To fully access all the features of your 4U40 cord-free headset,
please read this User's Guide thoroughly.
The 4U40 cord-free headset combines a unique headset and a
pocket-sized remote with all the features of a traditional cordless
phone for superior hands-free communication.
The 4U40 cord-free headset may be worn two ways: As a
super lightweight Over-the Ear model or as an ultra-stable
Over-the-Head model. Both allow for hands-free operation
and maximum mobility.
True compander circuitry virtually eliminates background
noise; and the forty-channel range of the 4U40 cord-free
headset insures the best possible reception in a variety of
calling situations.
The automatic digital security code feature of the 4U40 cordfree headset protects your equipment against unauthorized use
and against misbilled calls resulting from the activation of your
unit by other remote equipment. This feature automatically locks
your phone when the electronic remote is in the base unit.
