PRO-27
(200-0108) Features Faxback Doc. # 39653
Your PRO-27 is a compact monitor/receiver that makes it easy to follow
the action wherever you go. It picks up any two frequencies you select
in the VHF HI (144-174 MHz) band or the UHF (450-512 MHz) band. Public
service communications, police, fire, civil defense, the 2-meter ham
radio bands (144 - 148 MHz), and many other services share these bands.
Radio Shack's "Police Call Directory including Fire & Emergency Services"
is an excellent reference for finding specific frequencies in different
locales.
Obtain the correct crystals for the frequencies that interest you and
plug the crystals in. Your local Radio Shack has crystals on hand, or
can special-order them for you. (See "Specifications," Faxback Doc. #
39657.)
For your own protection, record the serial number of this unit in the
space provided. You'll find the serial number in the battery compartment.
Your receiver operates between 144 to 174 MHz and from 450 to 512 MHz.
For the best sensitivity on the VHF Hi band, stay within +/4 MHz of 153
MHz (149.157 MHz) and UHF, +/15 MHz of 465 MHz (450-480 MHz). The
reception can be moved up or down in either band of frequencies by
special realignment of the front-end circuitry of this receiver. This
realignment should be attempted only by qualified electronic service
technicians who have adequately calibrated, precision test equipment.
