SM2 Yearly Maintenance

SM2 Yearly Maintenance

If you have recorders from the Wildlife Acoustics SM2 family, there are a number of things you should do annually to make sure each is ready for the next recording season:

  • Replace the two AA batteries that run the clock with brand new alkalines. See our past blog post for a trick on how to do this
  • Check that the hex nuts that are around the outside of the various ports are hand-tight. These can sometimes get loose and will allow in water. Never use a wrench to tighten these
  • Check that the white hex shaped vent port is also hand-tight. Again, never use a wrench on this.
  • Look for any visible damage to the SD card slots
  • Look for any signs of water intrusion
  • Check the lid gasket for tears or anything that would interfere with a good seal such as pine needles
  • Update the firmware to the latest available
  • Test your microphones. Acoustic microphones can be tested by creating a manual recording and listening to it. Ultrasonic microphones should be tested using the optional Ultrasonic Calibrator tool available from Wildlife Acoustics
  • Finally, always create test recordings prior to each deployment to verify that the recorder is functioning as expected and all settings are correct.

How to keep your NiMH batteries in top shape!

How to keep your NiMH batteries in top shape!

Now is the perfect time to condition your NiMH batteries to make sure they function optimally in the upcoming recording season.

“Conditioning” is a process available on more sophisticated NiMH chargers that runs the batteries through a series of charge and recharge cycles in order to rejuvenate batteries to a state in which they can hold maximum charge.

The charger we sell on our website, the Maha MH-C808M charger, has this mode available. The Imedion line of low-self-discharge batteries that we sell are recommended to be conditioned after 10 normal charges, or on batteries that have been infrequently used. Please check the manufacturer’s recommendations if you are using another brand of battery.

Support Desk: Resolving Song Scope Licensing Issue on Macs


On your Mac, your Song Scope software suddenly asks you to activate it again, even though it previously worked fine and there has been no obvious change to cause this.

What's going on:

When you activate SongScope software, your copy is tied to both the currently logged in user and the current machine name. With some Macs which are on company or university networks, the machine name is dynamic and will change over time. In technical terms, the name is being assigned by the DHCP server. This causes our licensing to fail since the machine name at the time of activation is not the same as the current machine name.

How to fix it:

To resolve the issue, you will need to work with your network administrator to have your computer name fixed and not be dynamic. If you can have it fixed to the same name it was when you activated, then it should automatically work again. If the name is different than when you first activated, you will need to contact Wildlife Acoustics via our support email address and send us information on the situation and your serial number. We can then assist in getting the situation straightened out.
