Anabat bat detection system: description and maintenance manual.

Abstract

Anabat bat detection systems record ultrasonic bat calls on cassette tape by using a sophisticated ultrasonic microphone and cassette tape interface. This paper describes equipment setup and some maintenance issues. The layout and function of display panels are presented with special emphasis on how to use this information to troubleshoot equipment problems. The maintenance section describes opening the equipment, identifying an internal battery, removing panels for maintenance, reinstalling a dislodged light sensor, replacing a broken switch, constructing and replacing a critical battery stack, and making an external power cable. A short discussion on the Anabat software describes how to access, install, and check the Anabat5 program for use with the Anabat equipment. The unit used to access field data collected on a cassette recorder, the zero crossings analysis interface module (ZCAIM), is briefly addressed with a section on how to adjust the tape recorder head skew so that field data can be reproduced accurately on a laboratory recorder. Tips for handling 12-volt rechargeable batteries also are included.
