GDC-450H Wireless Handset
User Guide
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-450H.
The GDC-450H uses 3.7 VDC Li-ion batteries. Replace batteries only with identical
size and type available from your local LG-Ericsson 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 Charger/base unit should only be used on a dry level surface. Keep the
Charger/base 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-450H 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-450H 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 LG-Ericsson GDC-450H Wireless handset. With our GDC-450H
you will experience great in-building mobility with access to all of the many features and
functions of your LG-Ericsson communication system. This guide is intended to provide you
with detailed information on the use of your new LG-Ericsson Wireless DECT handset.
GDC-450H 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-400B / 600B). Multiple base stations connect to the Wireless
Management Interface (WMI) in your LG-Ericsson 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.
1.1 Description
1.1.1 Handset
The GDC-450H, 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
left side of the GDC-450H is the headset jack.

If an Ear Microphone/Headset is attached to a GDC-450H, it can receive or release a call. It
is recommended to use a Headset meeting JIS C-6560 Specification. Press the button on
the Ear Microphone/Headset to receive an incoming call when ringing, and do the same
action to release the call. Making a call by using the Ear Microphone/Headset is supported,
too; press the button once on the Ear Microphone/Headset when in the idle state, then select
a number to dial from the redial list and the make the call by pressing the button.
Note:
Using a noise canceling or unidirectional Ear Microphone/Headset, with an impedance below
1 KΩ (usually is 1-2.2KΩ) may cause abnormal operation (unit may self-answer without
pressing the button when an incoming call is received, and unit may hang-up unexpectedly
while using the Ear Microphone/Headset).
