The loggers are shipped from the factory to the user in a "deep-sleep" mode (also called
shipping mode) to conserve battery life. They need to be activated before use (i.e. They
do not operate until the user has reset them by swiping them). Once activated, they
operate normally. They should be put back into "sleep mode" if stored unused for a long
period in order to maximise the battery life of the unit.
The logger device can be reset by swiping a magnet over the side of the plastic case (the
base of another logger is a good way to do this). This will activate a magnetic switch
inside the logger which causes it to reset and consequently to "wake up" from shipping
mode. This is the only way to reset the unit.
A successful reset / start operation is
confirmed by observing the two LEDs
(positioned next to the antenna connector)
alternately flash after swiping.
Reset of the logger does not erase
any measurement history.
Reset of the logger does temporarily re-activate the radio-link (for approx. 2 minutes).
(The radio link may otherwise be in standby, depending on the logger settings).
Loggers used for sound correlation purposes should not be reset until the sound file
has been produced and downloaded. Caution is therefore needed. Keep loggers
separated to ensure they are not accidentally reset during handling when using them
for correlation.

The loggers have two LEDs positioned below a thinned-out area of the top of the plastic
body.
The LED activity times are set within the factory and cannot be changed. They can be
active constantly, only active during patrol times, or only after a logger reset.
