777 Pro has many high-tech features to ensure optimal communication during the night-life hours. First of all, 777 Pro has an EDDTM screen with white lighting, to display the channels well in the dark. In noisy contexts the Vibracall function allows you to hear notifications and the extra powerful speaker allows you to receive communications.Another very important element of the 777 Pro radio is its autonomy: up to 14 hours thanks to the 1000mAh lithium battery. And if it needs to be recharged fast? Just use a USB cable and plug it into the appropriate side socket, or use the desktop.
