Over time electronic switch contacts can deteriorate (especially in outdoor devices such as trail cameras) and so not operate correctly, in 95% of cases some electronic switch cleaner can be applied and this will clean and rejuvenate the contacts and fix the problem. With regards to a Ltl Acorn trail camera, this could exhibit symptoms such as the camera operating as if it is in ON mode when in fact the switch is set to TEST mode, LCD screen not coming on in TEST mode, or perhaps the camera not working at all.
We use Caig DeOxit D5 to help dissolve corrosion and improve the connections of the switch contacts.
A small spray of the switch cleaner should be applied to the TEST/ON/OFF switch with the switch in the ON position (using the straw/pipe supplied with the Caig DeOxit D5 can), then move the switch slowly between each different setting about 20 times to allow the cleaning fluid to find it’s way to all parts of the switch & contacts. Leave the ltl acorn camera standing upside down, so that the switch is pointing upwards, for a few hours (indoors of course!).
The above should be carried out indoors and without any batteries or SD card inside the ltl acorn camera!
After around 3-4 hours have passed, try the trail camera again. Make sure you are using fully charged or new batteries (must be at least 2500mA output current) and a fresh SD card that has been formatted in your PC.
If the above procedure does not fix your Ltl Acorn wildlife camera then it’s a good idea to give the process a second try just in case the switch contacts were particularly dirty and require a second clean.
