— Highlights —

	Type-C Charging Interface			Dual Watch
	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.			Allows user to choose 2 priority channels to scan.
	1 Programming Key			Monitor
	You can program or assign to perform a user specific function. Personalize the required functions for convenient and quick operation.			This feature allows you to check if a channel is clear before you transmit.
	Scan			Hands-free VOX
	The channel scan feature enables a two way radio to continuously scan each channel for activity.			This hands-free feature allows you to get on with other manual tasks while you stay in touch with other users.
	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.
	Battery Saver			Busy Channel Lockout
	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 feature keeps communication lines open by preventing radios from listening or transmitting through conversations outside their talkgroup.
	Time-out Timer			Compandor
	This feature will stop the transmission of the two-way radio if the radio is transmitting for a long duration.			This feature can help improve signal-to-noise ratio, reduce the background noise and obtain good audio quality at the receiver.
	Scrambler			Frequency Hopping
	A technology is used to scramble communications to prevent other radio users in the vicinity from listening to your conversations.			Frequency hopping is a method of transmitting radio signals by rapidly switching the carrier between different frequency channels.
	Digital Anti Cracking			Voice Prompt
	Using the digital anti-cracking feature, you can realize the anti-cracking function and avoid receiving illegal signals.			The radio actually talks to you in a human-like voice. You will hear the prompt spoken in plain relative language.
	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.
	Battery Capacity Check Alert			Emergency Alert
	This function is to query the current battery power based on the sound.			If an operator needs to send an immediate and urgent request for help, the push of just one button can trigger a call for assistance.
	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.
