Rechargeable battery
· Do not attempt to open the hearing aid, as it may
damage the battery.
· Never attempt to replace the battery. If battery
replacement is needed, please return your device
to the supplier. The service guarantee is void if
there are signs of tampering.
· The safety of recharging batteries using a USB
connector is determined by the external signal
source. When connected to external equipment
plugged into a wall outlet, this equipment must
comply with IEC-62368 (or IEC-60065, IEC- 60950
until June 20, 2019) or equivalent safety standards.
Dysfunction
· Be aware of the possibility that your hearing aid
may stop working without notice. Keep this in mind
when you depend on warning sounds (e.g. when
you are in traffic). The hearing aids may stop
functioning, for instance if the batteries have
expired or if the tubing is blocked by moisture or
ear wax.
