Important Placement Guidelines
A. To maximize wireless range, place units away from large metallic items, thick walls, metal surfaces, or other objects that may limit wireless communication.
B. To prevent wireless interference, place both units at least 3ft (1 m) away from electronic devices (TV, computer, microwave, radio, etc.)
Important!! Before placing the digital pool thermometer in the water, please tighten the thermometer cover, otherwise water may enter. If you find water mist on the screen of the wireless pool thermometer lid, please unscrew the lid to dry and then use it. Please feel free to refer any usage problems to us.
BLANK Screen may indicate low/weak batteries. Check metal contacts for battery leakage or corrosion.
