match the (+) and (-) symbols on the batteries with the (+) and
(-) symbols inside the battery compartment.

Precautionary Tips for Inserting the Batteries:
Do not mix new and old batteries. This may result in cracking or leakage that may cause a fire or
lead to personal injury.
Inserting the batteries incorrectly may also result in cracking or leakage that may cause a fire or
lead to personal injury.
Dispose of batteries according to local hazardous waste regulations.
Keep the batteries away from children and pets.
Remote Control Range
Point the remote control directly at this sensor for the best
response to the remote signal.
Do not place any obstacles between the remote control and
the remote control sensor.
The effective range of the remote control is approximately
22 feet (7 meters) from the front of the remote control sensor,
30° to the left and right, 20° up and down.
VIZIO Remote Control Precautions
The remote control should be kept dry and away from heat sources. Avoid humidity.
If the TV responds erratically to the remote control or does not respond at all, check the batteries.
If the batteries are low or exhausted, replace them with fresh batteries.
When not using the remote control for a long period of time, remove the batteries.
Do not take the batteries apart, heat them, or throw them into a fire.
Do not subject the remote control to undue physical stress, such as striking or dropping it.
Do not attempt to clean the remote control with a volatile solvent. Wipe it with a clean, damp
cloth.
