IC-F11 / F21 Series
No problem. I'm going to need you to remove the battery of your handheld.

Look for the sticker located on the back casing of the handheld unit. Be sure you are looking at the model or part number on the radio itself, not the battery.

Find where it says model or part number and type that into the box below. If you have problems finding this and need help, feel free to give us a call at 1-888-742-5893.
