cable (USB Type A connector) into the wall adapter. Plug the wall adapter into
an AC outlet. Reinsert the USB port plug after charging.

(USB Type A connector) into a USB port on the computer. Reinsert the USB
port plug after charging.
The battery icon will show no bars and flash when the unit first turns on. Then
the indicator will indicate the battery status by showing 0, 1, 2, 3 or 4 bars.
It will take 5 hours to fully charge a low battery. The battery icon will flash
when the battery is charging. The battery icon will show four bars and stop
flashing when it is fully charged. The charging circuit will automatically switch
to a float charge when the battery is fully charged. The charger may remain
connected. Some computers will NOT supply power to their USB ports during
standby operation. The wall charger will charge the unit continuously.
The battery icon will show no bars and continuously flash if the battery is
getting low but the unit will still operate normally. A "Low Battery" message on
the status bar of the display will replace the time when the battery voltage is
too low for proper operation and accuracy may be degraded. A "Shutdown Low
Batt" message on the 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.
