Getting Started
Before using your Micro Mic, you need to charge the recharge-
able battery. To charge it, plug the charging cable into the Micro
Mic as shown in the picture below.
Next, plug the other end of the charging cable into the charger
and into a power outlet.
During the charging process, the status LED indicator will show
a solid red light. When fully charged and still connected to the
charger, the LED will turn solid red, interrupted by a green blink
every 2 seconds.
Charging an empty battery typically takes about 3 hours. It is safe
to leave the charger connected overnight – the battery cannot be
overcharged.

Note! The following information is primarily intended for your
hearing care professional, who in most cases will complete the
necessary tasks needed before the Micro Mic can be used with
your hearing instruments. However, the process is designed to be
simple and most people can do it themselves.
It is possible to pair up to three ReSound streaming devices - e.g.
one Micro Mic and two TV streamers (optional Unite™ accessory)
- with a given pair of hearing instruments. Therefore, channel 1, 2
or 3 must be selected when starting the pairing process.
