CROS hearing aids
CROS (Contralateral Routing of Signal) hearing aids are fitted
to patients who can only hear properly in one ear. The CROS hearing
aids work by sending all the sounds from the "no hearing" ear to
the "good" ear. To see which model you have, please check either
your battery card, individual care plan or your hearing aids.
Operating your hearing aids
Turning your hearing aids on/off
To turn the hearing aid on, close the battery door. To turn the
hearing aid off, open the battery door.
Left & right hearing aid markings
There is a red or blue marking on the back of the hearing aid.
Red marking is for the right hearing aid and blue marking is for
the left hearing aid.
Volume control, CROS balance control and programs
Depending on how your audiologist has set up your hearing aids,
you may have a volume control and/or programs added.
Controls for the hearing aid that is on the 'good'
ear: You should see two buttons on your hearing aid which
controls the volume. A quick press of the top
button turns the volume up. A quick press of the bottom button
(button closest to the battery door) turns the volume down.
Controls for the CROS device on the 'no hearing'
ear: You should see two buttons on your CROS device
which controls the CROS balance (i.e. signal
balance). A quick press of the top button increases hearing more
from the side where there is no hearing. A quick press of the
bottom button (button closest to the battery door) decreases the
amount you hear from the side where there is no hearing (which
means you hear more from the side of the 'good' ear).
You might have programs on your hearing aids if the audiologist
has added them. To change the program, hold down the button (for at
least 3 seconds or longer) until you hear a beep. One beep is
program 1, two beeps is program 2 and three beeps is program 3. If
programs have been added, your audiologist would have advised you
on what programs are on your hearing aids. Many patients opt to not
have any programs and only have a volume control, as the hearing
aids can automatically adjust its settings to optimise the sound
quality in its environments. If you would like a
telecoil loop program added, please contact the Audiology
department.
If you opted to keep things simple at your fitting appointment,
your hearing aid may have been set to fully automatic mode, which
does not require you to press any buttons.
Changing the battery
To change the battery, lift the old battery out of the battery
door. Then remove the sticker off the new battery and place the new
battery into the battery door vertically with the flat part (i.e.
"+" symbol) facing up.

MyPhonak app video
Please note that you will not be able to see your battery levels
in the app on these hearing aids as they are non-rechargeable. Also
you must have internet connection the first time your hearing aids
are paired to the app. If you have an audiology appointment and the
clinician changes the settings on your hearing aids, your custom
programs may be deleted on the app.
If you have lost pairings or having problems with App:
• Delete the app
• Go into the Bluetooth settings menu and delete all pairings to
the hearing aids
• Restart the phone
• Open the Bluetooth settings menu and pair to the hearing aids
(this will just pair to one of the aids) but it establishes the
connection we need for call streaming
• Then reinstall the app
• Restart both hearing aids and pair both in the app
