Introduction
A Contralateral Routing of Signals (CROS) hearing system is a
type of hearing aid that is used to treat unilateral hearing loss.
It takes sound from the ear with poorer hearing and transmits
it to the ear with better hearing. CROS only picks up sound
from the unaidable ear, while BiCROS picks up sound from
both ears. This helps the patient to receive sounds from both
sides of the head without the head-shadow effect.
Multifunction Button Balance Control
Your hearing system uses the button to adjust the balance
between the hearing aid and the transmitter. This control
adjusts the level of sound coming from the transmitter. Press
and release the button until the desired level is reached. Each
press and release changes the balance level one increment.
NOTE:
Balance Control is only applicable for BiCROS
memories.
CROS Streaming
Your hearing system is equipped with a CROS transmitter.
When you enter a memory with either CROS or BiCROS
streaming enabled, audio from the transmitter is streamed
to your hearing aid. When CROS streaming begins you
may hear an alert tone. If for any reason the CROS stream
is unexpectedly interrupted you may also hear an alert tone.
Please ask your hearing professional about your particular
settings.
CROS/BiCROS Technology
Operation
General Telephone Use
Some hearing aids work best by holding
the phone close to, but not fully covering
your ear. In some instances, if you
encounter whistling (feedback), tilt the
receiver at an angle until the whistling
stops. Additionally, the hearing aid in
the non-phone ear (ear opposite the
phone) may switch to a telephone
setting to reduce background sounds.
Your hearing professional can provide
instructions and techniques for your
specific needs.
Ear-to-Ear Phone Streaming
The telephone memory in your hearing aid may be equipped
with an ear-to-ear phone streaming option. When you enter
your telephone memory, the audio from your telephone will
be streamed from the phone ear’s hearing aid to the opposite
ear’s hearing aid. This allows you to hear the telephone
conversation in both ears. Ask your hearing professional about
your particular telephone settings.
