Here you connect the supplied DC adapter for powering EarIn.
Alternatively you can insert a 9V battery in EarIn to operate the unit
without the DC adapter. When the DC adapter is connected with a
battery inserted, the battery is automatically disabled.
NOTE: Use only the supplied DC adapter, otherwise the unit can be
damaged. In addition, please note that EarIn can not be used to char-
ge an inserted 9V accumulator!
