Ultrasonic Microphone to capture bat recordings. Connect one (1) ■ or two (2) ultrasonic microphones. NOTE: With an optional acoustic microphone, the SM3BAT recorder is also capable of recording non-ultrasonic wildlife such as birds or frogs. How to Connect Optional Microphones You can connect one or two external microphones. - Page 18 SM3BAT Setup SM3BAT User Guide NOTE: Mounting cabled microphones on ungrounded non-conductive masts especially in dry and windy conditions, could result in damage to the microphones or recorder due to electrostatic build up or lightning. Such damage is not covered under warranty so please check with a professional/licensed electrician or installer of outdoor antennas, weather instruments or the like for advice suitable to your specific situation.

The internal battery is only a backup to preserve the time settings if there is no main power or the SM3BAT is turned OFF. The unit will still operate properly with a dead clock battery; however, the clock will need to be reset if the D cells are removed or depleted. - Page 31 Order an SM3BAT with this option or place a new order for the GPS time- synch receiver for the SM3BAT.
- Page 32 Details of Operation 3.18.1 The SM3BAT wakes up 150 seconds before a scheduled recording to give the GPS time to acquire satellites. (Without the GPS option, the SM3BAT wakes up 30 seconds before a scheduled recording.) The recording starts within a fraction of a millisecond of GPS time.
- Page 33 You can also view the GPS locations per recording period and clock drift in the Summary file, generated by the SM3BAT while recording. The drift is logged as time delta from the SM3BAT real-time clock (RTC). Negative numbers means the RTC is slow relative to GPS while positive numbers mean the RTC is fast relative to GPS.

Page 34: Programs
This section describes how to work with programs on the recorder using the LCD screen main menu and keypad. The operating behavior of the SM3BAT is controlled by a program file. You can create and save multiple programs; however, you can only load one active program at a time on the recorder. -
Page 35: How To Load A Built-In Program
Once loaded, the program will remain on the SM3BAT even without power. You also have the flexibility to edit one or more lines in the built-in programs to satisfy your specific objectives. -

Page 38: How To Start A Program
If the scheduled start time is more than one minute into the future (three minutes if using the GPS option), the recorder enters sleep mode to conserve power. The SM3BAT wakes up 30 seconds before the scheduled recording start time. The device automatically wakes 2 minutes early when the GPS time- synch receiver option is detected and wakes 3 minutes early when hydrophones are installed. -
Page 39: How To Stop A Program
SM3BAT User Guide Programs For example, if you have a program that starts with AT TIME 16:00:00 and you are in the field starting the program at 17:00:00, the SM3 will go back 24 hours and move forward to the current time and realize the intention is, not to wait until 16:00:00 the following day, but to begin recording immediately. -

Page 46: Program Commands
Developing Custom Programs SM3BAT User Guide Program Commands Use the following commands to create programs for your specific recording needs. A program can contain up to 99 command lines. NOTE: Some commands listed in this section refer to sunrise or sunset in a general sense and depend on them in program calculations. - Page 47 SM3BAT User Guide Developing Custom Programs FS <WAV,WAC> {OFF,0,1,0+1} <sample rate> Specifies the file type produced, the source channels used, and the sample rate for full-spectrum recordings. Channel and sample rate both have AUTO selections available. Choose the standard .wav format for recording bats. It consumes less power and can be opened in any audio software.
- Page 48 Specifies the source channels used and the division ratio for zero-crossing recordings. AUTO settings are available. Zero Crossing is not the same as full-spectrum recording. In full spectrum recording, the SM3BAT samples audio signals at a specified sample rate. In page BIOACOUSTIC MONITORING SYSTEMS...
- Page 49 During the scheduled recording period, SM3BAT will create zero crossing sequence files for each trigger. The SM3BAT assesses each sequence to verify that it is a bat pass and not a non-bat trigger. The resultant files can be opened directly and analyzed with Wildlife Acoustics’ Kaleidoscope software or third party zero-crossing software.
- Page 50 Developing Custom Programs SM3BAT User Guide This command is only relevant if TRGLVL is not OFF. See DMIN for more information on how the scrubber uses this value. See TRGLVL for more information on how the trigger uses this value.
- Page 51 NOTE: Triggers do not work well for most acoustic applications, but this command must be used to prevent an error. Off or Auto should be selected (Auto will select Off as well). This is to maintain cross compatibility of programs from SM3 to SM3BAT. TRGWIN <window-channel-0> <window-channel-1>...
- Page 52 Pauses the program for the specified amount of time. If you set the duration of the PAUSE command to greater than 1 minute (3 minutes if using the GPS option), the SM3BAT enters low-power sleep mode and wakes up at the next scheduled recording.

Page 58: Managing Deployments
However, the batteries will discharge on their own over time. When recording, depending on accessories, sample rates, compression, and other variables, the SM3BAT can use as little as 500 mW power. That translates to up to 2 weeks of nightly recording using high-quality alkaline batteries. Use the SM3 Configurator to estimate a recording schedule based on your program requirements. - Page 59 SM3BAT User Guide Managing Deployments In most applications, there is no reason to use sampling rates faster than twice the frequencies of interest. The majority of frog vocalizations are under 4 kHz and need only be sampled at 8 kHz while most bird vocalizations are under 8 kHz and need only be sampled at 16 kHz (with the exception of some high-pitched warblers who sing at 12 kHz and need to be sampled at 24 kHz).

Page 65: How To Measure Microphone Sensitivity
How to Use the Ultrasonic Calibrator 9.3.1 Use the available Ultrasonic Calibrator for the SM3BAT to calibrate SMM/SMM-U1 microphones. Since ultrasound is beyond the range of human hearing, verifying proper system and microphone performance can be a challenge. The Ultrasonic Calibrator helps you test both the microphone and the full recorder system. - Page 66 Install the clear calibrator microphone adapter by sliding it onto the calibrator from the bottom (the end with the Wildlife Acoustics logo) until it is touching the toggle switches. Place the microphone in the calibrator microphone adapter. Make sure that the side with the smaller hole diameter is near the toggle switches.
- Page 67 Chirp Mode 9.3.3 To test the SM3BAT system, the Ultrasonic Calibrator can emit loud ultrasonic signals to the recorder while it is recording from some distance. Analyze these recordings to verify that the recorder settings are appropriate and the system is functioning as expected.
