To power your scanner from a 12V power source in your vehicle, such as
cigarette-lighter socket, you need a 12V, at least 600mA DC with 7.75mm
outer/1.7mm inner plug cigarette-lighter adaptor (not supplied).
Insert the adaptor’s barrel plug into the scanner’s DC 13.8V jack.
Plug the adaptor’s other end into your vehicle’s cigarette lighter or power
socket.
Warning: You must use a power source that supplies 12-14.4 VDC and is
rated for 600mA. Its center tip must be set to positive and its plug must fit
the scanner’s DC 13.8V jack. The supplied DC power adaptor meets these
specifications. Using a DC adaptor that does not meet these specifications
could damage the scanner or the adaptor.
Warning: The DC power cord is equipped with an inline fuse. This fuse
protects your scanner and your vehicle from damage in case of equipment
malfunction or a short circuit. Do not remove the inline fuse holder from the
DC power cord. If the fuse blows, replace it with a 2A fuse and apply power
again. If the fuse blows again, check all wiring for short circuits, and check
the radio for a malfunction.
Note: When your radio is connected to your vehicle’s DC power system,
you may hear noise from your vehicle’s electrical system in the radio’s
speaker. Consult with a local electronics supply store to obtain a filter that
will reduce or eliminate this noise.
Connecting an earphone or headphones
For private listening, you can plug an 1/8” (3.5mm) mini-plug earphone or
headphones (not supplied), into the headphone jack on the from panel.
This automatically disconnects the internal speaker.
Connecting an Extension Speaker
In a noisy areas, or you install the scanner into your dashboard, extension
speaker (not supplied) might provide more comfortable listening. Plug the
speaker cable’s 1/8 inch (3.5mm) mini-plug into your scanner’s EXT-SP
jack, located on the rear panel of the radio.
