About Cordless Terminals
A cordless terminal is a multifunctional terminal that interconnects its Bluetooth®Terminal
and Bluetooth®handset with each other using Bluetooth®wireless technology to maintain
calls or perform other operations between them.
・The Bluetooth®terminal can be handled the same way as a terminal. Its Bluetooth®
handset can be handled likewise, except for some of its features. If a particular feature of a
terminal does not work, use the Bluetooth® terminal to enable it.
・If the Bluetooth®handset is out of service, return it to the Bluetooth®terminal to keep it
charged at all times.
・Where multiple cordless terminals are set up, be careful to retain the pairing between the
Bluetooth® cradle and Bluetooth® handset.
The table below summarizes the key functions of a cordless terminal. For information about
the functions of the multifunctional terminal itself, refer to the manual that comes with your
system.

About Cordless Terminals
The Bluetooth®terminal and Bluetooth®handset can be separated from each other about 50m
at the farthest as a line-of-sight distance. This talking range, however, may shorten depending
on the office environment in which the Bluetooth®terminal and Bluetooth®handset are used;
for example, they are used near a metal or concrete wall.
If the handset gets too far away from the Bluetooth®cradle, the antenna mark will disappear
accompanied by an alarm tone.

About Cordless Terminals
Before you use the Bluetooth®handset for the first time or using the handset after it has been
left out of use for a long time, charge it for at least 5 hours. (Full charging takes about 16
hours to complete.) A fully charged handset will allow you to talk for about 8 hours
continuously and stand by for about 30 hours if low-power mode is enabled or for about 15
hours if low-power mode is disabled.
The remaining battery voltage icon appearing in the LCD screen, coupled by the incoming
call/charging lamp and an alarm tone, alerts you to the remaining battery voltage of the
Bluetooth®handset. The table below describes how these indications appear depending on
the remaining battery voltage of the handset.

About Cordless Terminals
The battery loaded in the Bluetooth®handset has a useful life of about 2 years, though it is a
parameter of on how the handset has been used. If the battery voltage diminishes quickly
after the battery has been charged for a long time, replace with a new battery (Li-ion
BATTERY - option). For more details, ask your dealer.
Replacing the Battery
This product is powered by a lithium-ion battery.
Lithium-ion battery:3.7V 1100mAh
The lithium-ion battery is a recyclable resource.
When recycling batteries that have been replaced or that have been taken out of a used
product, take notice of this precaution to avoid smoking and firing:
• Take proper precautions when discarding the battery. It may be considered hazardous
material in some areas.
• There is a danger of explosion if the battery is incorrectly replaced.
• Replace only with the same or equivalent type recommended by NEC. Return old
batteries to the battery supplier, a licensed battery dealer or a designated collection
facility.
• Bring batteries to our repair counter with the contacts being taped to prevent shorts or
enclosed individually in plastic bags.
