If you're trying to change the channel, it's the last 2 buttons on the side of the tv.
If you're trying to scan for additional channels you'll need a universal remote.
based on what the manual says you need to press the "menu" key to do a manual channel search. unfortunately there is no menu key on the side of the tv.
here is a cheap universal remote that includes the menu button. https://www.amazon.com/RCA-RCR503BZ-3-Device-Palm-Sized-Universal/dp/B007TAMHRI/
