Chapter 4: Maintenance 35
CARING FOR YOUR MAX IP
• Follow all warnings and instructions marked on your MAX IP.
• Unplug base unit and conferencing pod from the wall outlet before cleaning.
• Do not use liquid or aerosol cleaners. Use a damp cloth moistened with water to clean the outside of your
conferencing pod or base unit and power supply.
TROUBLESHOOTING
If you are having trouble with your MAX IP, it might be improperly set up or other equipment might be
malfunctioning. To begin, check for the following (or consult the chart in figure 4.1):
• The MAX IP base unit is plugged into an electrical outlet with the proper voltage and its power light is on.
• Make sure cables are securely connected.
• The equipment the other party is using is comparable in quality to your MAX IP conferencing phone and is
working properly. While the MAX IP works with speakerphones, cell phones, handsets or installed
conferencing systems, the quality of the conference will be impacted if the party you are conferencing with
has poor quality equipment.
