There are some variables that affect the range: where the ZvReceiver (which receives the commands from ZvRemote) is placed, the kind of walls and floors you have (stone and metal tend to reduce the range), and whether anything is stacked around the ZvReceiver. In general you should get whole-house coverage.
ZvRemote automatically adjusts its power so that it works reliably. In order to maximize the battery life, the remote will send the least amount of power that it can while still working. However, if you are out of range and the power was already automatically adjusted to maximum and the transmission is still failing, ZvRemote will blink the top LED an amber color. You can try to move the ZvReceiver to a better location or adjust the antenna for better operation.
If that doesn’t work, you can try purchasing a USB extender, which is essentially an extension cord that runs from your computer’s USB port to your peripheral device - in this case, the ZvReceiver. This allows you to move the ZvReceiver closer to your HDTV.
