General Troubleshooting

This section presents problems, likely causes, and corrective actions. Problems are 
presented as follows:

❑

 — Prevent use of the system or access to common functions.

❑

 — Prevent you from making calls successfully.

❑

Prevent you from using basic calling functions.

❑

 — Detract from the user experience.

This section describes problems that prevent normal use of the system. They may 
also mask other problems. For example, if the system is not able to make a call and 
there are no batteries in the remote, you will need to install new batteries before 
you are able to determine whether the system can make calls.

The system does not 
respond in any way.

position.

the system.

the system and plugging in a lamp, 
radio, or other small appliance. If it 
does not operate, connect the system 
to a different outlet.

not operating properly.

Check the power outlet by unplugging 
the system and plugging in a lamp, 
radio, or other small appliance. If it

Call Polycom Technical Support and 
arrange to return the system for 
service.
