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!

POWER SOURCES

You can power your scanner from any of these sources:Ô

•Internal non-rechargeable batteries or rechargeable batteries (not supplied – see “Using Batteries” on

Page 25).

•Standard AC power (with an optional AC adapter – see “Using AC Power” on Page 27).

•Vehicle power (with an optional DC adapter – see “Using Vehicle Battery Power” on Page 28).

USING BATTERIES

You can power the scanner with four AA batteries (not supplied).

Ô NOTES Ô

•Connecting an AC or DC adapter to the scanner disconnects internal batteries when you use the supplied non- rechargeable battery holder, but it does not disconnect internal batteries when you use the supplied yellow rechargeable battery holder.

•If you install the yellow rechargeable battery holder, you can operate the scanner and recharge the rechargeable batteries at the same time. See “Using Batteries” on

Page 25, and “Charging Rechargeable Batteries” on Page 27.

•If the scanner stops working properly after connecting it to power, try resetting it. See “Resetting / Initializing the Scanner” on

Page 108.

•You must charge rechargeable batteries before you use them the first time.
