Attaching the antenna

Align the slots on the antenna’s BNC connector with the posts on the scanner’s BNC connector and

slide the antenna in place, then rotate the antenna’s BNC connector 1/4 turn clockwise until it snaps in

place.

Connecting an Optional External 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-8X, to connect an outdoor antenna.

. For lengths between 50 and 100 feet, use RG-8X low-loss dielectric coaxial cable.

. For lengths over 100 feet, use RG-8.

You also may need a BNC adapter (available at your 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.

Powering the Scanner

Installing batteries

Warning: Always power off the PRO-18 by pressing and holding POWER before removing batteries.

Failure to power off PRO-18 may cause data loss or memory corruption.

Remove the door covering the battery compartment by pressing gently where the door is marked

OPEN and sliding the door downwards until it stops, approximately 1/4”. Lift the door away from the

radio.

Set the battery type selector switch to ALK for non-rechargeable alkaline batteries or Ni-MH for

rechargeable Ni-MH batteries. Insert four size AA batteries, taking care to ensure that the batteries are

inserted according to the polarity diagram shown inside of the battery compartment. Replace the

battery compartment door by placing it back over the batteries and sliding it upward gently until it locks

in place.

WARNING: Never operate the PRO-18 with alkaline batteries if the Battery Type Selection switch is set

to the Ni-MH position. Intentionally or accidentally recharging non-rechargeable batteries will cause

them to overheat, leak or explode. Dispose of alkaline batteries promptly and properly. Do not burn or

bury them. Dispose of rechargeable batteries properly by taking them to an approved battery recycling

facility.
