card remote commander
Under normal conditions, the battery will last
approximately 1 year. (The service life may be
shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the
card remote commander becomes shorter. Replace
the battery with a new CR2025 lithium battery. Use
of any other battery may present a risk of fire or
explosion.
