MAINTENANCE AND CARE
Extreme temperatures, vibrations, and shock should be avoided to prevent
damage to the units.
Clean displays and units with a soft, damp cloth. Do not use solvents or
scouring agents—they may mark and damage the displays and casings.
Do not submerge in water.
Immediately remove all low powered batteries to avoid leakage and
damage. Replace with new batteries only, and of recommended size.
Opening the casings invalidates the warranty. Do not try to repair the units.
Contact La Crosse Technology for Repairs.
