Maintenance
The following guidelines will help you to take care of the JACOB JENSEN
Thermometer II Silver Version so that you can enjoy it for many years.
1. Keep the thermometer dry at all times. If it becomes wet, wipe it dry
immediately. Liquids can contain minerals that might corrode the
electronic circuits.
2. Use and store the thermometer only under normal temperatures.
Temperature extremes can shorten the life of electronic components,
damage batteries and distort or melt plastic parts.
. Handle the thermometer gently and with care. If it is dropped, circuit
boards can be damaged, resulting in malfunction.
4. Keep the thermometer free from dust and dirt, to avoid the premature
wear of parts.

old or weak batteries as they might leak chemicals that will destroy the
product.

thermometer may cause malfunction and will invalidate the warranty.
