The Power transmitters

5.3 Power supply
The Power transmitters are fitted with internal rechargeable Li-Ion batteries which can
power the devices for at least 12 hours.
On the device, the current battery status is indicated by the row of LEDs when it is
green. (Red light represents the recorded noise.) If only one of five LEDs is lit, the
device should be charged. Otherwise, it switches itself off automatically.
In the Start menu of the correlator two battery icons indicate the current battery status of
the Power transmitters, provided both devices are switched on and in reach.
To know the exact battery state of a Power transmitter, read the unit's configuration and
see the Battery level line in the respective menu.
The Power transmitters are charged wirelessly in the transport case.
As soon as the devices are situated at their storage places in the case, they are
recharged inductively, provided the case is connected to mains or to a 12 Volt vehicle
power supply.
Charging takes approximately 12 hours. The row of LEDs indicates the charging
progress. The I/O-LED is flashing during the process. It returns to permanent light
as soon as the battery is full.
NOTE
In order to guarantee the devices' water and dirt resistance, any repairs
must be carried out by SebaKMT or an authorised service partner.
Do not open a Power transmitter yourself. If you have problems with the
battery, please contact your SebaKMT service partner.
5.4 Commissioning
To turn a Power transmitter on, briefly press the I/O pushbutton . The I/O LED is lit.
To turn the device off, press the button until the LED goes out.
The Power transmitter's sensor storage place is fitted with a magnetic switch. As a
result, the transmitter "knows" whether the microphone is currently in use or not.
As long as the microphone rests in the storage place, the Power transmitter remains in
"Stand-by" mode. The internal analog radio module stays off as no measuring data
needs to be transferred. This saves battery power.
As soon as the microphone is taken from the storage place, the Power transmitter
switches from "Stand-by" to "Active" mode. The internal radio module is activated and,
from now on, the recorded data are directly sent to the correlator. The row of LEDs
switches from green to red and represents the recorded noise level.
