Caring for your Max EX

•   Follow all warnings and instructions marked on your Max EX.

•  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.

Electrical considerations

•  Use only the power adapter that comes with your conferencing phone.

Troubleshooting

If you are having trouble with your Max EX, it might be improperly set up or other 

equipment might be malfunctioning. To begin, check for the following or consult the chart

on the next page:

•  The Max EX base unit is plugged into the proper volt electrical outlet 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 EX 

conferencing phone and is working properly. While the Max EX works with speak-

erphones, 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.

FCC Part 68 Compliance

US:FBIMT01B910158015 Ringer Equivalence Number (REN): 0.1B(ac)

This equipment complies with Part 68 of FCC Rules and Technical Requirements for Telephone
Terminal Equipment published by ACTA. The marking on the base unit of this equipment contains,
among other information, the US number and ringer Equivalence Number (REN) for this equipment.
If requested, this information must be provided to your telephone company.

The REN is used to determine the quantity of devices, which may be connected to the telephone line.
Excessive RENs on the telephone line may result in the devices not ringing in response to an incom-
ing call. In most, but not all areas, the sum of the RENs should not exceed five (5.0). To be certain
of the number of devices that may be connected to the line, as determined by the total RENs, contact
the telephone company to obtain the maximum RENs for the calling area.

If this equipment causes harm to the telephone network, the telephone company will notify you in
advance that temporary discontinuance of service may be required. If advance notice is not practical,
the telephone company will notify the customer as soon as possible. Also, you will be advised of your
right to file a complaint with the FCC if you believe it is necessary.

The telephone company may make changes in its facilities, equipment, operations, or procedures that
could affect the operation of the equipment. If this happens, the telephone company will provide
advance notice for you to make the necessary modifications in order to maintain uninterrupted service.

IC Compliance

IC: 1970A-158015

Ringer Equivalence Number (REN): 0.1B(ac)

Notice

The term "IC" before the certification/registration number signifies that Industry of Canada technical
specifications were met.

This certification means that the equipment meets certain telecommunications network protective
operational and safety requirements. The Department does not guarantee the equipment will operate
to the user's satisfaction.

The REN is used to determine the quantity of devices, which may be connected to the telephone line.
Excessive RENs on the telephone line may result in the devices not ringing in response to an 
incoming call. In most, but not all areas, the sum of the RENs should not exceed five (5.0). To be 
certain of the number of devices that may be connected to the line, as determined by the total RENs,
contact the telephone company to obtain the maximum RENs for the calling area.

Before installing this equipment, users should ensure that it is permissible to be connected to the
facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. In some cases, the companies inside wiring associated with a single
line individual service may be extended by means of a certified connector assembly (telephone exten-
sion cord). The customer should be aware that compliance with the above conditions may not prevent
degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility 
designated by ClearOne Communications. Any repairs or alterations made by the user to this 
equipment, or equipment malfunctions, may give the telecommunications company cause to request
the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power 
utility, telephone lines and internal metallic water pipe system, if present, are connected together. This
precaution may be particularly important in rural areas.

Equipment and Telecommunications Equipment" 

See the enclosed Declaration of Conformity (DOC) that is enclosed with the equipment for full
details. Compliance of the equipment with the Directive is attested by the application of the CE mark
on the equipment.
