6. Operation

Gently set the tightly closed unit on the water‘s surface.

Wait until the temperature display shows a stable value. The temperature

of the inner housing will take some time to match the water tempera-

ture.

Caution!

Do not throw the unit into the water. Do not use the unit as a toy or spor-

ting equipment.

Mind your pets. Do not allow them to use the unit as a toy.

Do not submerge the unit. It is designed to ﬂoat and work on the water‘s

surface.

Do not use the unit in water that is too hot (>158ºF/70º) or icy water.

Remove the unit from the water when not in use.

7. Range

The free ﬁeld range, i.e. the range of the line of sight contact between the

transmitter and the receiver is 300 ft. under optimum conditions. Walls

and even reinforced concrete can be penetrated, which does, however,

reduce the range. A reduced range can occur due to the following rea-

sons:

- High-frequency interference of all kinds

- Built structures and vegetation of all types

- The distance of the transmitter or receiver from conductive surfaces or

objects (even to the human body or the ground) has an effect on the

transmission characteristics and therefore the range.

- Wide band interference in built up areas can reach levels that reduce

the signal-noise ratio throughout the frequency band which results in

a reduced range.

- Devices with adjacent working frequencies can also inﬂuence the re-

ceiver.

- Badly shielded PCs can irradiate the receiver and limit its range.
