Precautions for users of implanted cardiac pacemakers
Cardiac pacemakers (applies only to digital cordless telephones):
Wireless Technology Research, LLC (WTR), an independent research entity, led a multidisciplinary evaluation of the interference between portable wireless telephones and implanted cardiac pacemakers. Supported by the U.S. Food and Drug Administration, WTR recommends to physicians that:
Pacemaker patients
Should keep wireless telephones at least six inches from the pacemaker.
Should NOT place wireless telephones directly over the pacemaker, such as in a breast pocket, when it is turned ON.
Should use the wireless telephone at the ear opposite the pacemaker. WTR’s evaluation did not identify any risk to bystanders with pacemakers from other persons
using wireless telephones.
Operating range
This cordless telephone operates with the maximum power allowed by the Federal Communications Commission (FCC). Even so, this handset and telephone base can communicate over only a certain distance - which can vary with the locations of the telephone base and handset, the weather, and the layout of your home or office.

If there is a call while the handset is out of range, it might not ring, or if it does ring, the call might not connect well when you press 
/FLASH. Move closer to the telephone base, then press 
/FLASH to answer the call.
If the handset moves out of range during a telephone conversation, there might be interference.
