Loggersynchronizationisinitiated/terminatedbyselectingtheappropriatemenuitemorfunctionbuttonin
the main window or by simply pressing F2. Logger synchronization allows programming of the loggers by

Explanationofoptions:
Synchronize only reachable loggers (in case only few loggers are in transmission range, "drive‐by‐
operation"): During synchronization the System Communication Link will search for the next reachable
logger. This op
tion should be used during normal operation when loggers are deployed throughout the
distributionnetwork andonly fewloggersare in transmissionrange. If toomany loggerscan be reachedat
thesametime,theSystemCommunicationsLinkwon'tbeabletoestablishradiotransmissiontoallloggers.

The shorter the time between logger programming and receiving the recorded sound signal the more
accurate the results. As a rule of thumb sound recordings should be transferred to the PC 24 hours after
