4. SPECIAL COMMENTS
4.1 Product Limitations
Visonic Ltd. wireless systems are very reliable and are tested to
high standards. However, due to their low transmitting power and
limited range (required by FCC and other regulatory authorities),
there are some limitations to be considered:
A. Receivers may be blocked by radio signals on or near their
operating frequencies, regardless of the code selected.
B. A receiver can only respond to one signal at a time.
C. Wireless equipment should be tested regularly to determine
whether there are sources of interference and to protect
against faults.
D. Even the most sophisticated detectors can sometimes be
defeated or may fail to warn due to: DC power failure /
improper connection, malicious masking of the lens,
tampering with the optical system, decreased sensitivity in
ambient temperatures near that of the human body and
unexpected failure of a component part.
The above list includes the most common reasons for failure
to detect intrusion, but is by no means comprehensive. It is
therefore recommended that the detector and the entire alarm
system be checked weekly, to ensure proper performance.
E. An alarm system should not be regarded as a substitute for
insurance. Home and property owners or renters should be
prudent enough to continue insuring their lives and property,
even though they are protected by an alarm system.
4.2 Compliance with Standards
The 315 MHz version of 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.
WARNING! Changes or modifications to this unit not expressly
approved by the party responsible for compliance could void
the user's authority to operate the equipment.
D-302924
The digital circuit of this device has been tested and found to
comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in residential
installations. 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 and television reception. However, there is no guarantee
that interference will not occur in a particular installation. If this
device does cause such interference, which can be verified by
turning the device off and on, the user is encouraged to eliminate
the interference by one or more of the following measures:
– Re-orient or re-locate the receiving antenna.
– Increase the distance between the device and the receiver.
– Connect the device to an outlet on a circuit different from the
one which supplies power to the receiver.
– Consult the dealer or an experienced radio/TV technician.
