INTRODUCTION

The PRO401HH 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.

FEATURES

• 40 AM channels
• Condenser microphone.
• Ceramic filter: 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.
• TX Power select slide switch (HI = 4W; LOW = 1W)
• Antenna with BNC connector.
• External speaker jack and external MIC jack
• Jack for external power source and battery charger.
• Rechargeable (9 AA Ni-MH) or Alkaline (9 AA) batteries
• Internal battery select switch (alkaline or rechargeable)

SAFETY NOTICE

• 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.

4. Push to Talk
   Allows you to transmit.

5. Antenna Jack
   Connect the detachable antenna to this jack.

6. Squelch knob
   Adjusts the level at which the radio squelches or suppresses weak radio signals. To filter out weaker signals and background noise, turn the knob clockwise to increase the squelch level. To decrease the squelch level so you can hear weaker radio signals, turn the knob counter-clockwise.

7. Volume Control
   Powers on the radio and adjusts the volume.

8. Microphone
   Speak into the microphone when transmitting.

9. Wrist Strap Slot

10. Speaker Jack
    Connects to an external speaker (not includerd). The internal speaker is disabled.

11. Microphone Jack
    Connects to an external microphone (not included).

12. 13.8 V DC External Power Jack
    Provides power to the unit. you can use external power sources such as a car battery to power the unit and to recharge the Ni-MH rechargeable batteries.

13. Transmit Power Switch (HI/LOW)
    Select a power output level for transmission.

NOTE: FCC rules reserve Channel 9 for motorist assistance and other emergency communications. Channel 9 should only be used in situations where there is immediate danger to the safety of individuals or the protection of property. Make sure you have read and understood part 95 of the FCC rules and regulations before using the transmitter.

SET UP

INSTALL ANTENNA
Install the included rubber antenna onto the radio. The PRO401HH can also use any type of 50 Ω / 27 MHz band antenna. Although a telescoping antenna might provide better transmission and receiving, it is not as compact or easy to use as the antenna included in the package.

CONNECTING TO POWER
Your PRO401HH can operate on DC power or batteries.

DC Power

1. Plug DC power cable into the PRO401HH.
2. Plug the other end into your vehicle’s cigarette lighter/DC power conversion plug.
3. The red power LED is steady on when the unit is connected to external power (not batteries).

Battery Power
You can use either 9 non-rechargeable alkaline batteries or 9 rechargeable Ni- MH batteries with this unit.

1. Open battery cover.
2. Set the internal switch to match the battery type you are using [either alkaline or rechargeable (Ni-MH) batteries].
3. Insert the 9 batteries according to the directions indicated inside the battery compartment.
4. Close battery cover.

LED Display
The LED display turns off after 1.5 seconds to conserve battery power. It will also turn off 1.5 seconds after you close Squelch. To see the display again, open Squelch.

Low Power Indication
The red LED blinks when battery power is low. Replace/recharge the batteries or connect to a power source.
