5.4 Care and Maintenance
● Keep the tag dry. Precipitation, humidity and all types of liquids or moisture can contain min-
erals that will corrode electronic circuits.
● Do not use or store the tag in dusty, dirty areas. Its moving parts can be damaged.
● Do not store the tag in hot areas. High temperatures can shorten the life of electronic devices,
damage batteries, and warp or melt certain plastics.
● Do not store the tag in cold areas. When it warms up (to its normal temperature), moisture
can form inside, which may damage electronic circuit boards.
● The operating temperature of the tag is 0 to 50 ºC (32 - 122 ºF). Do not operate the tag outside
this temperature range.
