Switch on the OPUS 2 speech processor and make sure that it is supplied with batteries. Place
the coil underneath the Speech Processor Test Device (see Fig. 19). The coil will position itself
correctly due to magnetic attraction.
When speaking into the microphone, the red light on the Speech Processor Test Device should
flicker in the rhythm of your voice. If the red light does not light or is on constantly, try the
following steps:
• Adjust the volume setting. By using the appropriate loudness setting, you should be able to
recognize the flickering of the LED in the rhythm of your voice.
• Change the batteries.
• Replace the existing cable with a substitute cable.
We recommend you try these steps independent of the use of your Speech Processor Test
Device. If these measures are not successful, immediately contact your CI center or MED-EL.
Do not try to open the speech processor or to disassemble the coil as this will cause damage
to the device and immediately voids any warranty.
The Speech Processor Test Device should be handled with care to achieve maximum lifetime
and ensure proper function. Do not expose your Speech Processor Test Device to conditions
other than those suitable for your OPUS 2 speech processor (see also Chapter 7, General
precautions and warnings).
The FineTuner transmits commands to the OPUS 2 speech processor via a radio frequency (RF)
link. If the , the below describes potential
reasons for this occurring and provides information to assist you in solving the problem:
• The OPUS 2 is out of the FineTuner’s operating distance. To overcome this you should
move the FineTuner closer to the OPUS 2.
• The FineTuner keyboard lock is active. In this case follow the instructions for the unlocking
function as described in Chapter 5, OPUS 2 speech processor, FineTuner, FineTuner functions.
• Interference from other electronic or electrical equipment is present that blocks the
transmission. To eliminate this interference you need to move the FineTuner closer to the
OPUS 2 and/or go to a different location.
• The OPUS 2 and the FineTuner are not synchronized. In this case you need to refer to the
section described in Chapter 5, OPUS 2 speech processor, FineTuner, How to configure your
FineTuner.
• In the case of a suspected malfunction of the FineTuner you need to remove the battery and
re-insert it after a few minutes as described in Chapter 8, Care and maintenance, Batteries,
Changing the battery of your FineTuner.
