Introduction

General DECT Handset Information Guide
G355, G955 and I755 Basic User Manual
NEC Digital Enhanced Cordless Telecommunications (DECT)
G355, G955 and I755 Handsets are cordless phones with
enhanced features.
The G355 and G955 are suitable for office use.
The I755 DECT Handset complies with IP54 –according to IEC
529 / EN 60529 and thereby offers more sturdiness. The I755 is
therefore suitable for industrial and healthcare environments.
NEC G355, G955 and I755 DECT Handsets are compatible both
with traditional DECT and IP DECT systems.
The G355, G955 and I755 DECT handsets should only be used in
combination with DECT systems delivered by NEC. In order to
take advantage of all features the country and network provider
specific features should match the features of the NEC system.

Use in environments with metal particles
G355 and G955
The G355 and G955 DECT Handsets are not meant for use in
industrial and/or production environments. Using the G355 and
G955 DECT Handset in environments with metal particles will
cause small metal particles to stick to the loudspeaker and to the
earpiece. This will have a deteriorating effect on the quality of the
speech as heard by the user of the DECT Handset.
I755
The I755 DECT Handset makes use of inductive charging.
Because of this the I755 is at some places very magnetic and it
will therefore attract metal objects. Metal particles might stick to
the I755; this will not affect the operation. Nevertheless NEC
strongly recommends using a protective pouch for the I755 DECT
handset when it is used in an environment with small metal
particles.

Battery and charger information
10
Battery and charger information
The G355, G955 and I755 DECT Handsets use rechargeable
Lithium-Ion (3.7V, 650 mAh, 2.4 WH) battery packs. Only use
batteries that come with the handset or dedicated spare batteries
marked with “Battery Pack for G355/G955” or “Battery Pack for
I755” for the G355/G955 resp. the I755 handset. Do not use any
other type.
Charge the batteries of the G355 and G955 handset only in
combination with either:

MEM card installation
The G355, G955 and I755 DECT Handsets can be equipped with
a removable memory (MEM) card used to store configuration and
user data on. The MEM card allows for:
1. Storage of more data than in just the handset’s memory;
2. Transfer the configuration and user data from one handset
to another (e.g., in case a handset becomes defective).
When an empty MEM card is inserted, the configuration of the
handset is copied to the MEM card. Note that the DECT
subscriptions of the handset are also moved to the MEM card.
When you therefore remove the MEM card from the handset you
won’t be able to make or receive calls with your handset.
When inserting a MEM card with the configuration of some other
G355, G955 or I755 DECT Handset then that configuration will
be used.
Any configuration changes or new contacts, messages, calendar
items and call filter items added after installing a MEM card are
stored on the MEM card and not in the handset memory.
The MEM card tray is under the battery pack on the back of the
handset. Therefore before you can install or remove the MEM
card the battery pack has to be removed from the handset.
Reinstall the battery pack after you have installed or removed the
MEM card.
Note: To install a new MEM card into the handset, you must
extract it from the frame it comes in.
Installing the MEM card
To install the MEM card in the handset, perform the following
steps:
1. Place the handset facedown on a flat surface.

and press it, as shown in Figure 1.
4. Ensure that you have inserted the MEM card completely.
5. Replace the battery pack.
6. G355 and G955: Replace the battery compartment cover.

Bluetooth module installation
15
Bluetooth module installation
The G955 and I755 DECT Handsets can be equipped with a radio
system to support Bluetooth wireless technology enabled
headsets.
The Bluetooth module “dock” is located under the battery pack on
the back of the handset. Therefore before you can install or
remove the Bluetooth module the battery pack has to be removed
from the handset. Reinstall the battery pack after you have
installed or removed the Bluetooth module.
Installing the Bluetooth module
The Bluetooth module is supplied in an ESD bag and comes
complete with a Quick (Installation) Guide.
To install the Bluetooth module in a G955 or I755 DECT
Handset, perform the following steps:
1. Place the handset facedown on a flat surface.
2. G955: Remove the battery compartment cover.
3. Remove the battery pack.
4. Slide the Bluetooth module into the Bluetooth
compartment as shown in Figure 3 and click the Bluetooth
module firmly into place.
5. Replace the battery pack.

DECT system configuration
Subscribing the handset to a DECT system
The handset has to be subscribed to at least one DECT system
before it can be used to make a call. The handset can operate with
a maximum of four (with a MEM card: eight) DECT systems, for
which the handset stores the name of the system in a subscription
record. The subscribed name appears on the handset display
whenever the handset enters the range of the DECT system.
To subscribe to a DECT system you need the following
information:
1. PARK code: A unique identifier of the DECT system.
Use a PARK code during the subscription procedure only
if more than one DECT system overlaps in your location.
2. DECT system name: The name of the system to which
the handset is subscribed.
3. Phone number: The local phone number of the DECT
handset.
