than usual, the battery life is at an end. Replace the battery with a
new battery of the same make and specification.
Do not discard the battery with household trash. Please dispose

and guidelines.
Use manufacturer-approved batteries, chargers, accessories and
supplies. We will not be responsible for user's safety when using
unapproved batteries or accessories.
