INTRODUCTION
The PRO401 radio is a mobile radio designed for use in the Citizens Band
(CB) Radio Service. It will operate on any of the 40 AM frequencies authorized
by the Federal Communications Commission (FCC). Your radio features a
superheterodyne circuit with Phase Locked Loop techniques to assure precise
frequency control.
► Condenser microphone.
► Ceramic lter: Delivers greater selectivity and reduces adjacent channel
interference.
► AGC (Automatic Gain Control) for a constant sound level.
► Automatic modulation control for a constant audio transmit modulation
level.
► Low distortion IC audio circuit.
► Automatic noise limiter to reduce pulse noise.
► “HI-LO” switch: Adjusts output power.
► Antenna with BNC connector.
► Jack for external power source and battery charger.
► Do not expose the PRO401HH to water or extreme temperatures.
► Do not leave batteries installed over a long period of time as leakage may
occur and cause damage to the radio.
► Never use different batteries from the ones suggested.
► Never use harsh chemicals to clean this radio. Use a damp soft cloth.
