Replacing the lithium battery
Under normal conditions, batteries 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.
