Be sure instrument is turned off and disconnected from all power sources. Wipe with
a clean, dry lint-free cloth. Do not use abrasive cleaners or solvents.
Recharge as needed. There are no pre-designated intervals at which to recharge as
long as you are using the unit regularly. Avoid discharging completely on a regular
basis, as this can impact overall life.
If storing for more than one month, charge completely before storage, and recharge
approximately every three months to avoid full discharge. Store in cool temperatures, mild
humidity, and away from direct sunlight (See GENERAL SPECIFICATIONS section).
Leaving in a vehicle or other confined spaces in extreme hot temperatures can lead to decrease
in service life, overheating, or fire. Extreme cold temperatures below the specified storage range
can also harm performance and service life. Keep away from corrosive chemicals and gases.
After taking out of storage, inspect visually to make sure device and all accessories look
satisfactory. Allow unit to return to ambient conditions before recharging.
