I changed the batteries in my outdoor RS848 temp/humidity transmitter, and now the entire unit (MRC800) has stopped working! Why?
Whenever you change the batteries you must use the reset on both the transmitter and the monitor. On the RS848, the reset is inside the battery compartment. Gently use a pencil or straightened paper clip to push the reset. On the monitor, there is a similar reset on the back above the battery compartment, or you can simply remove the monitor's batteries for a moment to reset the unit. The transmitter will blink red (trying to locate the monitor) and you should be back in business shortly!
