Detection Warnings
When entering Talk mode the
0E -TELBSET
performs several tests before
going off-hook. These tests include high and low voltage checks and data
detection. The following describes the types of warning screens that might
be encountered.
Figure 4.1
The voltage warning display screen is presented if the voltage
detected on a cable exceeds 65 volts peak AC or DC. If this screen appears,
the
0E -TELBSET
disconnects from the line and retries every few seconds.
The
0E -TELBSET
should be disconnected immediately from the source of
voltage to prevent damage.
Figure 4.2 The high current warning is displayed if the current on the
line exceeds 125mA. If this screen appears, the
0E -TELBSET
should be
disconnected immediately from the source of the current.
Figure 4.3 If a line is in use, the
0E -TELBSET
will display the line in use
screen. To connect, press the F2 soft key.
Figure 4.4 If data is found, the Data Present warning is displayed with the
measured KHz.
