2 parallel working ways of detection
1. manually operated: mixer mode (Heterodyne)
2. automatically operated: scanner with frequency
indicator and spectrogram of bat calls (frequency
devisor) – so no bat call gets lost anymore!
Applicable for expert as well as for beginners
Frequency range 15 kHz to 130 kHz infinitely
adjustable in steps of 1 kHz
Continuous display of maximum values while scanning, ideal for easy bat detection
Up to 4 fixed frequency programmable for fast
accessing of known bat species
Easy to handle, adjustments are saved
Very good sensibility, because of special ultrasonic
microphone in combination with a high quality preamplifier stage
High quality of sound and volume, brilliant clear
and differentiated transfer of bat call through integrated 1,5 W speaker
Modern microprocessor technology, LCD with
adjustable backlight (which can be switched off)
Auto shut-off for battery protection (adjustable from
1 min to ∞)

Disposal of electrical and electronic products
The implementation of European law in national laws and directives obliges you to dispose of consumable goods appropriately. This serves to protect both persons and the environment.
Batteries, electrical and electronic products no longer required must be disposed of separate from domestic waste. For proper treatment, recovery and recycling of old products and used batteries, please
take them to a suitable collection point provided by public waste authorities, in accordance with your
national legislation and the directive 2002/96/EC and 2006/66/EC.
For more information about collection and recycling of old products and batteries please contact your
local municipality or your waste disposal service. Alternatively you can send your old SSF2 detector via
sufficient stamped mail back to:
BUND Naturschutzzentrum Westlicher Hegau
Erwin-Dietrich-Str. 3
D-78244 Gottmadingen
Information on disposal in other countries outside the European Union: If you wish to discard your SSF2

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

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.

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: bestellung@all-about-bats.net .
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
info@mekv.de
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.

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!

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.

Batteries, which contain pollutants, are marked with the symbol of a crossedout dustbin, similar to the symbol in the illustration. The chemical description
of the pollutant is situated below the symbol of the dustbin. “Cd” stands for
Cadmium, “Pb” for Lead, “Hg” for Mercury.
