"long-term" or "short-term. " Long-term denotes storage during times of long inactivity (over winter, end of
monitoring season, etc.). Short-term denotes storage during times the sonde will be used at a regular interval
(daily, weekly, biweekly, etc.).

1 Clean handheld.
If the HH's USB connector is contaminated, rinse it with
clean water and dry it.
To clean the HH's cable connector, follow directions in
section 6.18 for Connector Maintenance.
Wipe clean the HH's keypad, lens, and polymer case
with a cloth soaked in clean water and a few drops of a
dishwashing liquid that contains a degreaser. Take care not
to scratch the lens.
2 Short-term storage.
Keep the HH in a safe storage location and power it down
by pressing and holding the power button for more than
three seconds. Pressing the power button for less than three
seconds does not entirely power down the instrument
(Sleep mode) and may cause unnecessary battery drain.
3 Long-term storage.
Keep the HH in a safe location and remove the batteries
(and reinstall the battery compartment panel) to prevent
potentially harmful battery leaks.
Note: If the HH is stored for more than several days without
batteries, the GPS will take longer to obtain a location fix.
