Setup
Connecting the Antenna

antenna in the hole on the top of the scanner and turn
the antenna clockwise to tighten.
Connecting an Outdoor Antenna
To connect an externalantenna,followtheinstallation
instructionssuppliedwiththeantenna.Use50Ohm
coaxialcable,suchasRG-58orRG-8.Forlengthsover
50feet,useRG-8low-lossdielectriccoaxialcable.If
theantennacable’sconnectordoesnothaveaBNC
connector,youwillalsoneedaBNCadapter(availableat
your local RadioShackstore).
w Warning: Use extreme caution when installing or removing
an outdoor antenna. If the antenna starts to fall, let it go! It could
contact overhead power lines. If the antenna touches a power
line, touching the antenna, mast, cable, or guy wires can cause
electrocution and death. Call the power company to remove the
antenna. DO NOT attempt to do so yourself.
Connecting a Speaker or Headphones
Youcanpluganampliedspeakerorheadphones
(notsupplied)withÇinch(3.5mm)mini-plugintothe
HEADPHONEjackonthebackofthescanner.This
automatically disconnects the internal speaker.
Note:Useanampliedspeakerwiththisscanner.Non-
ampliedspeakersdonotprovidesucientvolumefor
comfortable listening.
Listening Safely
Toprotectyourhearing,followtheseguidelines:
• Donotlistenathighvolumelevels.Extendedhigh-
volume listening can lead to permanent hearing loss.
• Setthevolumetothelowestsetting.Thenturn
onyouraudiodeviceandadjustthevolumetoa
comfortable level.
• Avoidincreasingthevolume.Yourearswilladapt
tothevolumelevel,soalevelthatdoesnotcause
discomfort could still damage your hearing.
