A22 Mini Light Weight Walkie Talkie

The A22 is lightweight, compact, and easy to use. Only 25g and it can be easily carried on a collar or in a pocket and is paired with the most popular Type-C charging port making this an easy solution to your productivity problems.

— Highlights —

	Mini Size			Voice Prompt
	Only 25g Mini Pocket Size with lightweight design and easy to use are good for your communication privacy with clear voice			The radio actually talks to you in a human-like voice. You will hear the prompt spoken in plain relative language.
	Intelligent Power Saver			Low Battery Indicator
	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 circuit alerts the user when the battery needs changing or charging.
	Low Battery Alert			Power-on Tone
	When the battery voltage is low, it will prompt "Please change the battery" and the red light will flash at the same time. Please charge right now.			A sound prompt when you turn on the power, which is a very practical function in dark places or for people with visual impairments.
	CTCSS/DCS			Wide/Narrow Band
	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.			Narrowband takes up less frequency space and lowers the chance for interference, wideband channels can carry more infos but require more power.
	Frequency Hopping			Easy Pairing
	Frequency hopping is a method of transmitting radio signals by rapidly switching the carrier between different frequency channels.			This radio has a fast frequency measurement and decoding function, easy to talk with other radios.
	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.
	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.
	Type-C Charging Interface
	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.
