CARE OF YOUR METER

Store your meter in a clean, dry place. The protective carrying case provided is an ideal
storage place when the meter is not in use. If the meter has been left in a hot or cold
environment overnight or for an extended period, the calibration of the pin less mode may
be adversely affected. Under these conditions, allow the meter to acclimate to the
temperature conditions in which it will be used for minimum 1-2 hours, or as long as
possible.

Clean the meter with any biodegradable cleaner. Use the cleaner sparingly and on
external parts only. Keep cleaner out of the external connector.

Remove the battery if the meter will not to be used for one month or longer.
