The device may not look exactly like the guiding illustrations in these instructions. We reserve the right to make any changes we consider necessary.
Correct position of the hearing instruments The left and right hearing instruments can be inserted into either charging slot. The slots are not side specific. Make sure the bottom parts of the hearing instruments are placed well into the charging slots. The ear piece of the hearing instrument should always be placed in the compartment.
Cleaning and Drying Drying and cleaning focuses on tubes, ear pieces and molds. ● Put the hearing instruments into the charging slots and close the lid. UVC cleaning* starts automatically after closing the lid and lasts 15 min ● Ongoing UVC cleaning process is indicated by LEDs (see table “Charging and cleaning status”) ● Drying starts automatically after closing the lid and lasts 4 hours. * Ultraviolet C light, used for hygienic cleansing. Significantly reduces risk for ear infections caused by germs, bacteria and fungi.

Charging tips You may have some questions on how to best charge your hearing instruments. 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 instruments? We recommend charging the hearing instruments 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 instruments.
Page 19
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 instruments for up to 7 hours. Charging times may vary due to the use of the hearing instruments and the age of the power cell. Can I leave the hearing instruments in the charger? Even when fully charged, you can leave the hearing instruments in the charger. They automatically stop ...
Page 20
What happens if I forget to charge? Your hearing instruments will automatically switch-off when the power cell is empty. Charge the hearing instruments as soon as possible. Hearing instruments 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.
Page 21
What should I pay attention to when charging? The hearing instruments 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 ...
Page 22
What if I intend not to use the hearing instruments for several days or longer? ● Short-term storage (up to several days): Turn off your hearing instruments 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 instruments in the charger, the hearing instruments are not turned off. Note that when you turn off the hearing instruments via a remote control or smartphone app, the hearing instruments are not turned off completely. They are in ...
Page 23
● Long-term storage (weeks, months, ...): First, fully charge your hearing instruments. Turn them off via the control element on the housing before storing them. We recommend to use drying products while storing the hearing instruments. At 6 month intervals you will have to charge the hearing instruments 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 instruments' user guide.
Page 24
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 instruments in the charger. Otherwise, the hearing instruments may not be detected by the charger. ● Do not turn off the power strip while the hearing instruments are in charger. Otherwise the hearing instruments will automatically turn on and discharge in the charger. Before you turn off the power strip, remove the hearing instruments from the charger and turn them off via the control element on the housing. ...
