Charging tips
You may have some questions on how to best charge
your hearing aids. Read the questions and answers
below. If you have more questions, your Hearing Care
Professional will help you.
"How often do I need to charge the hearing aids?
We recommend charging the hearing aids daily,
even if the power cell is not empty. Charge them
overnight so you can be sure to start your day with
fully-charged hearing aids.
1918
"
How long does charging take?
A full charging cycle takes approximately
3 to 4 hours.
After 30 minutes, it is possible to use your hearing
aids for up to 7 hours.
Charging times may vary due to the use of the
hearing aids and the age of the power cell.
"Can I leave the hearing aids in the charger?
Even when fully charged, you can leave the hearing
aids in the charger. They automatically stop
charging when they are fully charged.
"
What happens if I forget to charge?
Your hearing aids will automatically switch-off
when the power cell is empty. Charge the hearing
aids as soon as possible.
Hearing aids which have not been charged
for over 6 months may be damaged due to an
unrecoverable deep-discharge of the power cell.
Deep-discharged power cells cannot be charged
anymore and have to be replaced.
2120
"
What should I pay attention to when charging?
The hearing aids and charger must be clean and
dry. Observe the operation conditions in section
“Operating, transport, and storage conditions”.
Avoid charging at high ambient temperatures, as
this can shorten the life span and capacity of the
power cell.
If you use the charger in a very warm environment,
note that it will stop charging in order to cool down
if the charger’s temperature exceeds 45 °C. The
LED light will blink 3 times in 2 seconds when this
happens. Charging resumes automatically after the
device has cooled down. Do not touch the hearing
aids, they may be hot.
"
What if I intend not to use the hearing aids for
several days or longer?
■Short-term storage (up to several days): Turn off
your hearing aids via the control element on the
housing or place them in the powered charger.
The charger must be connected to the power
supply. If the charger is not connected to power
supply and you place your hearing aids in the
charger, the hearing aids are not turned off.
Note that when you turn off the hearing aids via a
remote control or smartphone app, the hearing
aids are not turned off completely. They are in
standby-mode and still draw some power.
2322
■Long-term storage (weeks, months, ...): First, fully
charge your hearing aids. Turn them off via the
control element on the housing before storing
them. We recommend to use drying products
while storing the hearing aids.
At 6 month intervals you will have to charge
the hearing aids to avoid an unrecoverable
deep-discharge of the power cell.
Deep-discharged power cells cannot be charged
anymore and they have to be replaced. We
recommend recharging more frequently than
6 months intervals.
Observe the storage conditions in hearing aids’
user guide.
"
What should I pay attention to when using a
power strip with energy-saving features?
■Turn on the power strip before you insert the
hearing aids in the charger. Otherwise, the hearing
aids may not be detected by the charger.
■Do not turn off the power strip while the hearing
aids are in charger. Otherwise the hearing aids will
automatically turn on and discharge in the charger.
Before you turn off the power strip, remove the
hearing aids from the charger and turn them off via
the control element on the housing.
2524
"
What happens if I open the lid during the cleaning
process?
The cleaning process will be paused. After closing
the lid again, the process will resume.
But if you remove the hearing aids from the
charger before end of the cleaning process, the
timer will reset.
A new 15 min. cleaning cycle will start after
reinserting the hearing aids and closing the lid.
