●Is the charging adapter firmly plugged into the outlet?
●Is the charging adapter plug securely inserted into the main unit's
connector?
●The charging times might take up to 5 hours at the most depending
on the usage conditions such as the ambient temperatures and
usage times.
●If the battery status indicator lamp does not go out even though the
battery is charged for 5 hours or more, then since the device can be
considered to be defective, consult the retailer where it was
purchased.
●Is the charging adapter plug securely inserted into the main unit's
connector?
→ Unplug the plug from the main unit, and reinsert it
●Is there any foreign matter on the main unit's connector, or the
charging adapter plug?
→ Remove the foreign matter

are high or low?
→ Charge it in places where the room temperatures are 5 °C to 35 °C

● Even if the battery level indicator lamp (blue) is pulsating, it might not be
charged. (It is inoperable)
If the battery temperature is high, such as immediately after it has been
operated, it will not be charged even if the battery level indicator lamp
(blue) is pulsating since it automatically goes into standby for charging
until a temperature suitable for charging is reached.
→ Charge it until the battery status indicator lamp (blue) goes out
●Was the battery charged in places where the ambient temperatures
are high or low?
→ Charge it in places where the room temperatures are 5 °C to 35 °C
(P. 7)
●When the usage times are significantly shortened even though it is
being correctly charged, the battery's lifespan is over.
(The battery's lifespan varies depending on the usage conditions such
as ambient temperatures and usage times)
→ Replace the battery (P. 17)
