The correct way to use IR remote control: Batteries must be installed before operation. Please aim the remote
control at the IR receiver on the GVR3550 then make operations. If the GVR3550 receives the control’s
command, you can use the control to manipulate the GVR3550. If failed, please check whether the following
reasons are the causes:
Check the polarities of batteries
Check whether the batteries are used up
Check whether the remote sensor is obscured
