-
ment on and that you have a signal for the speaker to process.
To verify this, remove the audio connector from the external
speaker socket on your equipment.
Check that the LED on the front of the speaker is illuminated
green, when the noise cancellation is on (NES10-2 only).
The speaker works but the noise cancellation doesn’t
appear to improve the audio quality of the signal:
Check that the LED on the front of the NES10-2 changes from
red to green when the noise cancellation is switched off and
on (NES10-2 only).
Now switch the noise cancellation on, you should clearly hear
the difference now.
