1. Ensure that the battery is installed correctly.

   1. Remove the battery cover from the device.

   2. Install the battery. The customer warning message on the battery should be facing outwards. Note that the battery can only be successfully installed in this direction. Note: If the battery has already been installed, please remove it before re-installing it in the device.
