The correct way to use IR remote control: Batteries must be installed before use. 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:
Ÿ Check the battery polarities.
Ÿ Check whether the battery power.
Ÿ Check whether the remote sensor is obscured.
Ÿ Check whether a fluorescent lamp is being used nearby.
If the remote still can’t function normally beyond the above situations, please change a remote and try again,
or contact the device provider.
