distance may be decreased. Please bear this in mind

when positioning the transmitters. Also the batteries may

be reduced in power for the thermo-hygro transmitter.

CHECKING FOR 868MHz RECEPTION

If the outdoor temperature and humidity data are not being

received within three minutes after setting up (or outdoor

display always show “- -.-” in the outdoor section of the

weather station during normal operation), please check the

following points:

1. The distance of the weather station or transmitters

should be at least 2 meters away from any

interfering sources such as computer monitors or TV

sets.

2. Avoid placing the transmitters onto or in the

immediate proximity of metal window frames.

3. Using other electrical products such as headphones

or speakers operating on the 868MHz-signal

frequency may prevent correct signal transmission

or reception. Neighbors using electrical devices

operating on the 868MHz-signal frequency can also

cause interference.

Note:

When the 868MHz signal is received correctly, do not re-

open the battery cover of either the transmitter or weather

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 around 100 meters from the

thermo-hygro transmitter to the weather 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 WEATHER STATION

The weather station provides the option of table standing

or wall mounting the unit. Before wall mounting, please

check that the outdoor data can be received from the

desired locations.
