— Highlights —

	LCD Display			Hands-free VOX
	An LCD screen allows users to view channels, call up stored information and navigate through the radio’s features.			This hands-free feature allows you to get on with other manual tasks while you stay in touch with other users.
	Monitor			Channel Alias
	This feature allows you to check if a channel is clear before you transmit.			Allows the user to give each channel a user defined name.
	Scan			Channel Step
	The channel scan feature enables a two way radio to continuously scan each channel for activity.			Channel refers to the frequency value occupied when transmitting and receiving.
	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			Key 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.			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.
	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.
	Offset			Roger Beep/Talk Confirmation Tone
	Offset is the difference between a radio channel's receive and transmit frequencies.			When this feature is activated, a tone is transmitted to the listener after a transmission.
	CTCSS/DCS			DTMF
	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.			DTMF is a technology that uses a combination of tones to perform a number of useful signaling operations.
	Keypad Tone			FM Broadcast Radio
	Pressing a single key of keypad produces a sound to remind that you already successfully press this key.			This two-way radio is also capable of receiving normal FM broadcasts.
