Hydra HD – A Series User's Guide
The Hydra HD remote controls can also be used to control TVs and other A/V devices such as DVD players
and recorders. The remote controls use infrared (IR) light signals to control other devices that the remote is
programmed to control. IR signals travel only short distances (40 feet or less), and cannot go through walls
or other solid objects. You must point the remote control directly at these devices, with no objects blocking
the line of sight.

For details of how to program the Hydra remote controls and the supported devices, please refer to the
Hydra HD Quick Reference Guide, Universal Remote Control User Guide or the URC PLUS User's Guide.
