CROS solution
A CROS or BiCROS solution consists of a transmitter and a hearing aid.
The transmitter is placed on the poorer ear. It wirelessly sends sound
from the poorer ear’s surroundings to the hearing aid placed on the
better ear.
CROS (Contralateral Routing of Signals) is a solution for people with
limited or no hearing in one ear combined with normal hearing in the
opposite ear.
BiCROS (Bilateral Contralateral Routing of Signals) is a solution for
people with limited or no hearing in one ear and hearing loss in the
opposite ear.

gives you approximately two hours before the transmitter runs out of
battery.
The beeps are repeated every 30 minutes. Just before the battery runs
out, you hear four descending tones.
Three alternate beeps

Battery performance
The daily battery performance varies depending on your individual use.
If your transmitter runs out of battery, ensure you recharge it by placing
it in the charger. Be aware that restarting the transmitter does not give
you more usage time.
For the best charging conditions, ensure the room temperature is in the
range of +10°C and +35°C (50°F and 95°F).
If your transmitter does not perform for a full day, you may need to
replace the battery. If so, contact your hearing care professional.
