VTech TL86009 Cordless Telephone User Manual

Technical specifications
Telephone operating range
This cordless telephone operates within the maximum power
allowed by the Federal Communications Commission (FCC). Even
so, this handset and telephone base can communicate over
a certain distance — which can vary with the locations of the
telephone base and handset, the weather, and the construction
of your home or office.
Extended range and clarity
This telephone base comes with an antenna which gives much
better clarity and covers a longer range than before.
