Battery disposal and replacement
Batteries must not be disposed of as ordinary refuse. Please use a local battery recycler.
Replacement batteries are available from Rotronic. These are Lithium rechargeable batteries and must only be replaced with the same type. The replacement battery will be supplied with plastic tweezers; do not use a metal tool to remove the battery as this will cause a short circuit. Be sure to insert the new battery using the correct polarity as shown.
Use of a non-rechargeable battery, or incorrectly inserting the battery could lead to explosion.
