How to preserve and recover the microphone’s function
The microphone is a special ultrasonic sound sensor, made with MEMS technology.
Because of the highly sensitive technology the microphone is sensitive against humidity.
Therefore, by fog, rain or condensed water the sensitivity can decrease massively. Please,
do not blow into the microphone. Particles from cigarette smoke can damage the
microphone permanently.
In most cases the normal function is restored by the next day. Please, keep the device in a
clean and dry place, for example in a dry wooden box. Adding a package of silica gel can
be useful. Please, do not try to dry with excessive warmth, like using an oven, microwave,
hairdryer or heater.
How to exchange the microphone yourself or make use of the service
If the microphone does not regain its normal function after several days, possibly chalk,
salt or dirt particles have accumulated in the microphone. In these cases the problem can
be fixed only by the exchange of the microphone.
With newer SSF-BAT2 devices whose serial numbers end with "S" or are marked with a
green dot (the serial number is in the battery compartment), the microphone is now a
plug-in device and can easily be exchanged by the customer. Spare microphones can be
ordered at www.all-about-bats.net or via email:
