7. MISCELLANEOUS COMMENTS 
Visonic Ltd. wireless systems are very reliable and are tested to high standards. However, due to 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 occurring on or near their operating frequencies, regardless of 
the digital code used. 
B.  A receiver responds only to one transmitted signal at a time. 
C. Wireless devices should be tested regularly to determine whether there are sources of interference and to 
protect against faults. 
The user is cautioned that changes or modifications to the unit, not expressly approved by Visonic Ltd., 
could void the user’s FCC or other authority to operate the equipment.
