— Highlights —

	LCD 1.44-inch Display			Type-C Charging Interface
	An LCD screen allows users to view channels, call up stored information and navigate through the radio’s features.			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.
	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.
	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			Key Lockout
	Narrowband takes up less frequency space and lowers the chance for interference, wideband channels can carry more infos but require more power.			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.
	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.
	Private Call/Group Call/All Call			Voice Prompt
	Private Call allows a radio user to place a call to just one user, Group Call provides voice call service in a group.			The radio actually talks to you in a human-like voice. You will hear the prompt spoken in plain relative language.
	Low Battery Alert			Keypad Tone
	This warning reminds that your battery is low and must be either recharged or replaced.			Pressing a single key of keypad produces a sound to remind that you already successfully press this key.
	Roger Beep/Talk Confirmation Tone			Call Tone
	When this feature is activated, a tone is transmitted to the listener after a transmission.			Call tones allow you to transmit a tone to other radios in your group to alert them that you want to talk.
	Silent Mode			CTCSS/DCS
	In silent mode, the radio will indicate an incoming transmission without making an audible alert of any kind.			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.
