PX777 Operation Guide The Puxing PX777 is an excellent, inexpensive handheld radio. The English language documentation provided by the manufacturer, however, has considerable room for improvement. This guide covers the basics of using the PX777 in a more understandable format. Introductory Notes When placing the radio in its charging stand, be sure that it's inserted straight and that the battery touches the charging contacts properly. It's possible to misalign the radio, which will cause it to fail to charge. You can remove the battery from the radio and charge it separately ­ not only is this useful for charging spare batteries, but it makes it easy to see how the battery should fit in the charger. 1 ­ On/Off and Volume 2 ­ Selector knob 3 ­ PTT button 4 ­ Monitor button 5 ­ Call button 6 ­ Speaker/mic jack The PX777 has a channel mode with a selfprogramming feature similar to that found on many commercial radios.
