As I’m sure you already know, your receiver’s batteries last 20 hours. If you use your receiver for 5-10 minutes at a time, you will easily get 20 hours, possibly more. It is recommended to turn your receiver on for your entire show, and then turn it off afterwards. This is the most effective way to use your receiver.
When your batteries do get low, you will begin to get fewer buzzes than you are supposed to. For example, if the number on your I/0 is 5, you may only get 3 buzzes. The batteries are programmed to pulse the motor, and when it does so, it consumes a lot of power. This causes the battery voltage to go down, which can cause it to reset. The reset signal is one long buzz.
Lithium batteries recharge themselves when in the off position. This may cause your receiver to begin to work again for a short period of time. But, it will not last long, and it will not be reliable. So if you begin to receive long buzzes or abnormal buzzes, please change your batteries. You can purchase these CR2032 lithium batteries at a local electronics store. We recommend using Duracell, Energizer, Panasonic, or Sony battery. RadioShack batteries do not work well in this application.
If you have changed your batteries and you are still getting long buzzes, you will want to check your battery clasps. Please watch the video to learn how to check your battery clasps.
