SPECIAL NOTE FOR XFINITY 4K USERS AT BOTTOM OF ARTICLE
The Xfinity remote uses either RF (radio frequency) or IR (infrared) signals to control the Xfinity box. Caavo can only send IR. IR signals are digitally-coded pulses of infrared radiation to control functions such as power, volume, and channel changes. These signals require a direct "line of sight" to work properly. If the "line of sight" from the Caavo box is changed/blocked, you may need to either move the Xfinity box to a better location or try using one of the Caavo IR accessories (either the 9ft IR cable or the HDMI-IR cable with the 3ft IR cable). If you are already using these, keep in mind that if the transmitter is moved out of alignment that IR control can become sporadic or stop working altogether.
If the device, or Caavo, is behind a closed cabinet door you will need to point an IR transmitter at the device in order to send a signal.
Things to check:
- Make sure Caavo has a line-of-sight to the Xfinity device. If you are using an IR transmitter, check its connection to Caavo's IR port
- Check that the transmitter wasn't knocked out of alignment. The transmitter should point at the sensor of the device you intend to control, not at Caavo.
- If you are using the Caavo HDMI-IR cable, make sure the HDMI-IR cable is connected directly to the Xfinity device (not to Caavo) and that the transmitter is plugged in firmly to the HDMI-IR cable
- Try restarting the Xfinity device and Caavo
IR can be difficult to troubleshoot because it cannot be seen with the naked eye. Try using a digital camera (your phone's camera should work) to "see" the Infrared signal blasting from the Caavo box as well as any attached emitters. The Caavo box has two emitters on the front and one on each side that will light up when issuing IR commands like Volume UP/Down. This is also a good method to determine if your IR transmitter is actually sending a signal or not.
For Xfinity 4K users, the IR receiver is extremely directional and you must make sure to place the Caavo IR blaster right in front to get consistent control.
