Getting to know your charger

Seen from behind

Getting started

Placing your hearing aids in the charger
Fully charge your hearing aids before using them.

1. Plug the power adaptor into a power outlet and connect the charging cable to the hearing aid charger.
2. Place your hearing aid receivers into the charging bays. The right hearing aid goes into the charging bay with the red color coding. The left hearing aid goes into the charging bay with the blue color coding.

If there are a sports lock attached to your receiver, be careful when placing the receiver into the charging bay.
WARNING:

• Avoid charging your product in extremely high or low temperatures and do not use the charger outdoors or in damp areas.
• Only recharge the hearing aid charger with the power supply unit that has been supplied together with the product.

CAUTION: Before inserting your hearing aids into the charger, ensure that they are dry.
Charging your hearing aids
While your hearing aids are charging, the on/off light on your hearing aid will blink slowly. When fully charged, the light remains on (not blinking) until your hearing aid is removed from the charger.

When you insert your hearing aids into or remove them from the charger, the five lights on the front of the charger show the charge level of the hearing aid with the LOWEST charge. They light for 10 seconds and then turn off. If your hearing aids are in the charger, they will continue to charge.

Charging the charger

Plug the power adapter into a power outlet and connect the charging cable to the hearing aid charger.
The three lights at the back of the charger show the charge level of the charger. One red blinking light indicates that the battery is low and needs to be recharged. Three green lights mean it is fully charged.
When the charger is fully charged, it can fully charge your hearing aid three times before the charger itself needs to be plugged in and recharged. Number of lights| Battery level
---|---
•| Light blinking red – less than 10% remaining
•| 10-33% charged
• •| 33-66% charged
• • •| 66-100% charged

NOTE:

• When charging your hearing aid charger for the first time, let it charge for at least 3 hours, even if the battery lights indicate that the battery is fully charged.
• It is safe to leave the charger connected overnight – the batteries in both the hearing aid charger and the hearing aids cannot be overcharged.

Battery FAQ

How do I prepare a new battery?****

– Normally no preparation is required. If necessary, charge the hearing aids in the charger and watches the battery lights on the charger. You can also see the battery level on the smartphone app.

Can I damage a battery by using it incorrectly?****

– No. The only exceptions would be the use of excessive physical force or extreme temperatures.

Must I remove the hearing aids from the charger once they are fully charged?****

– No. For example, you can leave your hearing aids in the charger overnight.

Must I use up all the battery power before charging again?****

– No. Regular charging such as charging overnight is considered normal use. The batteries in the hearing aids and charger can be recharged at any level of charge.

Must I charge the hearing aids fully before use?****

– Only the first time. A partial charge is fine and will not harm the hearing aids or the battery, but a full charge will provide the longest usage without needing to recharge.

Is it OK to interrupt the charging of the hearing aids or charger before fully charging?****

– Yes. A partial charge causes no harm.

Why don’t my hearing aids turn on automatically after being in the charger for an extended period of time?****

– If you leave your hearing aids in the charger for more than 24 hours without having the charger connected to power, the charger will go into standby mode and turn off the hearing aids. If the charger is not connected to power and the charger battery runs out of power during charging, it will turn off the hearing aids to save hearing aid power. When you remove your hearing aids from the charger, they will not turn on automatically as they usually do. Press the push button for 5 seconds to turn on your hearing aids manually.

Does the battery heat up when charging?****

– There is a slight temperature increase at the end of the charging process.

Can I charge the charger or hearing aids at low temperatures?****

– If the temperature is below +5°C (+41 °F), it will not charge. Charging must take place between +5°C (+41 °F) and +40° C (+104° F).

Can I charge the charger or hearing aids at high temperatures?****

– The operating temperature range for the charger and the hearing aids is +5°C (+41 °F) – +40° C (+104° F).
