any misuse, misapplication or damage to batteries.

designed for use with your product.
• Use of power sources not explicitly recommended may lead to
overheating, reduced battery performance, distortion of the
equipment and fire or other damages.
• Cordless phones are equipped with Nickel Metal Hydride
(NiMH) batteries or Lithium Ion Lion batteries. In a complex
infrastructure, the talk- and standby time may differ, due to the
consequence of the increase in signaling.

hours) before first time use.

pressure rupture.

become warm. This is a normal effect of charging NiMH
batteries.

do this frequently.
• Only charge the batteries when placed in the phone.
