— Highlights —

	Screen Display			1 Programming Key
	An LCD screen allows users to view channels, call up stored information and navigate through the radio’s features.			You can program or assign to perform a user specific function. Personalize the required functions for convenient and quick operation.
	Type-C Charging Interface			Signal Strength Indicator
	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 Signal Strength Indicator measures the amount of power present in a radio signal. It is an approximate value for signal strength received on an antenna.
	Voice Prompt			Hands-free VOX
	The radio actually talks to you in a human-like voice. You will hear the prompt spoken in plain relative language.			This hands-free feature allows you to get on with other manual tasks while you stay in touch with other users.
	Monitor			Scan
	This feature allows you to check if a channel is clear before you transmit.			The channel scan feature enables a two way radio to continuously scan each channel for activity.
	Power Adjustable			Wide/Narrow Band
	This feature allows you to switch between high and low power modes on the radio.			Narrowband takes up less frequency space and lowers the chance for interference, wideband channels can carry more infos but require more power.
	Key Lockout			Battery Saver
	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.			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.
	Time-out Timer			Busy Channel Lockout
	This feature will stop the transmission of the two-way radio if the radio is transmitting for a long duration.			This feature keeps communication lines open by preventing radios from listening or transmitting through conversations outside their talkgroup.
	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.
	Time & Date			Keypad Tone
	It displays the current date and time on radio.			Pressing a single key of keypad produces a sound to remind that you already successfully press this key.
	Power-on Tone			Low Battery Alert
	A sound prompt when you turn on the power, which is a very practical function in dark places or for people with visual impairments.			This warning reminds that your battery is low and must be either recharged or replaced.
	CTCSS/DCS
	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.
