2.  Clip the remote temperature transmitter onto the 

bracket. 

 

Note:

  

The mounting surface can affect the transmission range. If, for instance, 

the unit is attached to a piece of metal, it may then either reduce or 

increase the transmitting range. For this reason, we recommend not to 

place the unit on any metal surfaces or in any position where a large 

metal or highly polished surface is in the immediate vicinity (garage 

doors, double glazing, etc.). Before securing in place, please ensure that 

the Temperature Station can receive the 915MHz signal from the 

temperature transmitter at the positions that you wish to place them. 

 

CARE AND MAINTENANCE:

 

 

Extreme temperatures, vibrations and shocks should be avoided as 

these may cause damage to the unit 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. Furthermore, fix all parts in 

place where the units are adequately protected against moisture 

and rain. 

 

Immediately remove all low powered batteries to avoid leakage and 

damage. Replace only with new batteries of the recommended 

type. 

 

Do not make any repair attempts to the unit. Return them to their 

original point of purchase for repair by a qualified engineer. 

Opening and tampering with the unit 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.
