Connecting the Antenna

To attach the supplied flexible 
antenna:

1.

  Align the slots around the 

antenna’s connector with the tabs 
on the antenna jack. 

2.

  Press the antenna down over the 

jack.

.

  Turn the antenna’s base clockwise 

until it locks into place.

Connecting an Outdoor Antenna

To connect an external antenna, 
follow the installation instructions 
supplied with the antenna. Use 50-
ohm coaxial cable to connect your 
scanner to the outdoor antenna. 
For lengths between 50 and 100 
feet, use RG-8X low-loss dielectric 
coaxial cable. For lengths over 100 
feet, use RG8.

 

You also may need a 

BNC adapter (available at your local 

RadioShack

 store).

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 Headphones

For private listening, you can plug an 

Ç

inch (3.5-mm) 

mini-plug earphone or headphones (not supplied), into 
the 

HEADPHONE

 jack  

on the top of 
the scanner. This 
automatically 
disconnects the internal 
speaker.

Listening Safely

Do not wear headphones, earphones, or earbuds while 
operating a motor vehicle or riding a bicycle. This can 
create a traffic hazard and could be illegal in some 
areas. 

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.

Connecting an Extension Speaker

In a noisy area, an amplified extension speaker 
(available from your local RadioShack store or 
www.RadioShack.com), might provide more comfortable 
listening. Plug the speaker cable’s 

Ç

 inch (3.5 mm) 

miniplug into your scanner’s 

HEADPHONE

 jack.

Note:

 Use an amplified speaker with this scanner. 

Non-amplified speakers do not provide sufficient 
volume for comfortable listening.

Attaching/Removing the Belt Clip

You can attach the belt clip to the back 
of the scanner for hands-free carrying. 

Slide the supplied belt clip down on the 
back of the scanner. To remove the belt 
clip, pull the tab out and slide the clip 
upward.
