ON Indicator
An ON Indicator light illuminates after any active button on the remote is pressed. This indicates that the remote is functioning correctly and transmitting an infrared (IR) signal to your device.
Specific Functions
While this remote provides most original commands, some specific functions such as page flip, keystone correction, video adjustment, and certain number pad functions may not work with all devices. The remote does not include a laser pointer function.
Maintenance
Cleaning
To clean the remote control, use a soft, dry cloth. Avoid using liquid cleaners or abrasive materials, as these can damage the remote's surface or internal components.
Battery Replacement
Replace batteries when the remote's response becomes inconsistent or the ON Indicator light dims. Always replace both batteries simultaneously with new AAA batteries. Do not mix old and new batteries or different types of batteries.
Durability
The remote is constructed from durable plastic designed to withstand regular use. The buttons are designed to be comfortable and responsive without being overly sensitive, which helps prevent accidental signals and extends their lifespan.
