display will appear for a few seconds before the power is switched off when the
battery is too low to operate the unit.
To extend the battery life:
• Shut down the unit with the power switch when not taking measurements
or use the power save option to have the unit automatically turn off after 5
minutes.
• Store the unit in a cool dry place.
• Fully charge the battery before storing the unit for extended periods of time.
• Limit backlight use. The unit consumes 3X normal power with the backlight
on. Set the backlight time option to 10 seconds, or select "Button Control"
and keep the backlight off .
BATTERY REPLACEMENT
The lithium ion battery used in this unit should last for many years with normal use.
When it no longer powers the unit long enough to meet testing requirements it will
need to be replaced. Lithium ion batteries that are properly charged and stored do
not usually lose all capacity; they just have less capacity after hundreds of charge
cycles. This unit uses a custom battery assembly that is only available from LaMotte
Company. Battery replacement must be performed at a LaMotte authorized repair
facility. The water resistant housing of this meter should not be opened by the user.
Contact LaMotte Company by phone (1-800-344-3100) or email (tech@lamotte.
com) for a return authorization number.
MAINTENANCE
CLEANING
Clean the exterior housing with a damp, lint-free cloth. Do not allow water to enter
the light chamber or any other parts of the meter. To clean the light chamber and
optics area, point a can of compressed air into the light chamber and blow the
pressurized air into the light chamber. Use a cotton swab dampened with Windex
window cleaner to gently swab the interior of the chamber. Do not use alcohol; it will
leave a thin residue over the optics when dry.

Should it be necessary to return the meter for repair or servicing, pack the
meter carefully in a suitable container with adequate packing material. A return
authorization number must be obtained from LaMotte Company by calling 800-

of the meter is necessary, attach a letter with the return authorization number,
meter serial number, a brief description of problem and contact information
