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:
- 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.
About cordless telephones
- Privacy: The same features that make a cordless telephone convenient create some limitations. Telephone calls are transmitted between the telephone base and the cordless handset by radio waves, so there is a possibility that the cordless telephone conversations could be intercepted by radio receiving equipment within range of the cordless handset. For this reason, you should not think of cordless telephone conversations as being as private as those on corded telephones.
- Electrical power: The telephone base of this cordless telephone must be connected to a working electrical outlet. The electrical outlet should not be controlled by a wall switch. Calls cannot be made from the cordless handset if the telephone base is unplugged, switched off or if the electrical power is interrupted.
- Potential TV interference: Some cordless telephones operate at frequencies that may cause interference to televisions and VCRs. To minimize or prevent such interference, do not place the telephone base of the cordless telephone near or on top of a TV or VCR. If interference is experienced, moving the cordless telephone farther away from the TV or VCR often reduces or eliminates the interference.
- Rechargeable batteries: Exercise care in handling batteries in order not to create a short circuit with conducting material such as rings, bracelets and keys. The battery or conductor may overheat and cause harm. Observe proper polarity between the battery and the battery charger.
- Nickel-metal hydride rechargeable batteries: Dispose of these batteries in a safe manner. Do not burn or puncture the battery. Like other batteries of this type, if burned or punctured, they could release caustic material which could cause injury.

Add & Register a handset
You can add new handsets (DS6401/DS640115/DS6401-16, purchased separately) to your DS6421/DS6472 telephone system, but each handset must be registered with the telephone base before use. When first purchased, each expansion handset shows Put handset on BASE to register after a battery is installed. You may need to charge the handset before registering it to the telephone base.
To register a handset
- Make sure the handset is out of the telephone base or handset charger and shows Put handset on BASE to register. Place the handset in the telephone base.
- The handset displays Registering handset… on the handset and the red IN USE light on the telephone base turns on. It takes about 90 seconds to complete the registration process. The handset displays HANDSET X Registered (X represents the registered handset number). The IN USE light on the telephone base turns off and you hear a confirmation tone from the handset when registration completes.
If registration fails, the system will automatically try to register again.
If registration fails after the third try, the handset displays Registration failed, and then Put handset on BASE to register and the telephone base beeps. This may take up to five minutes to occur.
To reset the handset, remove it from the telephone base. When the handset displays Put handset on BASE to register, try the registration process again.
- You cannot register a handset if any other system handset is in use.
If you want to replace a handset or reassign the designated handset number of a registered handset, you must deregister all handsets. Then register each handset you wish to use individually. To make deregistration easier, read all of the instructions on this page before you begin.
To deregister all handsets
- Make sure that all handsets are out of the
telephone base and handset chargers before you begin deregistration.
- Press and hold /FIND HANDSET on the telephone base for about 10 seconds until the IN USE light flashes.
- Quickly press /FIND HANDSET again. You must press /FIND HANDSET while the IN USE light is still flashing. The IN USE light flashes for about five seconds. If the light stops flashing, start again with Step 1 above.
- All system handsets show Put handset on BASE to register, and you hear a confirmation tone when deregistration completes. The deregistration process takes about 10 seconds to complete.
If deregistration fails, you may need to reset the telephone and try again.
- Press and hold OFF/CANCEL or place the handset back in the telephone base.
- Unplug the power from the telephone base, then plug it back in.
- You cannot deregister handsets if any system handset is in use.
- Even if the battery is depleted, you can still deregister the handsets by following the steps above.
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.
