TONGUE SWITCH OPERATION:
Plug securely into camera shutter release jack. If your camera
does not accept a 2.5mm plug, you will need to splice on the
plug specific to your camera. (See connection instructions)
Route wire through or around camera helmet so that only the
switch and a small length of wire is exposed.
Set your camera to the desired operating mode ("multi-exposure"
or equivalent is recommended). Some plugs and connection schemes

Don't expose your switch to very hot or cold environments.
off your camera between dives and unplug switch while not in
use. Not doing this may shorten battery life.
The single/multiple exposure capabilities are dependent upon
your camera. Most will take a single shot with a short push and
between 1-4 shots per second if you push and hold. Be sure to
set your camera to "multiple" or equivalent setting for desired
