Desktop Operation
The mounting bracket works as a desktop stand when
attached underneath the radio. Use the provided
rubber feet to prevent sliding or scratching. Do not
use the rubber feet if mounting permanently to a fixed
surface. Extra pads are provided for additional stability.
1. Attach the adhesive rubber feet to the
mounting bracket.
2. Attach the two adhesive rubber washers over
the mounting holes, between the mounting
bracket sides and the scanner’s side holes.
3. Position the bracket with the two recessed fee
toward the front of the scanner.
4. Use the two provided knobs to secure the
scanner within the mounting bracket.
Mount Installation
Attach the bracket over the radio to suspend the
scanner from above. Attach the bracket underneath
the scanner to mount it on top of a flat surface.
Your PRO-652 also fits into the included DIN-E
compatible sleeve for existing dashboard openings.
NOTE: In some cases, installation requires
specialized tools and skills. If in doubt, seek
assistance from a local car audio electronics
installation shop, or a local two-way radio dealer.
Select a location that does not interfere with driving
or with the deployment of your vehicle’s air bags.
Do not mount this or any other equipment where
deployment of the air bags might cause it to be
propelled towards passengers. If necessary, seek
advice from your automotive dealer or service shop.
Use the mounting bracket as a template to mark the
locations for the two mounting screws.
Drill holes that are slightly smaller than the screws.
Use caution not to damage wiring or components
that are located behind the mounting surface.
Using the provided screws and lock washers, attach
the mounting bracket to your vehicle.
Headphones and Speakers
You can plug headphones (not supplied) or an
amplified speaker (not supplied) with a
1/8-inch (3.5 mm) mini-plug earphone or in the
headphone jack on top of your scanner. This
automatically disconnects the internal speaker.
NOTE: Use an amplified speaker with this scanner;
Non-amplified speakers do not provide sufficient
volume for comfortable listening.
Listening Safely
To protect your hearing, follow these guidelines
when you use 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 after 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.
Wearing headphones while operating a motor
vehicle can create a traffic hazard and is illegal in
most areas. Even though some headphones let you
hear some outside sounds when listening at normal
volume levels, they still can present a traffic hazard.
Exercise extreme caution!
