Polycom SpectraLink 8020 User Manual page 41

What is the range of the SpectraLink 8020/8030 Wireless
Telephone?
As barriers affect radio transmission, there is no single answer for this
question. Normally, you can expect the same range as with any other
wireless device. However, if your facility has metal walls or other mate-
rials that inhibit radio waves, the range will be reduced.
How do I charge the Battery Pack?
The Battery Pack in the handset may be charged in a Single or Dual
Charger without being removed from the handset by simply placing the
handset into the charger. A spare Battery Pack may be charged in the
rear bay of the Dual Charger or in a Quad Charger.
How long does the Battery Pack hold a charge?
There are three different Battery Pack models and each has a different
charge capacity. The type of Battery Pack is printed on the label.
Remove the Battery Pack and view the label to determine the type of
Battery Pack you have been issued.
