CAVS Remote Controller
How to prevent battery draining in the CAVS PC remote controllers (for JB-199 mini, JB-199 mini pro)
CAVS Remote Controller (for JB-199 mini and JB-199 mini pro) is a Wi-Fi 2.4 Ghz device that has a dual function of being a wireless mouse for the CAVS karaoke players. It means that the remote controller can be communicating with the karaoke player although no button is actually being pressed. This can lead to battery draining faster than expected.
To turn off the wireless mouse feature, press the red cursor button located below the circular button at the center. Confirm that a physical movement of the remote controller does not move the screen cursor of the karaoke player. Note that the turning off the cursor will not interfere with the normal use of the remote controller for selecting and playing songs.
To turn on the wireless mouse feature, press the red cursor button again.
