Important Care & Precautions:
Before connecting or using your new phone, take a moment to consider safety and reliability.
Use common sense when locating, connecting and using your GDC-480H
 The GDC-480H uses 3.7 VDC Li-ion batteries. Replace batteries only with identical
size and type available from your local Ericsson-LG Enterprise dealer. Use of a
different battery type may cause damage to the phone or charger and may cause fire or
explosion. Dispose of batteries in accordance with any local codes or regulation.
 The Chargerbase unit should only be used on a dry level surface. Keep the
Chargerbase away from the edges of the surface to avoid the potential of a fall.
 Avoid situations where you might drop the handset. While the GDC-480H is a rugged
mobile device, dropping it on to the floor may cause critical damage.
 Locate cables to avoid potential for damage. For example, do not place under rugs or
carpet as damage may result from foot traffic or heavy objects. Also, do not locate
cables between the desktop and walls where they may be crushed, damaging the
insulation.
 Check cables regularly, and if damage is noted, disconnect your phone. Contact your
local representative for a replacement.
 Should liquid spill on the handset, remove the batteries and dry with a soft cloth.
 Do not use during lightning storms. Lightning presents a potential shock hazard.
 Clean the GDC-480H with a soft dry cloth; do not use liquid cleaners.
 Always use caution when connecting to AC power. Use only with a properly grounded
standard AC power outlet.

1. Introduction
Thank you for selecting the Ericsson-LG Enterprise GDC-480H Wireless handset. With our
GDC-480H you will experience great in-building mobility with access to all of the many
features and functions of your Ericsson-LG Enterprise communication system. This guide is
intended to provide you with detailed information on the use of your new Ericsson-LG
Enterprise Wireless DECT handset.
GDC-480H is a wireless handset that employs DECT technology to provide local in-building
mobility. Wireless Radio Frequencies (RF) signals are exchanged between the handset and
base stations (GDC-400B600B600BE). Multiple base stations connect to the Wireless
Management Interface (WMI) in your Ericsson-LG Enterprise phone system. The WMI links
the connected base stations forming a larger Base or Zone. Within this zone, transparent
handover of active communications between base stations in the zone is supported.
The button and features are almost same between GDC-480H and GDC-. But GDC-480H
does not support Bluetooth feature and the model name is different.
1.1 Description
1.1.1 Handset
The GDC-480H, shown in the Handset Diagram, appears much like a mobile cell phone. On
the front are the dial pad, a number of control buttons (described in the Handset Buttons and
Features list) and a large LCD display. In the lower rear of the unit is the battery
compartment. The battery charging terminals are located at the bottom of the unit. On the
right side of the GDC-480H is the headset jack.
