Making Calls and Testing
Issue 2 - 05/00 6 - 7
Each box on the screen represents a B channel. An empty
box indicates that there is no call in progress. A loopback
arrow in a box indicates that a call has been established
and the loop applied.
The LED indicators show which B-channels are in use.
Any active calls are cleared down after exiting from
Unattended mode. The B1 and B2 LED indicators will be
illuminated if there are any active calls.
Choose F6 to exit and clear all current calls. A remote
clear on one B-channel will cause an unattended
aurora
Duet
to clear the other channel.
The automatic power-off facility that normally turns off
aurora
Duet after a short period of no activity is disabled in
Unattended mode. This allows operation until the battery
is discharged (should no external power source be
available).
