FEATURES

Your RadioShack ET-928 Digital

just about anywhere in your home or

you connect a headset to the hand­set for hands-free conversation —

the yard or garage.

Important:

• Cordless phones such as this one
require AC power to operate. W hen
AC power is off, you canno t dial out
or receive incoming ca lls using your
ET-928. For this reason, the ET-928
should not be your only telephone.
To be safe, you should al so have a
phone that does not require AC
power to operate (not a cordless
phone), so you can still make and
receive calls if there is an AC power
failure.

• Some cordless phones operate at
frequencies that might cause inter­ference to nearby TVs and VCRs.
To minimize or prevent such interfer­ence, the base of the cordless
phone should not be p laced near or
on top of a TV or VCR.
