Troubleshooting
If you experience difficulties with the operation of your videophone, we recommend
the following course of action.
• Check all the connections and verify the basic operation of the components of the
installation, power to the system and your network.
• Review this User Guide to verify the proper setup and operation of the system.
• Consult the following table which describes some of the most common
difficulties encountered with the operation of the unit, and follow any relevant
advice for solving your problem.
• Carefully check the power and wiring for all external cameras used in the system
and any other peripheral or video monitor used. Many typical problems, not
described below, are usually related to faults with the additional equipment
which comprise a complete installation or when this equipment is configured
incorrectly.
• If your problem is still not resolved, contact Black Box Technical Support. Refer
to the Product Support page at the front of this User Guide.
