The settings are indicated in 1/8", 1/4", 1/2" and 3/4" on one side of the cap,
and 3mm, 6mm, 12mm and 19mm on the other. First, turn the cap to align
the stationary pin with the vertical slot. Guide the cap to the preferred
horizontal slot position, then turn it just enough to engage the pin.
Note: The 1/8" (3mm) setting is not recommended for high humidity or foggy locations.
4. To install the sensor module on a rain gutter, simply position the Quick Clip bracket on the
lipped edge of the gutter and secure by tightening the thumb screw (Figure 12).
The sensor module can also be
mounted to any solid structure,
such as a fence or the side of a
roof using the Quip Clip bracket
and two stainless steel screws as
shown in Figure 13.
Note: For optimum signal
strength, the antenna wire should
hang straight down. Ensure
antenna is not in contact with any
metal object or structure.
