1.9.5 Keep track of the lines and extensions

To keep track of the extensions and the lines connected to each unit, label
each unit with its unit ID. It simplifies matters when you need to add or
remove extensions and lines.
If the units are located in a room away from the extensions and you need to
identify the units, the View System Information utility in the configuration
software allows you to identify each unit as follows:
1. Open the TalkSwitch configuration software.
2. Click the View System Information link below the TalkSwitch image. See
Figure 26.
3. Select the Unit ID to verify.
4. Click the Identify button and observe the flashing LEDs. The lights stop
flashing when you click the Close button or when 5 minutes have
elapsed.
