Specific Functions:
While this remote provides most original commands, some specific functions such as page flip, keystone correction, video adjustment, or certain numerical inputs may not work properly with all devices. This is due to variations in original equipment manufacturer (OEM) remote codes and is not a defect of the Tekswamp remote.
Maintenance
Cleaning:
To clean the remote control, use a soft, dry cloth. Do not use liquid cleaners, abrasive pads, or chemical solvents, as these can damage the remote's surface or internal components.
Battery Replacement:
Replace batteries when the remote's response becomes sluggish or the indicator light fails to illuminate consistently. Always replace both batteries at the same time with new AAA batteries. Do not mix old and new batteries or different types of batteries.
Storage:
Store the remote control in a cool, dry place away from direct sunlight and extreme temperatures. If the remote will not be used for an extended period, it is recommended to remove the batteries to prevent leakage.
