Type
A
Associated equipment
B
Broadcast equipment
C
Radio-sensitive equipment
D
Low-immunity equipment
Answer Notes
In the context of Industry Canada's (ISED) EMCAB-2 bulletin, a garage door opener is legally classified as 'radio-sensitive equipment'. This term refers to consumer electronic devices that are not primarily intended to receive radio communications but can still be unintentionally affected by strong local RF fields.
Using the correct regulatory terminology is crucial for this exam. While it might seem logical to describe a garage door opener as having 'low immunity' because it easily picks up interference, EMCAB-2 specifically groups items like electronic organs, home alarm systems, and garage door openers under the formal definition of radio-sensitive equipment.
The distractors 'associated equipment' and 'broadcast equipment' are completely different classes of gear. Associated equipment generally refers to peripherals tied to a radio transmitter, and broadcast equipment refers to commercial radio or television transmission gear, neither of which applies to a neighbor's household electronics.
