Note
Over Discharge and Long Periods of Storage
• If you do not use the instrument for an extended period of time with the battery pack connected to it, the battery pack may become
over discharged. This shortens the service life of the battery pack. To avoid over discharging, if you will not use the instrument for
one week or longer, charge the battery pack, remove it from the instrument, and store the battery pack away from direct sunlight in a
location that has an ambient temperature of 10°C to 30°C.
• When you store the battery pack for six months or longer, to replace the power that has been lost through self discharge, recharge
the battery using the instrument once every six months.
• Avoid storing the battery pack for an extended period of time when it is fully charged (after it has just been charged) or when it has
no power left (when the instrument will not turn on). Storing the battery pack under these conditions will degrade its performance and
reduce its longevity. It is better to store the battery pack when it is 40% to 50% charged. This is equivalent to the state the battery is
in after you turn off the instrument and charge an empty battery for an hour at room temperature.
• Use the instrument to charge the battery pack prior to its first use or if it has not been used for an extended period of time.
