not meet these specifications could damage the scanner or the
adaptor.
When you use a cigarette-lighter adaptor, you might hear electrical
noise from your engine while scanning. This is normal.
Connecting an earphone or headphones
For private listening, you can plug an 1/8” (3.5 mm) mini-plug
earphone or headphones (not supplied), into the headphone jack
on the front panel. This automatically disconnects the internal
speaker.
Connecting an Extension Speaker
In a noisy areas, or you install the scanner into your dashboard,
extension speaker (not supplied) might provide more comfortable
listening. Plug the speaker cables 1/8 inch (3.5 mm) mini-plug
into your scanners EXT-SP jack, located on the rear panel of the
radio.
Listening Safely
To protect your hearing, follow these guidelines when you use
headphones.
Do not connect headphones to the external speaker jack located
on the rear panel of the radio.
Set the volume to zero before putting on headphones. With the
headphones on, adjust the volume to a comfortable level.
Avoid increasing the volume once 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.
Traffic Safety
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!
