Battery Receiver Setup has two batteries to keep track. Here's how:

So on a hand remote, the first column is battery percentage of the hand unit. Now we have to manage the batteries in the receiver. There’s two ways to find out receiver battery percentage.

#1 By turning on the receiver, it will blink once for every ten percent of receiver battery after it succeeds in being orientated properly.

#2 Once your hand remote receives numbers, put the dial to min. then hold red. you will see a bar in the top row go from left to the right. once it says battery, you can let go the button and it will ask the receiver wirelessly its battery percentage and display it.
