Replacement for Onkyo RC-421S, CR305TX, CR305X.
This universal remote control is a direct replacement for the original Onkyo RC-421S, CR305TX, CR305X, CS209, and CS210 models. It replicates every button and function of the supplied factory remote. The unit arrives pre-programmed and ready for immediate use once batteries are inserted. It suits owners who have lost or damaged their original handset.
Single-device infrared control
The remote supports control of one device using infrared wireless technology. It requires a clear line of sight to the Onkyo component for reliable operation. This specification means it cannot consolidate other home-theatre equipment such as televisions or streaming boxes. Buyers needing multi-device control should look elsewhere.
Powered by AAA batteries
Two AAA batteries are required to operate the handset; they are not included in the package. The infrared emitter keeps power draw low, so battery changes are infrequent. No pairing, Wi-Fi setup, or software updates are involved — just insert cells and point at the receiver. The 12-month guarantee covers defects in materials and workmanship.

Questions about this item
What does the single-device support mean when I use this remote?
The remote controls one Onkyo component at a time and replicates every button from the original RC-421S, CR305TX, CR305X, CS209 or CS210 handset.
How does the infrared link limit where I can point the remote?
Infrared requires a direct line of sight to the receiver on the Onkyo unit; obstacles or extreme angles will block the signal.
