WARNING: Outdoor antennas must be properly
grounded to prevent static buildup and lightning
damage. Article 810 of the National Electrical Code,
ANSI/NFPA 70, provides information about proper
grounding of the antenna mast, connection of coaxial
cable to an lightning arrestor, size of grounding
conductors, location of the lightning arrestor and
connection of grounding conductors to grounding
electrodes.
Disconnect your radio from the outdoor antenna during
electrical storm activity to prevent damage.
Headphones and Speakers
You can plug headphones (not supplied) or an amplified
speaker (not supplied) with a 1/8 inch (3.5mm) stereo
mini-plug in the headphone jack on top of your scanner.
This automatically disconnects the internal speaker.
NOTE: Use an amplified speaker; a non-amplified
speaker may not provide sufficient volume for
comfortable listening.
Listening Safely
To protect your hearing, follow these guidelines when
you use headphones:
• Set the volume to zero before putting on
headphones. With the headphones on, adjust the
volume to a comfortable level.
• Avoid increasing the volume after you set it. Over
time, your sensitivity to a volume level decreases,
so volume levels that do not cause discomfort might
damage your hearing. Avoid or limit listening at
high-volume levels. Prolonged exposure to high-
volume levels can cause permanent hearing loss.
• Wearing headphones while operating a motor
vehicle or riding a bicycle can create a traffic
hazard and is illegal in most areas. Even though
some headphones let you hear some outside
sounds when listening at normal volume levels,
they still can present a traffic hazard. Exercise
extreme caution!
