you may need to obtain some information or make some changes that could be difficult
when on site.
Do NOT connect the Switch Module to the PBX or connect the digital telephone to
the Remote Module until the Setup Wizard has been run. An improperly configured
Switch Module can disable or damage the PBX line card and an improperly
