Battery level
– Battery is low. The battery should be
recharged.
– Battery is charging (the bar scrolls
until it is fully charged). The outlet
plug icon indicates that the commu-
nicator is connected to an external
power source (usually a wall outlet).
– Battery is fully charged (five bars
displayed).
Field strength
– The communicator is connected to a
cellular network. When all five indi-
cator bars are shown, radio signal
reception is good. If the signal
strength is not good, you can try to
improve reception by moving the
phone slightly or by using the com-
municator in the handsfree mode.
– The phone interface is on, but the
communicator is outside of a net-
work coverage area.
– The phone interface is off. The commu-
nicator cannot send or receive calls or
messages (via either interface).
Keyboard
In addition to the normal character and number
keys, the keyboard has several special keys, as
shown in figure 2-11.
1. Application buttons
The row of buttons at the top of the keyboard
(starting from Tel.) activate the corresponding
applications.
2. Escape (ESC)
To cancel an action, you can either press Cancel
or the escape key. The escape key can only be
used when Cancel is among the available com-
mands. All information notes shown on the dis-
play can also be dismissed with the escape key
(instead of pressing the OK command).
3. Tabulator
In editors, the tabulator key moves the cursor to
the next tabulator stop. In settings etc., the tab-
ulator key can be used to move to the next field.
