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.

Connecting Earphone,

Headphones or Speakers

For private listening, you can plug an 1/8-inch (3.5 mm)

mini-plug earphone or headphones (not supplied) in

the headphone jack on the front. This automatically

disconnects the internal speaker.

Connecting Extension Speaker

In noisy areas, or if you install the scanner in a vehicle,

an extension speaker (not supplied) may provide more

comfortable listening. Plug the speaker cable 1/8 inch

(3.5mm) mini-plug into your scanner’s 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.
