Pressing the battery pack’s TEST button turns on the indicator that shows the battery level; this is not a
malfunction. The indicator will turn off after a while.
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 the
instrument, 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 in a cool place (10°C to 30°C)
away from direct sunlight.
• When you store the battery pack for six months or longer, to replenish the power that is 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 best to store the battery
back 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 pack for about 2.5 hours at room temperature.
• Charge the battery pack prior to its first use or if it has not been used for an extended period of time.
