Product Information
Wireless systems are reliable and tested to high 
standards. However, due to their transmitting 
power and range, there are some limitations to 
be considered:
• Receivers may be blocked by radio signals 
occurring on or near operating frequencies, 
regardless of the code selected.
• A receiver can only respond to one transmitted 
signal at a time.
• Wireless equipment should be tested regularly 
to determine whether there are sources of 
interference and to protect against faults.
