Use batteries type UM3 (AA-Size).
Do not use old or weak batteries. The remote control may not work properly with a weak voltage from
such batteries. Replace exhausted batteries with new ones. Never try to recharge normal batteries - this
could cause an explosion.
Note:
Exhausted batteries can leak corrosive electrolyte, which may cause damage to the remote control -
therefore remove exhausted batteries immediately.
