AC adapter, insert the AC adapter’s barrel plug into the scanner’s DC 13.8V jack. Then connect the other
end of the adapter to a standard AC outlet.
Cautions:
. You must use a Class 2 power source that supplies 13.8V DC and delivers at least 600mA. Its center tip
must be set to positive and its plug must fit the scanner’s DC 13.8V jack. Using an adapter that does not
meet these specifications could damage the scanner or the adapter.
. Always connect the AC adapter to the scanner before you connect it to AC power. When you finish,
disconnect the adapter from AC power before you disconnect it from the scanner.
Warning: To prevent electric shock, do not use the AC adapter’s polarized plug with an extension cord,
receptacle, or other outlet unless you can fully insert the blades to prevent blade exposure.
CONNECTING AN EXTENSION SPEAKER
In a noisy area, an extension speaker (not supplied), available at your local RadioShack store, might
provide more comfortable listening. Plug the speaker cable’s 1/8-inch (3.5 mm) mini-plug into your
scanner’s EXT SP jack.
CONNECTING AN EARPHONE/HEADPHONES
For private listening, you can connect an earphone or headphones with a 1/8-inch (3.5 mm) plug to the
(headphone) jack on the front of the scanner. (Your local RadioShack store carries a wide selection of
earphones and headphones). This automatically disconnects the internal speaker.
LISTENING SAFELY
To protect your hearing, follow these guidelines when you use an earphone or 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 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
Do not wear an earphone or headphones while you drive a vehicle or ride a bicycle. This can create a traffic
hazard and can be illegal in some areas. Even though some earphones and headphones let you hear
some outside sounds when you listen at normal levels, they still can present a traffic hazard.
