Security
The upper-left and upper-right corners of the Song Meter Mini 2 enclosure feature loops through which a cable lock can be threaded to secure the recorder to a tree or structure. The diameter of the cable must be narrower than 0.420 in. (10.67 mm) to fit through these loops.
To keep the Song Meter Mini 2 enclosure locked closed, a padlock can be inserted in the loop on the right side of the latch. The internal diameter of this padlock loop is 0.268 in. (6.81 mm). We recommend a padlock with a shackle diameter of 0.25 in. (6.35 mm). This size does allow some movement of the latch, but not enough that it compromises the IP67 weatherproof rating of the Song Meter Mini 2 enclosure.
Do not use a padlock with a shackle thinner than 0.25 in. (6.35 mm). A thinner shackle will allow the latch to be undone partially or completely, allowing water to get in, or allowing the enclosure to be fully opened.
Note that damage to any part of the Song Meter Mini 2 's plastic enclosure can compromise the effectiveness of these security features. If your recorder has been damaged, contact Wildlife Acoustics Support to arrange a repair.
