This PC Card must not be co-located or operated in conjunction with any antenna (other than the one furnished by Navini and included in the package) or transmitter. Use of this device in any other configuration may exceed the FCC, ETSI, or other regulatory bodies RF Exposure compliance limit. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed or used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

1) Reorient or relocate the receiving antenna, 2) Increase the separation between the equipment and the receiver, 3) Consult the dealer or an experienced radio technician for additional suggestions. FCC guidelines stipulate that the antenna should be more than 2.5 cm (1) from bystanders and 1.0 cm

(0.39) from the user. When in use, the antenna should be pointed vertically upward. When using the Remote Desktop Antenna with the PC Card, a minimum distance of 20 centimeters (8 inches) is required from the user or bystander.

Ripwave Wireless Broadband Access Card Users Guide Care and Maintenance, continued Upgrading the PC Card

If there is a problem with the Card, do not attempt to repair it yourself. Report the problem to your Service Provider.

Do not apply adhesive labels to the Card. This may cause the card to become jammed inside the card slot.

The PC Card should fit easily into the PC slot. Do not force the card into the PC slot. Forcing the card into the slot may cause damage to the connector pins.

If you are going to upgrade your computer Operating System after loading the NavDiag software, you must first uninstall NavDiag prior to upgrading the OS. Otherwise, NavDiag will not work. See Uninstall instructions in this Guide. There are two different ways to upgrade the software that makes the PC Card work. Your Service Provider may perform an over-

the-air (OTA) upgrade, where the up-to-date software files are transferred wirelessly from a Base Station to your Card; or the Provider may provide a downloadable web file or CD-ROM with software that is installed on your PC and used to upgrade the Card software. The latter method is used only if the PC Card was not inserted and on during the OTA upgrade process. The OTA upgrade is normally transparent to the user; in other words, there should be no noticeable service interruption. The web or CD upgrade comes with instructions and takes a minimal amount of time to complete. 050525_pv1.2_PC_Card_Users_Guide_40-00292-00b(4.3) Page 26 Navini Networks, Inc.
