Flight mode
When boarding a flight or entering an area where RF transmitters are prohibited, wireless functionality must
be deactivated, as it is not allowed to radiate radio signals during flights or in otherwise restricted areas.
Follow the following steps to enter and leave flight mode:
It is possible to disable wireless operation by opening and closing the battery compartment three times
within a ten second period (open-close, open-close, open-close). Your instruments will now be in flight
mode.
If the hearing instrument is in flight mode, the hearing instrument must have been operating in flight mode
for at least 10 seconds before attempting to enable wireless again. it is possible to re-enable wireless opera-
tion by opening and closing the battery door once. 10 seconds after this operation is completed, wireless
operation will begin again.

Note: It is important to wait an additional 15 seconds after wireless function resumes before open-
ing and closing the battery compartment again for any reason. If the battery compartment is opened and
closed during this 15 second window, flight mode will resume.
Telephone use
If your hearing instruments are fit with a receiver open dome or receiver tulip dome, you can probably
use the telephone as you normally would by holding it up to your ear canal opening. If your hearing
instruments are fit with a receiver power dome or RIE mold, finding the optimal position for holding a
telephone while using a hearing instrument may require practice for some individuals, and one or more
of the following suggestions may be helpful.
1. Hold the telephone as you would normally.
2. Hold the telephone towards the top of the ear (closer to where the
microphones are located).
3. If whistling occurs, it may take a brief moment of holding the telephone in
the same position before the hearing instrument adapts and reduces the
feedback.
4. Any whistling may also be decreased by holding the telephone slightly
away from the ear.
5. Depending on your individual needs, your hearing healthcare professional
may activate a program specifically for telephone use.
