About Lithium Batteries
- Please store the lithium battery LS14250 in a place that is 20
℃
or less.
- When using lithium batteries other than LS14250 produced by SAFT, such as
CR2, product specifications cannot be guaranteed nor can the performance of
some functions, such as the battery warning function.
- Please avoid using the CR2 in the following situations:
Using the unit in an environment below 0
℃
or above 60
℃
Exposing the CR2 to continuous vibration such as in transportation
- When using a CR2 lithium battery, the tube is not necessary.
- To maintain waterproof capacity, when changing batteries also change the
rubber packing and the drying agent (silica gel). When using a CR2 lithium
battery, please purchase the optional Maintenance Set (TR-00P1) to replace
the rubber packing and silica gel.
