the device to alter its behavior to regulate its
temperature.
Store the device where the temperature is
between -5ºC and 30º C (23ºF to 86º F). Don’t

Taking Care of the Sonar:
1. After retrieving the sonar from the water,
simply pull up the rubber skin with your
hands/fingers so that it is back to its original
place. Since the sonar is wet, it should be easy
to pull the skin up.
2. Next, rinse the sonar with fresh water
(especially if the sonar has been deployed in
salty water).
3. Make sure the 3 tiny stainless steel pads on
the bottom of the sonar are completely clean and
shiny, and do not have any salt residues on
them.
