Handling Switch On/Off Switch-On Press adjustments- and On-/Off-button afterwards UP button Einschalten: Taste: , and within 1 sec., otherwise device automatically switches off. This procedure serves to avoid an accidential switch on of the device e. g, in a bag. After switching on device is ready for use. Switch-Off Gerät wird abgeschaltet! For switch-off press adjustments- and On-/Off-button for more than 2 sec. Furthermore if device is switched on and not used within a certain time, device switches off automatically for protection of batteries. Default time is 5 minutes. (See programming „Off“ on page 9).

Graphic on the right Adjustment of mixer frequency Use Up-/Down-button and in normal-mode for adjustment of mixer frequency for Heterodyne-receiver. With every push frequency changes by +/- 1 kHz, while a longer push switches to fast run. Frequency, resulting of mix of ultrasonic frequency and appointed mixer-frequency, will be transmitted via speaker (or headphones). Adjustment of frequency is continuously variable from 15 kHz to 130 kHz. Use of frequency division & heterodyne Parallel to mixer-mode the SSF BAT2 is also scanning the whole spectrum for ultrasonic frequencies using frequency division. The located frequency will be displayed in a graphic. At the same time, strongest located frequency will be displayed on the right (peak-frequency). Through short push of frequency-button this located peak-frequency will be taken as mixer frequency and hearable. 020. 040 045 000 VOL 038 kHz 2 3 4 5 6 7 8 9 0 1 2 038 Use of fixed frequencies Through long push of frequency-button one of the programmed and stored fixed frequencies will be taken as mixer-frequency using the heterodyne-receiver. 020 040. 045 000 VOL 020 kHz 2 3 4 5 6 7 8 9 0 1 2 038 Dot to the right of the fixed frequency shows frequency which will be taken next.

With that function device will not be switched off automatically. In combination with a sound recorder you can easily build a simple eavesdrop box that can be left out overnight. 9 5. Supplement Technical specifications Microphone-frequency range The graph shows the sensitivity of the built-in ultrasound microphone in the range of interest for bat calls. Maximum sensitivity is around 50 kHz. The maximum sensitivity of the elektret-microphones normally used in more simple detectors is from15 to 20 kHz. Frequency response of the pre-amplifier The pre-amplifier is optimised for the amplification of ultrasound signals over 15 kHz. Background noise, that could lead to overmodulation of the sensitive pre-amplifier will be masked out. 10 Block diagram 11 Overview of operation short push long push short push long push mixer frequency +/- 1 kHz Æpage 7 mixer frequency fast run Æpage 7 adoption of scanner frequency Æ page 7 adoption of fixed frequency Æ page 7 Settings Device is switched off: Switch on through push of button Æ page 6 long push device switch off Æ page 6 short push Volume volume +/- 1 next mode volume Æpage 7 ends mode short push frequency +/- 1 kHz Store short choose storage space save fix frequency Æpage 8 long save frequency 4sec. delete frequency short push Light choice 4 level next mode backlight of LCD Æpage 9 mode short push Off choice 9 level next mode end mode 12 time until auto switch off Æpage 9 Development of SSF BAT2 A special thanks goes to all the people who helped with time, input and testing.

Dipl.Ing. Karl Volkmann Ing.büro Volkmann 13 Important information concerning the microphone – Please note! How to preserve and recover the microphone’s function The microphone is a special ultrasonic sound sensor, made with MEMS technology. Because of the highly sensitive technology the microphone is sensitive against humidity. Therefore, by fog, rain or condensed water the sensitivity can decrease massively. Please, do not blow into the microphone. Particles from cigarette smoke can damage the microphone permanently. In most cases the normal function is restored by the next day. Please, keep the device in a clean and dry place, for example in a dry wooden box. Adding a package of silica gel can be useful. Please, do not try to dry with excessive warmth, like using an oven, microwave, hairdryer or heater. How to exchange the microphone yourself or make use of the service If the microphone does not regain its normal function after several days, possibly chalk, salt or dirt particles have accumulated in the microphone. In these cases the problem can be fixed only by the exchange of the microphone. With newer SSF-BAT2 devices whose serial numbers end with "S" or are marked with a green dot (the serial number is in the battery compartment), the microphone is now a plug-in device and can easily be exchanged by the customer. Spare microphones can be ordered at www.all-about-bats.net or via email: firstname.lastname@example.org . You can find the current price on www.all-about-bats.net . Older devices must be sent in for microphone exchange to the company Microelectronic Volkmann In der Gebhardsösch 9 78467 Konstanz www.mekv.de email@example.com In this case there is a service charge of 15.00 plus shipping costs. The service includes a plug-in for easy microphone exchange, firmware-update and an additional hand strap. The quoted prices include the legal German VAT. 14 Instructions for a microphone exchange The work is done at your own risk. Success can not be guaranteed. If you don’t feel confident with this, please send in the detector for repairs. Step by step: You need the following tools: • 1 small Phillips head screwdriver • 1 flat head screwdriver Remove batteries before attempting the repair. Figure 1 Please use the Phillips head screwdriver to remove the 4 screws of the casing (Figure 1). Caution: Be careful with the sensitive electronics when opening the case and working on the microphone. The microphone is to be protected from pressure, dirt and moisture. Do not touch the front of the microphone! Figure 2 Use the flat head screwdriver to cautiously lift the circuit board, as shown in Fig. 2 (The circuit board is held by an adhesive strip). The microphone can now be pulled out to the front. Caution: Do not bend the pins. You need the white plastic disc and the rubber sleeve of the old microphone. These are attached to the new microphone as follows: Begin with the disc. Fit the flat side of the disc from the left onto the microphone, so that there is about 2 mm of space between the left edge and the plastic disc. Now, from the right, slip the rubber sleeve on the microphone. Caution: Please do not touch the microphone’s front! After preparing the microphone like this, you can insert the microphone into the receptacle on the circuit board again. The white marking has to face the top. Caution: Please take care when working with the microphone as it is sensitive to pressure, dirt and moisture and has to be protected from those. Don’t touch the microphone’s front! 15 Battery Regulation In connection with the sale of devices that need batteries or rechargeable batteries, we are obliged to give you the following information: The new regulation obliges battery manufacturers and importers to take back, sort and dispose of all old batteries. The consumer is obliged to give back used batteries in retail stores or in municipal collection points. You can send batteries via sufficient stamped mail back to the retail store. Information in this manual is subject to technical changes. Distribution by: microelectronic VOLKMANN In der Gebhardsösch 9 D-78467 Konstanz Tel.
