The r should be avoided to be installed in the position directly facing large air flow and close to heat source. (such as cold air outlet, exhaust fan, electric heater or heater nearby, etc.) Do not install the r directly in the sun and rain, and do not go near metal objects. 2. The r should be installed at a height of about 2 meters. The r trans detection is more sensitive than the straight line (human body directly facing the r) detection, generally should be installed in the side or top of the entrance gate, and adjust the induction to the appropriate position through the installation bracket, so as to achieve the best induction effect. 3. Obstacles and interference of other wirele signals should be minimized between r and receiver. Generally, the distance between r and receiver should be controlled at about 20 meters under the obstruction of a wall. 4. If the doorbell is short in receiving distance or fails, please check the detector battery or replace it. 5. If the environment temperature is too high (more than 30 degrees), the r distance will be shortened, which is a normal situation. 6. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the tures. Thank you! 7. Please allow 1-3mm measuring deviation due to manual measurement. 1 X r 1 X Receiver 1 X Manual
