Key Battery Replacement

If the buttons on the transmitter are inoperable and the operation indicator light does not flash, the battery may be dead.

Replace with a new battery before the transmitter becomes unusable.

 

  • Make sure the battery is installed correctly. Battery leakage could occur if it is not installed correctly.

  • When replacing the battery, be careful not to touch any of the internal circuitry and electrical terminals, bend the electrical terminals, or get dirt in the transmitter as the transmitter could be damaged.

  • There is the danger of explosion if the battery is not correctly replaced.

  • Dispose of used batteries according to the following instructions.

    • Insulate the plus and minus terminals of the battery using cellophane or equivalent tape.

    • Never disassemble.

    • Never throw the battery into fire or water.

    • Never deform or crush.

  • Replace only with the same type battery (CR2032 or equivalent).
