1.1.3 Charger/base Unit
The Charger/base unit (p/n GDC-450SSC) is used to charge the GDC-480H/500H handset
and to house the handset when not in use. Terminals in the charger mate to terminals in the
bottom of the handset to allow the batteries to charge. Fully charged batteries provide about
12 hours of talk-time or about 80 hours of standby-time. To fully charge “dead” batteries
requires about 6 hours in the Charger.
