Speak into the microphone when transmitting. - Wrist Strap Slot
Connect the wrist strap to the belt clip. - Speaker Jack
Connects to an external speaker (not included). The internal speaker is disabled. - Microphone Jack
Connects to an external microphone (not included). - 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.
- 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
- Plug the DC power cable into the PRO401HH.
- Plug the other end into your vehicle’s cigarette lighter/DC power conversion plug.
- 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.
- Open battery cover.
- Set the internal switch to match the battery type you are using [either alkaline or rechargeable (Ni-MH) batteries].
- Insert the 9 batteries according to the directions indicated inside the battery compartment.
- 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.
