TALK mode (o Hook) – normal operating mode
Outgoing call
When the TP09D is switched on, after pressing the o Hook key, the line
voltage is rst measured in order to prevent inadvertent occupancy of the
line when the Low Voltage Lockout is activated. If the measured line voltage
is between 2 and 75 volts, the information No line disappears and the line is
occupied. If Low Voltage Lockout is not activated (default), it can always be
used.
In this conguration, the following appears in the second line from left to right
on the display:
T For TALK mode
T or P Set dial, tone or pulse
- or I Low Voltage Lockout o or

<47 mA Current line current depen-
ding on the terminal device

Battery Display of battery capacity
+5 V Display of polarity (- or +) and three-digit display of line voltage,
max. 199 V
The display shows the rst symbol with T. This shows the status clearly. If it
was an incoming call, the connection is now established. The dial tone can
now be heard on an outgoing call.
With the TP09D, the selection type, pulse or frequency selection is selected
in the menu. Press the corresponding numeric keys to cancel the selection.
Either direct dialling – each key press is selected immediately – or block di-
alling – the digits are written to the display and then selected by SEL. Block
dialing is activated or deactivated by F2 = BLK. Dialling sequences can be
compiled and tested, pauses with F3 or Flash can be inserted.
