The SM4 is designed with all kinds of weather in mind
and will not let in any water under normal circumstances. A few routine checks and best
practices will keep your recorder as weatherproof as it was when it was
brand-new.
About this task
- Ensure that the built-in microphones on a (non-bat, non-ultrasonic) SM4 are
hand-tightened and that the wires connecting these microphones to the SM4's
motherboard are tucked into place so they won't get wedged in between two
sections of the SM4 housing. This is particularly important to keep in mind when
installing replacement microphones on an SM4.
Procedure
-
Periodically, examine the black rubber gaskets around the edge of the control
panel for debris and tears.
Wildlife Acoustics sells self-adhesive replacement gaskets.
-
Avoid exposing the SM4 to DEET (a common
ingredient in insect repellent), and gently clean the recorder on a regular
basis.
Long exposure to DEET and some plant oils can degrade the recorder's plastic
body or rubber gaskets.
-
Avoid using excess tension when mounting the Song Meter SM4 using
a rope, strap, or cable lock.
Excess force can bend the recorder's enclosure, causing it to open
slightly.
Note that fast-growing trees put additional strain on the recorder over a
long-enough deployment.
-
Ensure the hexagonal pressure vent on the right side of the recorder and the
nuts holding the microphones in place are hand-tightened and undamaged.
Pressure vents can be purchased from our sales team. To get any damaged
microphone ports repaired, please contact our support team.
-
Check that the built-in stub microphones are hand-tightened and that the wires
connecting these microphones to the SM4's
motherboard are tucked into place and will not be caught against the housing
gasket.
