Multiple 2-Tone, Multiple 5-Tone
Multiple 2-Tone, Multiple 5-Tone Up to 10 2-Tone and eight 5-Tone codes can be decoded on a channel. When a matched tone is received, the following items are programmable for each code.

• Beep sound
• Answer back
• Scan
• Bell icon
• Radio stun/kill/revive

Radio Kill, Stun and Revive
The radio kill/stun functions disable a lost or stolen radio over the air, eliminating security threats from undesired listeners. When the stun command is received, all functions will be temporarily locked out until the revive command is received or the unlock password is entered.

Lone Worker Function
When the radio is not operated for a present period, the radio sounds a beep and requires you to push any button. If the radio is still not operated for a specified wait period, an emergency signal automatically transmits and informs co-workers that something may have happened to the individual worker.

Mode Dependent Scan
In the mode dependent setting, the scanning setting is dependent on the operating channel. When you change the operating channel the scanning list automatically changes the list set for that channel. It is convenient when you move to a different operating area and change operating channel, you don't have to change the scanning setting.

Tx Channel Setting and Talk Back Function
The Tx channel setting allows you to program a transmission channel while scanning. Start channel, last detected channel, priority and preprogrammed channels are selectable. Prior to the Tx channel setting, the talk back function allows you to talk on the last detected channel, while scanning resumes after a preset time. The user can easily make a quick response with this function.

Optional Unit
The 5021 Series has a 40–pin option slot for adding an optional unit. Optional voice scrambler units, UT-109R or UT-110R provide secure private conversation. Optional DTMF decoder unit, UT-108R offers DTMF decode capability.
