Important Guidelines When Using The Battery Pack - Bosch DCU 220 User Manual

Important guidelines when using the battery pack.

When installing or removing the battery pack take note of the following:

– avoid installing or removing the battery pack when DCU 220 is in Sleep mode.
Abruptly removing the battery pack may cause loss of
data or DCU 220 may become unstable.
– avoid touching the battery pack terminals or damage may occur, thereby causing
improper operation to it or DCU 220.
DCU 220's input voltage and surrounding temperature will directly affect the battery
pack's charge and discharge time:
– charging time will be prolonged when DCU 220 is turned on.
To shorten the charging time, it is recommended that you place the
DCU 220 in sleep or hibernation mode.
– a low temperature will prolong the charging time as well as hasten the discharge
time.
When using battery power in an extremely low temperature environment, you may

experience shortened operating time and incorrect battery level reading. This
phenomenon comes from the chemical characteristics of batteries. The appropriate
operating temperature for the battery is -10 °C ~ 50 °C (14 °F ~ 122 °F).
Do not leave the battery pack in storage for more than six months without recharging it.
