INSTALL THE BATTERY
Your FRS420 radio uses 3 AA Alkaline batteries for power. I RECOMMEND USING NI METAL HYDRIDE RECHARGEABLE BATTERIES.

To install the batteries:

1) Make sure your radio is off.

2) Remove the battery compartment door by sliding it down from the unit.

3) Install 3 AA Alkaline batteries (not included) into the battery compartment. Be certain to follow the + and - symbols in the compartment. Installing the batteries incorrectly will prevent the unit from operating.

4) Optional: Your FRS420 radio can be powered using an optional NiMH battery pack specifically designed for this model. Remove the alkaline batteries and install the battery pack by inserting into the battery compartment. Follow the instructions found with the NiMH accessory. YOU CAN ALSO USE 3 STANDARD NiMH BATTERIES.

5) Replace the battery compartment door by pushing it up until it is secure. When the batteries in the unit are low, the unit will emit a low battery tone indication. Replace the batteries immediately to continue using the radio.

In order to get the most out of your new radio, read this reference guide completely before attempting to operate the unit.

Turning the Radio On and Adjusting the Volume

1) Rotate the on/off/volume control clockwise to turn the unit on and increase the speaker volume

2) Rotate the on/off/volume control counterclockwise to decrease the speaker volume and turn the unit off.

Your radio emits a beep each time one of the buttons is pressed. To turn this sound off, press call/menu while turning on the radio. To turn this sound on, press call/menu while turning on the radio again.

Your radio has 14 channels and 38 CTCSS codes you can use to talk to others. In order to speak to someone, each of you must be set to the same channel and CTCSS code.

To choose a channel: Press the s or t button to increment or decrement the channel number displayed.

To access the advanced features of the FRS420, your radio has a menu function.

1) To enter the menu, press and hold the call/menu button for 1 second until the CTCSS code flashes.

2) Additional presses of the call/menu button will advance through the menu until exiting to "normal" operating mode.

3)Other methods of exiting the menu function are:

a. Press and hold the call/menu button for 1 second again.

b. Press PTT.

c. Wait 10 seconds until the unit automatically returns to "normal" mode.

Choosing a CTCSS Code

Each of the FRS channels 1-14 may have any one of the codes 0-38 selected. Code "0" indicates no CTCSS code selected and your radio can receive a signal regardless of the code settings of the transmitting radio.

1) Enter the menu. The CTCSS code on the LCD display will flash.

2) Press the s or t button to increment or decrement the code number displayed.

3) Exit the Menu to return to "normal" mode.

Talking on Your Radio

To talk to others using the radio: 

1) Press and hold the PTT button and speak in a clear, normal voice about 2-3 inches away from the microphone. To avoid cutting off the first part of your transmission, pause slightly after pressing the PTT button before you start talking.

2) When you are finished speaking, release the PTT button. Press the call/menu button to send an alert tone to others in your party. The tone will automatically be transmitted for a fixed length of time.

Your FRS420 radio is equipped with 5 selectable call tones that will be transmitted when the call/menu button is momentarily pressed.

To select a call tone:

1) Enter the Menu and then press the call/menu button once. The letters CA will show on the display along ,with the current call tone number (1-5).

2) Press the s or t button to increment or decrement the number to the desired call tone. Each tone will be heard through the speaker.

3) Exit the Menu.

To transmit the selected call alert tone, momentarily press the call/menu but-ton. The selected tone will automatically be transmitted for a fixed length of time.

Note: Do not hold the call/menu but-ton down as this will cause the unit to enter the Menu mode.

Your FRS420 radio is equipped with a vibrator that can be used for notification of an incoming call alert from other Uniden radios equipped with the same feature.

To select the vibrate alert:

1) Enter the Menu and then press the call/menu button twice. The VIBRATE icon on the LCD display will be shown .along with on or off indicating the vibrate alert feature status.

2) Press either the SCAN UP OR SCAN DOWN button to toggle the feature on or off.

3) Exit the Menu.

Your FRS420 radio has a channel scan feature that allows you to easily scan all 14 channels. When an active channel is detected, the unit will pause on that channel until the channel is clear. Then after a 4 second delay, the unit will continue scanning. Pressing PTT while the scan is paused on a channel will allow you to transmit on that channel.

To turn on channel scanning:

Press and hold either the s or t button until the SCAN icon on the display is shown. The channel number on the display will rapidly cycle through the channels.

To turn off channel scanning:

Press any key to cancel SCAN mode.

The LCD backlight will automatically turn on with any key press. The LCD display will illuminate for 5 seconds before turning off.

The FRS420 radio is equipped with an automatic squelch system which shuts off weak transmissions and unwanted noise due to terrain conditions or if you have reached your range limit.

To temporarily disable the Auto Squelch and listen to the selected channel, rapidly press the PTT button twice. The channel will remain open until the PTT button is pressed. THIS IS IMPORTANT FOR RECEIVING VERY WEAK SIGNALS.

To re-engage the Auto Squelch, repeat the double PTT key press.

Your radio has a unique circuit designed to dramatically extend the life of the batteries.

If there is no transmission within 5 seconds, your radio switches to the Power Save mode. The radio is still able to receive transmissions in this mode.
