Congratulations on your purchase of the Uniden
TR620 radio. This product is a lightweight, 
palm-sized radio. Use it at sporting events to stay 
in contact with family and friends, hiking, skiing, 
outdoors, or in a neighborhood watch for vital 
communication.

Your package contains the TR620 radio, this 
reference guide and a belt clip. You will need to 
purchase 3 AAA alkaline batteries in order to 
operate the unit.

Your TR620 radio uses 3 AAA alkaline batteries 
for power. We recommend using high quality 
alkaline batteries.

To install the batteries:

1) Make sure your radio is OFF.
2) Remove the battery compartment door by 

pressing on and sliding the compartment door,
allowing the door to be removed.

3) Install 3 AAA 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) Replace the battery compartment door by sliding

the door into place.

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

1) Press and hold the 

key to turn the radio ON.

2) To change the volume level press the

▲ or ▼ keys to increase or

decrease the volume level.

3) Press and hold the 

key to turn the radio OFF.

Your radio emits a beep each time one of the keys
(except for the PTT button and call key) is pressed.
The sound of the Key Beep will increase or
decrease depending on the volume level setting.

To turn OFF this beep:

Press and hold the call key while turning ON the radio.

To turn ON this beep:

Turn the radio OFF and ON again.

Your TR620 radio has 22 channels you can use to
talk to others. In order to speak to someone, each
of you must be set to the same channel.

To choose a channel:

Press the channel/scan

▲ or ▼ keys to increase

or decrease the channel number displayed.

Your TR620 radio has a channel Scan feature that
allows you to easily Scan all 22 channels. When an
active channel is detected, the unit will pause on
that channel until the channel is clear. Then after 
a 2 second delay, the unit will continue scanning.
Pressing PTT button 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 channel/scan
▲ or ▼ key. The channel number on the display
will rapidly cycle through the channels.

To turn OFF channel scanning:

Press either the channel/scan

▲ or ▼ key.

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.

While you are transmitting the tx icon is 
displayed. 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. You can now receive incoming calls.
While receiving, the rx icon is displayed.

Your TR620 radio is equipped with a call tone that
will be transmitted when the call key is pressed.

To transmit the call alert tone, press the call key.
The tone will automatically be transmitted for a fixed
length of time.

The TR620 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.

Your TR620 radio allows you to listen in for weak 
signals on the current channel at the press of a key.

To turn ON monitor mode:

Press and hold the volume/mon

▲ or ▼ key.

The rx icon will blink.

To turn OFF monitor mode:

Press the volume/mon

▲ or ▼ key. The rx icon

will disappear.

Your TR620 has a unique circuit designed to 
dramatically extend the life of the batteries.
If there is no transmission nor an incoming call within 
2 seconds, your radio switches to the Power Save mode.
The radio is still able to receive transmissions in this mode.

 

Note: If you press either the channel/scan

▲

or 

▼ key while the unit is pausing on a 

channel, scanning will resume.
