— Highlights —

	Dual Band			Dual Display
	Radios with Dual Band capability can transmit and receive on both UHF and VHF radio bands.			The LCD screen allows users to view the current information of the two frequency bands or other settings, providing a larger amount of visual information.
	Dual Watch			Dual Receive
	Allows user to choose 2 priority channels to scan.			Like having two radios in one, the dual receive function allows you to receive and listen to two different channels simultaneously .
	Screen 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.
	Signal Strength Indicator			Channel Alias
	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.			Allows the user to give each channel a user defined name.
	Channel Step			Power Adjustable
	Channel refers to the frequency value occupied when transmitting and receiving.			This feature allows you to switch between high and low power modes on the radio(25W/10W/4W).
	Monitor			Hands-Free VOX
	This feature allows you to check if a channel is clear before you transmit.			This hands-free feature allows you to get on with other manual tasks while you stay in touch with other users.
	Scan			Priority Scanning
	The channel scan feature enables a two way radio to continuously scan each channel for activity.			During the scanning process, the set priority channel is scanned first.
	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.
	Busy Channel Lockout			Auto Power Off
	This feature keeps communication lines open by preventing radios from listening or transmitting through conversations outside their talkgroup.			In order to extend the life of the battery, when activated, these radios will automatically turn off when they are inactive for a period of time.
	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			Offset
	A technology is used to scramble communications to prevent other radio users in the vicinity from listening to your conversations.			Offset is the difference between a radio channel's receive and transmit frequencies.
	Noise Reduction			Keypad Tone
	Noise reduction is the process of removing noise from a signal, in order to improve background sound quality to be clearer.			Pressing a single key of keypad produces a sound to remind that you already successfully press this key.
	Roger Beep/Talk Confirmation Tone			1750Hz
	When this feature is activated, a tone is transmitted to the listener after a transmission.			1750Hz is used to connect to the repeater.
	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.
