The conference phone does not ring when there is an incoming call.
• Make sure there is a dial tone before dialing.
• Make sure the ringer volume of the phone is not set to o (page 6).
• Make sure the DC power cable, Ethernet cable, AC power cord, and the power
adapter are plugged in properly (see page 3).
• If other telephones in your oce are having the same problem, the problem is in
the wiring or IP PBX service. Contact your service provider (charges may apply) or
system administrator.
• Other electronic products such as ham radios and other DECT phones can cause
interference with your conference phone. Try installing your conference phone as
far away as possible from these types of electronic devices.
• Unplug the AC power cord from the wall outlet. Wait for approximately 15
seconds, and then plug it back in. If you sll cannot get a dial tone, please contact
our customer service hotline designated above for assistance.
