Battery Replacement
 Warning
To prevent possible electrical shock, fire, or personal injury:
• Batteries contain hazardous chemicals that can cause
burns or explode. If exposure to chemicals occurs, clean
with water and get medical aid.
• Do not disassemble the battery.
• Repair the Product before use if the battery leaks.
• Be sure that the battery polarity is correct to prevent battery
leakage.
• Do not short the battery terminals together.
• Do not disassemble or crush battery cells and battery
packs.
• Do not keep cells or batteries in a container where the
terminals can be shorted.
• Do not put battery cells and battery packs near heat or fire.
Do not put in sunlight.
The LOW BAT message will appear on the display approximately 6 hours prior to
the Survey Meter becoming inoperable. To ensure that the Survey Meter
operates to specification, change the batteries within 1 hour after the LOW BAT
message appears. The Survey Meter will function on one battery for
approximately 100 hours, allowing replacement of one battery at a time if the
Survey Meter must remain operational during battery changeover. Use either
regular or alkaline batteries for replacement purposes.
Batteries are accessible from the rear of the Survey Meter.
