FAQs

Q. Where should the microphone be positioned?
A. Select a suitable location to place the microphone in the gondola. It is not possible to specify an exact location, as there are different types of wind turbines. In the WTG nacelle, the corresponding cut-outs or mounting holes should preferably be made at the bottom of the cladding. The noise from wind and turbine blades should also be included in the placement considerations. To increase the life of the microphone, it should always be positioned with the opening downwards to a maximum horizontal position to prevent moisture accumulation inside. Also, pay attention to the surroundings of the microphone. Close objects or surfaces can reflect sound and distort the recorded bat cries.

Q. How do I attach a microphone?
A. Create the holes required for installation: drill the main hole with a hole saw (Ø min.50mm max.56mm) and drill fixing holes, diameter depending on the screws to be used. Fasten the microphone sensor holder in the main hole and secure it. Route and secure the microphone sensor cable so that it is not parallel to the power lines of the generator.

Q. Where does the microphone get referenced in the audio file?
A. After recording, a file is saved in a standardized audio file. Example 0001_2e170926_Test0001.wav:
"0001_" is the serial number of the device. "2" is channel / Mic 2. If an "m" appears it is a manual recording. The letter after is either an "e" or "m" for evening or morning. "170926" is the recording time. "Test0001" is the project ID.

Q. What should I do if there is a lot of noise in the recording?
A. Change environment and/or microphone orientation.

Q. What if no triggers are recorded?
A. This could be one of two things - 1. Microphone is defective - test and/or replace the microphone. Or, 2. The trigger settings are wrong and need to be checked and adjusted.

Q. What does a continuous yellow status light mean?

A. This is either that no recording time is defined and the BATLOGGER wont record. Or, a microphone or sensor has failed during operation. The BlConnect service and the web interface show which channel is affected. Please check the microphone and sensor connections. The error is reset by a reboot.
