Charging The Battery - GRAPHTEC midi LOGGER GL220 User Manual

Charging the Battery

Expected time required for charging:
The battery pack is charged by mounting it in the GL220, attaching AC adapter to the GL220.
(1) Mount the battery pack in the GL220 (see the previous section for the mounting procedure).
(2) Turn on the power to the GL220. (Please see Section 2.4, "Connecting the Power Cable and Turning on
the Power").
(3) The CHARGE LED lights.
• The GL220 is equipped with a temperature monitor function which starts automatic charging as soon
as it is cooled down. Therefore, depending on the internal temperature, charging may not be performed
immediately.
• When charging is attempted while the power is ON, charging may not be performed immediately even
if the temperature environment conforms to the specification. In such a case, set the Screen Saver
settings to ON or perform charging while the power is OFF.
• If input is being made directly from the DC power supply instead of the AC adapter, the DC voltage
must be at least 16V.
• The operating temperature range during charge is from 15 to 35°C.
