Easy telephone
Your hearing aids may also have a telephone
feature, which automatically switches to a
dedicated telephone program when a receiver
is brought close to one of your hearing aids. You
will hear a short melody when you switch to
the easy telephone program. When the receiver
is moved away from the hearing aid it will
automatically return to the previous listening
program.
Wireless synchronization
(jazz ST 312 Dir W only)
When you change the volume or program
settings on one hearing aid, the other one
changes as well. Wireless synchronization
works for both the push button and the rotary
dial.
For example, if your push button is configured
as a program control, when you push the
button on one hearing aid, the program will
change on both hearing aids.
