Operating instructions
This charging base is intended to charge your
rechargeable hearing aids. Use only with Silver
Zinc (AgZn) rechargeable batteries. This product
does not have a power switch. It is turned on
once you plug in the power cord.
To get started, plug the power cord into the USB
wall adapter and into a power outlet. When it’s
rst plugged in, both charger lights will briefly
turn green.
Charging Your Hearing Aid
1. Lightly hold your hearing
aids by the tube, and
place them in the charging
slot. Both domes should
be facing the same side
of the charger as the
power cable, as shown
in the picture. When your
hearing aids are correctly
placed, both lights will begin blinking green.
2. Once the green
lights have blinked
approximately 5 times,
your hearing aids are
charging. When the lights
stop blinking and turn
solid green, your hearing
aids are completely charged. This will take
approximately 5-7 hours.
3. You can remove your hearing aids before
they’re completely charged, but they won’t
last as long as when they’re fully charged.
It’s best to leave your hearing aids in the
charger anytime you’re not using them, they
won’t overcharge.

Caring for your charging base
Charging Tips
• Charge the hearing aids daily, preferably
overnight, before wearing them.
• Charge the hearing aids at temperatures
between 50°F (10°C) and 104°F (40°C).
• If you don’t intend to use your hearing aids
for several days, it is best to either:
• Remove the batteries, or
• Leave the hearing aids in the charger while
it is plugged into a power supply. The
hearing instrument will not overcharge.
• Don’t place the hearing aids in the charger if
the charger is unplugged, this will drain the
batteries.
• If you receive a low battery warning from
the hearing aids, place hearing aids in the
charging base for charging or replace with
non rechargeable batteries.
• Each battery should last for approximately
one year, and can be easily replaced by your
hearing healthcare professional at that time.
Cleaning
• Use a dry, so tissue to remove any debris.
• The so brush that is included with hearing
aids may be used to clean the contacts on
the charger.
• Do not sterilize or disinfect the charger.
• Do not clean with rubbing alcohol, solvents
or any other liquid.
