19.0 NOTES
The Personal Help Buttons and internal receiver supplied with your VRI400 are designed and tested to high
specific standards. However, due to laws of physics, vagaries of radio transmissions and the limited output
power allowed by the FCC, there are some limitations to be considered:
•
All receivers may be blocked by radio signals occurring on or near their operating frequencies,
regardless of the code selected.
•
A receiver can only respond to one transmitter signal at a time regardless of the number of codes in the
Valid Code List.
•
Wireless equipment should be tested regularly to determine if there are sources of interference and to
protect against faults.
20.0 NOTIFICATIONS
•
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation. 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 and 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:
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the equipment and receiver.
•
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
•
Consult the dealer or an experienced radio/TV technician for help.
•
Important:
Changes or modifications to this unit not expressly approved by the responsible party for
compliance may void the user’s authority to operate the equipment.
•
Infrequently used radio links should be tested regularly to protect against undetected interference or
fault.
•
A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale
distributor or dealer, and these facts should be communicated to the ultimate user.
