Battery Replacement
When the battery level is low (one bar remains on the battery icon), an alarm will sound
repeatedly at five minute intervals. When the battery is nearly exhausted, a unique
combination of audible, LED, and LCD backlight alerts will display for approximately 10
seconds (before the unit turns off completely).
Required Items:
• Phillips-head Screwdriver
• Replacement Battery = SB-AA02 (Lithium ½ AA Battery, 3.6V/1.2Ah)
NOTE: Replacement of the battery in dangerous regions with potential for
explosion is strictly prohibited. Replacement of components can hinder intrinsic
safety function.
NOTE: Replacement battery kits should be purchased from the same retailer
that the device was originally purchased from.
NOTE: The device must be recalibrated following battery replacement.
NOTE: Before disassembling, power off the device according to the instructions
in this operation manual.
