Warning
Use of a different type of battery than that specified here may
present a risk of fire or explosion.
Battery may explode if mistreated. Do not recharge,
disassemble, heat above 100°C (212°F), or incinerate.
Caution
To avoid damage from electrostatic discharge, use proper precautions
when performing these procedures:
â–ª Wear a properly functioning antistatic strap and be sure that you are
fully grounded. Never touch the printed circuit board, or components
on the board, unless you are wearing an antistatic strap.
â–ª Any surface upon which you place the unprotected circuit board
should be static-safe, facilitated by antistatic mats if possible.
Extra caution should be taken in cold, dry weather, when static charges can
easily build up.
