Battery Safety

The lithium battery that powers the device contains 

 

inflammable materials such as lithium organic solvent, 

 

and other chemical ingredients. Explosion or fire may 

 

result if the battery is not handled correctly. To avoid 

 

an accident, follow these guidelines:

• 

Do not open enclosure if the area is known to be 

 

hazardous

• 

Do not replace batteries in a hazardous area

• 

Do not stack or jumble up batteries

• 

Do not heat batteries above 95° C

• 

Do not disassemble batteries

• 

Do not recharge lithium batteries

• 

Do not apply pressure to, or deform, batteries

• 

Do not solder batteries

• 

Do not dispose of batteries in fire

•  Insert battery with correct polarity.

Recommended Replacement Batteries

 

  Panasonic P/N: CR 2/3A

 

  Varta P/N: CR 2/3A

 

  Fuji P/N: CR 2/3 8.L

Initial Start-Up

 

In a non-hazardous area, remove the protective battery 

 

insulating tab between the battery and clip to activate 

 

the display.
