Operation
This chapter tells you how to use the optiPoint 300 basic tele-
phone.
Basic operation
All of the optiPoint 300 basic functions are performed using the
telephone keys.
The unit can be used as a traditional telephone. Simply enter the
number you want to dial on the keypad. If you make a mistake,
erase it by pressing the
<
key. Hold the key down to erase the
complete number just entered, or to return to the start of the num-
ber.
You may also enter an IP address instead of a telephone number.
To do this, separate the three-digit groups of the address by press-
ing the asterisk separator
*
. In the display, this will show up as
the underline character _.
Specialised functions are selected using the appropriate symbol
keys. The meanings of the symbol keys depend on the context, i.e.
the operating mode of the optiPoint 300 basic.
Use the + and - keys to increment or decrement a displayed
parameter (for example, to adjust the handset volume).
