IV. Replacing the Compass Illuminator Batteries (OS 36/54)
Batteries are included and pre-installed in your Offshore binocular. When it becomes necessary to
replace them, unscrew the battery cover with a coin or screwdriver and replace the batteries with the
same type, a pair of alkaline #186 / LR43 , or silver oxide #389 / SR54 batteries. Be sure to install
the batteries in the same direction as the originals, with the fl at positive (+) side facing up towards
the cover on both batteries, and also check that the metal clip is over the positive (+) end of the top
battery as shown. Screw the battery cover back on tightly and press the compass illuminator switch
to test the light-a red glow should be visible around the compass (you may need to cover the right
objective lens if you are outside in bright light).
