— Highlights —

	LCD 1.77-inch Display			Dual PTT
	An LCD screen allows users to view channels, call up stored information and navigate through the radio’s features.			You can monitor two channels at one time. If you have two groups of people you contact regularly this can be a very useful feature.
	Dual Display			Dual Receive
	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.			Like having two radios in one, the dual receive function allows you to receive and listen to two different channels simultaneously .
	Dual Watch			1 Programming Key
	Allows user to choose 2 priority channels to scan.			You can program or assign to perform a user specific function. Personalize the required functions for convenient and quick operation.
	Channel Alias			Monitor
	Allows the user to give each channel a user defined name.			This feature allows you to check if a channel is clear before you transmit.
	Channel Step			Scan
	Channel refers to the frequency value occupied when transmitting and receiving.			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.
	Scrambler			Voice Prompt
	A technology is used to scramble communications to prevent other radio users in the vicinity from listening to your conversations.			The radio actually talks to you in a human-like voice. You will hear the prompt spoken in plain relative language.
	Emergency Alert			Remote Alert
	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.			With remote alert your radio can be programmed to automatically transmit a background sound.
	Keypad Tone			Roger Beep/Talk Confirmation Tone
	Pressing a single key of keypad produces a sound to remind that you already successfully press this key.			When this feature is activated, a tone is transmitted to the listener after a transmission.
	NOAA Weather Alerts			CTCSS/DCS
	This feature will give you the latest NOAA weather information delivered to your radio real-time.			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			2-Tone
	DTMF is a technology that uses a combination of tones to perform a number of useful signaling operations.			This feature employs a sequential transmission of 2 audible tones, enabling the receiver to hear an alert tone.
	5-Tone
	Similar to 2-tone, the 5-Tone is used to enable alerts, alarms, send IDs, and many other functions.
