LaMotte WaterLink 3 Express Lab - Manual (Page 25)

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. The water resistant housing of this meter should not be
opened by the user.

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.
REPAIRS 
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 800-344-3100, ext. 2 (US only) or 410-778-3100, ext. 2, faxing
410-778-6394, or emailing [email protected]. Often a problem can be
resolved over the phone or by email. If a return of the meter is necessary,
attach a letter with the return authorization number, meter serial number, a
brief description of problem and contact information including phone and
FAX numbers to the shipping carton. This information will enable the service
department to make the required repairs more efficiently.
