PRO-10 Scanner
(200-0170)                 Features                   Faxback Doc. # 38501


Your PATROLMAN PRO-10 scanning receiver is a completely transistorized
VHF/UHF superheterodyne receiver using dual-conversion for the VHF
band and triple conversion for the UHF band.  It is capable of
automatically scanning eight crystal controlled channels.  Some special
features are: two ceramic filters, channel lock-out circuit, skipper
circuit, AFC circuit for UHF band, scan delay circuit and AC or DC
operation.

It is designed for use in the narrow-band FM channels of public service
communications: VHF and UHF band police, fire, civil defense, radio
telephone, forestry and weather service. plus many other industrial radio
services and the 2 meter "HAM" radio band (upper end).  These and many
other services share this band of frequencies from 148 to 174 MHz and
450 to 470 MHz.

The PRO-10 features both high sensitivity and selectivity and a
sophisticated circuit which includes 10.7 MHz and 445 kHz ceramic filters
to reduce or eliminate adjacent-channel or strong-signal interference.
Such interference is often experienced when operating in urban and
metropolitan areas or where very strong and closely placed signals are
present.

An important engineering achievement, designed for practical applications,
the PRO-10 is remarkably easy to use, yet its up-to-date, complex circuit
circuit consists of 35 separate transistors (three of which are Field
Effect Transistors), five integrated circuits (which incorporate the
equivalent of hundreds of components), 34 diodes and 1 zener diode.

Guarantee:  The Radio Shack guarantee is stated on the Guarantee Card
            packed with the unit.  It is in effect from coast-to-coast.
            At any time, Radio Shack equipment can be restored to like
            new condition with original parts, with MINIMUM delay, anywhere
            in the U.S.A.-normally right in your own neighborhood.  In 98%
            of the cases, it NOT necessary to return Radio Shack
            equipment to our Laboratories.

This Receiver is designed to operate from either 120 volts AC or 12 volts
DC Negative Ground.  If it fails to operate and there is no clear reason
for the failure, first check the "power" switch (part of Volume control).
Also, before connecting the PRO-10 receiver to a DC power supply, check
the voltage polarity.  Attempting to operate the negative-ground PRO-10
from one of the rare positive-ground automotive or boat electrical
systems, or from a wrongly connected battery, will at least blow a fuse.
It may do further damage, so that expensive and time-consuming repairs are
necessary before the PRO-10 can be used again.  The Radio Shack warranty
does not apply to any damage caused by this, inadequate lightning protection, of other improper connections.
