BATZ 2.0 (CE10504)
ciel EaM Manual
V4.0.0.E
Thank you very much for buying a ciel EaM bat detector. Warning notes: - A bat detector is not a toy - Danger of choking ! Small parts. Not suitable for children under 3 years! - Loud noises, especially on headphones, may damage your ears ! - Never use the detector with headphones near any hazardous places (traffic etc.), as you might not be aware of any upcoming danger.
Functions of the detector: A Microphone – The electret microphone is very sensitive to ultrasonic calls, it is mechanically robust and water resistant but not waterproof. To prevent the microphone from being damaged avoid direct contact to water or any other fluids. B Display – The frequency you have chosen will be displayed on the LED display. This will assisit you if you are looking for specific species or if you want to classify unknown calls. The display is dimmed to a low brightness to provide good readability at dawn and at night without overexerting your eyes. C Loudspeaker – For a clear reproduction of the bat calls two 0.5 watt microspeakers are integrated in the detector. D On/Off switch – Switch to turn your detector on and off. E Recording button – To start recording and playback and erase the detector's call memory. F Volume - +/- Push button to set the volume to the level required. G Thumbwheel – To set the frequency of the HD detector. H Strap – To protect your detector from falling. Rear side – battery compartment – Please take care of the polarity of the battery. If the device is not used for a long period of time please remove the battery frrom the compartment.
General information about your detector: The heterodyne detector (HD): A heterodyne detector works similar to a broadcast receiver. The frequency you have chosen will be subtracted from the bat call with a bandwidth of +/- 5 kHz transforming it to the audible range. As an example : Detector is set to 42 kHz Call frequency 48 kHz 47 kHz 46 kHz 45 kHz 44 kHz 43 kHz 42 kHz 41 kHz 40 kHz 39 kHz 38 kHz 37 kHz 36 kHz

You can use the HD detector like a radio and search the whole ultrasonic range for bats. A bat call has a wider range than one frequency, so you will be able to hear it across the whole 10 kHz window of the detector. When turning the thumbwheel you can now hear the frequency and the volume changing. Try find the best and loudest playback of the call. The display then shows the peak frequency of the call. Ultrasonic sources which emit single frequency sine or square wave signals will be heard on the detector as a beeping signal. If the frequency of the detector is similar to the frequency of the source there will be no audible signal at all. This is because you are subtracting the detector frequency from the source signal with the result of 0 kHz. If you now tune up or down you will hear a rising beep. Heterodyne detectors are used for manual data collection. It is the easiest way to identify species in the field depending on the quality of the call and the shown frequency. It is very difficult or even impossible to gain results as precise as these by using FD or TE detectors in the field. If you want to analyse a recorded heterodyne signal you have to know the original call frequency. The benefit of analysing software is very limited with HD recordings.
First steps: Open the battery case on the rear side and place a 9 volt battery in the compartment. Please pay attention to the polarity of the battery. To turn the detector on press the On/Off button (D) until the display (B) shows '----'. Press the + button within a second to confirm this or the detector will switch off. This prevents the detector from accidentally being switched on while being carried. If the device is not used for a long period of time please remove the battery from the compartment. Setting the volume: After switching the detector on the volume is set to midscale. Use the buttons + and – (F) to set the volume to the level required. The setting applies to all modes. You may change the volume at any time. Setting the frequency: The call frequency is selected by the thumbwheel (G) on the right side. The lowest frequency is 18 kHz, the maximum is 130 kHz. For technical reasons the upper maximum may be exceeded. To give you the best resolution and to compensate for fluctuations of temperature and voltage the HD mode will be recalibrated every time the detector is switched on or switched into HD or TE mode. A battery can be used until it's end of life. Testing your detector: You can test your detector by setting the detector to a low frequency up to 25 kHz and rub your fingers ~30cm from the microphone. You should now hear this noise very clearly on the headphones. If you notice other noises you may check your surrounding area for other ultrasonic sources like energy saving lamps, neon lamp starters or switching power supplies. Influences on the reception of the detector: Bat calls can be very different depending on species and the surrounding enviroment. Some species call in the lower, energy-rich ultrasonic range and can be easier to hear than species which call in the upper band. Bats adapt their calls depending on the habitat. In an open area with few or no obstacles the calls are louder but more rare than in a thick forest. The reception is also affected by the distance to the bat, flight direction and atmospheric conditions. The higher the frequency of the call, the more
atmospheric absorption will occur. High humidity will also raise the absorption level. Recording/Playback of a call: Push the button Rec (E) in HD mode to record a call. The recording will start immediately and the memory LED on the upper left side of the display will begin to flash. The signal of the HD detector will now be recorded with 44.1 kHz sampling rate in 8 bit mode. The recording length is ~3 seconds. You cannot switch to another detector mode during the recording. When the recording is finished the memory LED will be constantly on. The push button Rec (E) will now work as a playback button. Press it for less than 3 seconds to playback the call. The display now shows the frequency that was selected at the time the recording was made. This frequency is taken at the start of the recording. Adjustments made while the recording was running are not displayed. Deleting a recording: To delete a recording hold the Rec Button (E) for 3 seconds or longer. The detector will confirm the deletion by showing 'del' in the display. The memory LED will switch off and the detector is now ready for a new recording. Only one recording at a time can be held. The recording is saved in a volatile memory and will also be deleted if the detector is switched off. Switching the detector off: Press the On/Off button for 3 seconds or longer. The device will confirm this with 'OFF' on the display. Battery lifetime: The detector is fully functional until the battery reaches 6.7 volts. When the battery life is at an end with 7.2 volts or less the display shows 'LBAT' when switching on. Nevertheless the detector stays operable. When the battery reaches 6.7 volts, the HD reception will begin to fade. Please exchange the battery. Please use only alkaline 9 volt batteries or 8.4 volts (7 cells) or 9.6 volts (8 cells) NiMh rechargeable batteries. If you have any questions or problems please contact us
