Yaesu FT-70DR Cheatsheet

Belt Clip

Yaesu sells handheld transceivers with an optional belt clip, detached by default. To attach the clip, remove any battery. Then firmly insert the two belt clip screws with an appropriate screwdriver. My radio came with two small Phillips head screws.

Charging

The battery charges via a barrel plug located on the right side of the radio.
