If possible, the receiver should be placed right side up with its front toward the transmitter. Example 1 below shows the optimum placement of the receiver. If no line of sight is possible, place the receiver such that there is the minimum possible number of walls and obstacles between the transmitter and receiver. You can mount the receiver vertically as shown in Example 2 by using the 2 screw openings at the bottom. In this case, the operating range is reduced compared to mounting the receiver right side up. The receiver incorporates a directional antenna which prefers signals transmitted toward the front of the receiver. Therefore, the front of the receiver should always be facing toward the direction of the strongest transmitter signal. Note: This product will not work properly from within an enclosed metal cabinet.
