General

Q1 What is the range of an Anabat?

A1 The detecting distance of the Anabat (or any other bat detector for that matter), is affected by a number of factors, the most important one being the species of bat. Bats with high frequency, quiet or directional calls (such as horseshoes or long eared bats) may only be detected at distances of typically less than 5 metres. Bats with low frequency and loud calls such as Noctules and Serotines may be detected as far away as 100m or more. The detection range is therefore dependent on the sound charcteristics of the call rather than the detector, although the most receptive zone of the Anabat is within a 90 degree cone in front of the microphone.

Data analysis

Q2 The Analook programme only downloads the first call of the evening and nothing afterwards. What is wrong?

A2 Ensure that the ‘CFCRead’ programme that you use to download the data, is the same version that loaded the software and times onto the card. If you have several computers, do ensure that the same computer does the job to avoid problems.

Q3 The data produced on the Analook programme shows lots of noise all night long, all around the 15-25 kHz range.

A3 You are likely to be picking up crickets, etc. Try re-positioning the Anabat well above ground level and pointing slightly upwards so as not to pick up cricket noise at ground level.

Hardware

Q4 The Compact Flash (CF) card seems to have no data on it.

A4 Is the CFCRead programme that was used to programme the card, the same as one that has been used to retrieve the data? If the computer programme has been upgraded in between or used on a different computer with a different version of the CFCRead then it may not read the data, and the CF card may appear to have no data on it. Try using the same programme and computer that was used to programme the CF card.

Q5 My SD1 won’t turn on at all, despite having 4 new AA batteries or using a 12V supply. What is wrong?

A5 It is likely the internal battery has failed. The SD1 internal battery runs the clock and holds the programme. This battery typically lasts over 3 years. When the battery eventually fails the unit is rendered useless, as it will not switch on. This must be remedied by sending the unit back to Titley, for a battery replacement. Currently the units that typically require battery replacements are in the range of serial numbers 01000- 02000. The battery is now available in the UK, see UK Sales and Repair Service for information on how to send your Anabat to Titley Scientific UK for a new battery to be soldered in and for the firmware to be re-installed.

According to Titley Electronics the new SD2 does not suffer from this problem.

Q6 The lead that was sent with the Anabat II (and ZCAIM) unit will not fit into the computer, have I been sent the wrong lead?

A6 The lead is correct, it is the computer that doesn’t have the correct connections. You will need a computer with a serial port output; most modern laptops and new desktops do not have them fitted as standard. You will need to use an older desktop computer that has the correct connections available or fit one to your desktop. USB to serial port adaptors are readily available.

Q7 Error light shows on SD1.

A7 This light shows when there is no Compact Flash (CF) card in the card slot. It can be caused for several reasons:

  1. CF card is not inserted,
  2. CF card has not been initialised,
  3. CF card has been corrupted.
  4. CF card has been physically damaged,
  5. CF slot has been physically damaged. Try using a new CF card or send the unit for repair to the card slot.
  6. Anabat is being used with a PDA – status and error LEDs will be illuminated, this is normal.

Q8 Anabat II/ZCAIM, SD1 or SD2 unit has been subjected to water ingress (directly or by condensation)

A8 This is likely to damage the internal workings of the unit, and will need possible replacement of some electronic components. Send the unit for possible repair.
