Starting Operation
A very large rechargeable battery will prevent the battery cover (5) from closing. In this case, the battery cover can be removed.
Push the two hinges inwards against the spring force. Remove the battery cover. There is no IP protection whilst the battery cover is not in place!
To refit the battery cover, push the two hinges inwards against the spring force again. Place the battery cover on the housing. Allow the two hinge pins to engage in the openings on the housing.
