What is the transmission range of the receiver and motion sensor?

The bed alarm infrared can sense the movement of 6ft-26ft (with temperature changes), and can transmit the signal to the receiver of 918ft (open ground)

I want to have a second receiver. can i have two receivers. so i can hear one in my room and one in den.

We don't sell receivers separately, but you can order two sets at the same time, learn from each other and pair them according to the instructions to work together

If you cover up the indicator light will it affect the ability to sense motion?

No. It will not affect the sensor. The rectangular screen below the indicator light is the motion sensor, which you don’t want to cover up.

Pairing with multiple sensors. Do I have to turn the power off to sensor #1 before pairing sensor #2 or do I leave them both on?

When the receiver is off, press and hold the volume button for 3 seconds. After hearing the 'Di' sound, switch on the infrared sensor to be paired. Wait for 20 seconds and wave in front of the sensor
