Note:
When the 433 MHz-signal is received correctly, do not re-open the battery cover of either the remote
temperature/humidity sensor or weather projection station, as the batteries may spring free from the
contacts and force a false reset. Should this happen accidentally then reset all units (see “Setting up”
above) otherwise transmission problems may occur.
The transmission range is approximately 330 feet (100 meters) from the remote temperature/humidity
sensor to the weather projection station (in open space). However, this depends on the surrounding
environment and interference levels. If no reception is possible despite the observation of these factors, all
system units have to be reset (see “Setting up” above).
POSITIONING THE REMOTE TEMPERATURE/HUMIDITY SENSOR:
Each transmitter is supplied with 2 wall mounting screws and plastic anchors. To wall mount simply:
1.
Secure the wall base onto a desired wall using the screws and
plastic anchors.
2.
Insert the transmitter to the wall base.
Note:
Before permanently fixing the
transmitter wall base, pace all units in the desired locations to check that the
outdoor temperature and humidity readings are receivable. In event that the signal is not received, relocate
the transmitters or move them slightly as this may help the signal reception.
CARE AND MAINTENANCE:
•
Extreme temperatures, vibration and shock should be avoided as these may cause damage to the
units and give inaccurate forecasts and readings.
•
When cleaning the display and casings, use a soft damp cloth only. Do not use solvents or scouring
agents as they may mark the LCD and casings.
•
Do not submerge the units in water.
•
Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new
batteries of the recommended type.
•
Do make any repair attempts to the units. Return it to their original point of purchase for repair by a
qualified engineer. Opening and tampering with the units may invalidate their guarantee.
•
Do not expose the units to extreme and sudden temperature changes, this may lead to rapid changes
in forecasts and readings and thereby reduce their accuracy.
