— Highlights —

	Type-C Charging Interface			Voice Prompt
	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.			The radio actually talks to you in a human-like voice. You will hear the prompt spoken in plain relative language.
	2 Programming Keys			Hands-free VOX
	You can program or assign to perform a user specific function. Personalize the required functions for convenient and quick operation.			This hands-free feature allows you to get on with other manual tasks while you stay in touch with other users.
	Scan			Power Adjustable
	The channel scan feature enables a two way radio to continuously scan each channel for activity.			This feature allows you to switch between high and low power modes on the radio.
	Compandor			Scrambler
	This feature can help improve signal-to-noise ratio, reduce the background noise and obtain good audio quality at the receiver.			A technology is used to scramble communications to prevent other radio users in the vicinity from listening to your conversations.
	Wide/Narrow Band			Power-on Tone
	Narrowband takes up less frequency space and lowers the chance for interference, wideband channels can carry more infos but require more power.			A sound prompt when you turn on the power, which is a very practical function in dark places or for people with visual impairments.
	Battery Saver			Low Battery Alert
	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.			This warning reminds that your battery is low and must be either recharged or replaced.
	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.
	CTCSS/DCS			Frequency Hopping
	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.			Frequency hopping is a method of transmitting radio signals by rapidly switching the carrier between different frequency channels.
	Key Lockout			Keypad Tone
	When activated this feature allows the user to lock the buttons so that in case the user presses them by mistake, it does not result in some unwanted action.			Pressing a single key of keypad produces a sound to remind that you already successfully press this key.
