How do I charge the walkie talkie with a Micro-USB charger?

Turn off the radio, plug the micro-USB cable into the charging port on your radio, and connect the other end to a wall power outlet using a certified 5V adapter (≥1A). The battery meter will move to indicate charging is in progress. It is recommended to remove the radio from the charger within 16 hours and power it off while charging. Note: Only use the Micro-USB charger with nickel metal hydride (NiMH) rechargeable batteries, not alkaline batteries.
