2.1 Precautions
• Save this manual. It includes important safety information and
operating instructions. Save all instructions for future reference.
• Before using the handset, users of hearing aids should note that
radio signals can affect hearing aids and, if powerful enough, can
cause an unpleasant buzzing sound.
• Connect AC (power supply) to the desktop battery charger only to
designated power sources as marked on the product.
• Danger: Never alter the AC cord or plug. If the plug will not fit into
the outlet, have a proper outlet installed by a qualified electrician.
Improper connection increases the risk of electric shock.
• Position the electrical cord to the AC power supply where it is least
likely to be subjected to damage or stress.
• Remove the electrical cord from an outlet by pulling gently on the
AC adapter, not by pulling the cord.
