— Highlights —

	Voice Prompt			Type-C Charging Interface
	The radio actually talks to you in a human-like voice. You will hear the prompt spoken in plain relative language.			The Type-C charging interface is so simple usage by specifying cables having identical plugs on both ends, which can be inserted without concern about orientation.
	1 Programming Key			Scan
	You can program or assign to perform a user specific function. Personalize the required functions for convenient and quick operation.			The channel scan feature enables a two way radio to continuously scan each channel for activity.
	Hands-free VOX			Power Adjustable
	This hands-free feature allows you to get on with other manual tasks while you stay in touch with other users.			This feature allows you to switch between high and low power modes on the radio.
	Wide/Narrow Band			Battery Saver
	Narrowband takes up less frequency space and lowers the chance for interference, wideband channels can carry more infos but require more power.			The radio will switch to automatically after being left unused for a certain amount of time, lessens the drain on your battery and makes it last longer.
	Busy Channel Lockout			Time-out Timer
	This feature keeps communication lines open by preventing radios from listening or transmitting through conversations outside their talkgroup.			This feature will stop the transmission of the two-way radio if the radio is transmitting for a long duration.
	Low Battery Alert			CTCSS/DCS
	This warning reminds that your battery is low and must be either recharged or replaced.			CTCSS uses continuous tones below 300 Hz whereas DCS uses digital data and all encoded words can be used on the same channel without interference.
