18. Changing batteries:

Battery change only in the thermo-hygro-sensor:

1. Open the battery cover

2. Remove the old batteries and insert with new ones of the rec-

ommended type and replace the cover

Once the sensor is powered up, press and hold the PLUS(+) key for

approx. 2 seconds in the normal display mode, the base station will

sound a short beep and synchronize to the sensor otherwise no

weather data will be received.

Battery change only in the base station:

1. Connect power adaptor to base station and power outlet.

2. Open the battery cover located at the back of the base station.

3. Remove the old batteries, insert with new ones of the recom-

mended type and replace the cover

This method of battery replacement will result in no loss of MIN/MAX

and history data. However in case of possible power failure, the base

station will lose the MIX/MAX and all weather data recordings and will

need to be synchronized to the sensors again by pressing the

PLUS(+) key for 2 seconds.

Note:

When batteries require replacement for the base station, the low

battery indicator will light up on the LCD.

Please participate in the preservation of the environment

by properly disposing of all used-up batteries and accu-

mulators at designated disposal points. Never dispose of

batteries in a fire as this may cause explosion, risk of fire

or leakage of dangerous chemicals and fumes

19. Interferences and problems with operation

Problem & cause Remedy

Distance between

transmitters and re-

ceiver too long.

Reduce distance between transmitters

and receiver to receive signal

High shielding materi-

als between the units

(thick walls, steel, con-

crete, isolating alumi-

num foil and etc.)

Find a different location for sensors

and/or receiver. See also Item ‘Trans-

mission Range’ below.

Interference from other

sources (e.g. wireless

radio, headset,

speaker, etc. operating

on the same frequency)

Find a different location for the sensors

and/or base station. Neighbors using

electrical devices operating on the

433MHz signal frequency can also

cause interference with reception

No Reception after

adding extension ca-

bles

Find a new location for the sensors

and/or base station. Recommend not

adding more than 10 meter extension

cables between units to the existing

cable lengths as this will increase the

chance data reception problems.

Reception then no

reception - loss of

transmission signal

from the sensor to the

base station

Press and hold the PLUS(+) key for 2

seconds to synchronize the base sta-

tion to the sensors for weather data

reception. If still no signal, then

change the sensor batteries and syn-

chronize the units again.

Poor contrast LCD or

no reception or low

batteries in sensors or

receiver.

Check the LCD contrast setting or

change batteries (check low battery

indicator on the LCD)

Quite frequently interferences are only of a temporary nature and may

be easily overcome. If there are wireless headsets, remote babysit-

ters or other devices working on 433MHz in your house or in the vicin-

ity, their switch-on time is mostly limited. Furthermore most of these

devices allow the change to an interference-free frequency. Such

measures will effectively overcome interferences.
