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.
