signal is not received, relocate the units 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 
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 unit in water. 

 

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.
