Troubleshooting guide

To use the monitor earphones:
•
Ensure the sound processor is on.
•
Plug the monitor earphones into the base of the BTE controller.
— Caution: Do not use force.
•
Monitor earphones will turn off after 90 seconds.
•
Push both the ‘Increase’ and ‘Decrease’ buttons at the same time for a
few seconds to activate.
•
Should you wish to test an accessory, plug it in to the monitor
earphone connector.
•
Listen to sounds.
•
While listening, press any button
on the BTE controller, for more
than one second, to re-activate
the earphones, or if they turn off,
press increase/decrease again.
•
Should you wish to test an accessory,
plug it in to the monitor earphone connector.
•
Listen to sounds.
Monitor earphones only indicate that sound can be heard. They do not
indicate the quality of sound as heard by the sound processor user.
Electromagnetic interference
Move away from any electronic device that may be causing interference, e.g.
buzzing sounds or distorted speech.
Most electronic devices produce electromagnetic fields. Headset cables, like
antennae, pick them up. Common sources of interference include:
•
Radio and TV transmission towers
•
Mobile phone towers
•
Shopping center and airport security systems
•
Some digital mobile phones
•
Battery chargers
The electronic interference (EMI) will be no louder than the programmed
levels and will neither hurt nor damage the processor. If buzzing is still heard,
or distorted speech, turn off the speech processor, take off the coil and
consult the implant clinician.
