10 Chapter 1 What's new

20-name directory

You can store a maximum of 20 internal or external numbers in the handset directory. For more
information on the directory, refer to the T7406E Cordless Handset User Guide (NN40110-110).

Battery level indicator

The battery level indicator appears in the upper right-hand corner of the LCD. The battery level
indicator shows four levels of battery energy. The Low Battery message appears on the LCD
when there are between five and ten minutes of talking time remaining. When the battery reaches
this low energy level and you are using the handset, you hear a warning tone approximately every
40 seconds. To charge or top-up the battery, place the handset in the charging cradle. For more
information on the battery level indicator, refer to the T7406E Cordless Handset User Guide
(NN40110-110).

Base station features

This section describes some of the new T7406E base station features.

Wall- or ceiling-mountable

The base station comes with a mounting rack that you can use to attach the base station to the wall
or ceiling. For more information on how to mount the base station on the wall or ceiling, refer to
"Securing the base station mounting bracket" on page 38
38.

Colored LED status indicators

The base station has five colored LED status indicators: one to show the status of the base station,
and four to show the statuses of the handsets (one for each possible handset that you can register to
a single base station). For more information about the LED status indicators, see
overview" on page

Security and encryption

The handset security code is changed each time you place the handset in the charging cradle. Each
time you register a handset with the base station, 64-bit ETSI encryption is applied to the handset.

Antenna diversity

The base station and each handset are equipped with two antennas. Dual antennas ensure better
reception by minimizing multipath fading effects. The base station antennas pivot to allow you to
position them in the most optimum direction. Adjust the antenna for optimal transmission by
moving it through 90-degree-angle planes (for example, perpendicular to the wall, parallel to the
wall, perpendicular to the floor, parallel to the floor).
