7. Precautions
7.1 Handling
Precautions for short-term storage (1 to 2 days period)
• If the DT-X11 is to be stored over holidays (including Saturday and Sunday), replace the
HA-A20BAT (or DT-5025LBAT) battery pack with fully charged one before it is stored. This
will conserve the memory backup battery and ensure retention of data on the DT-X11.
• If there is a possibility of the above or operator error (e.g., a fully charged battery pack has not
been installed), practice system operation so that a backup to avoid loss of data due to low
battery voltage is carried out periodically.
Precautions for long-term storage (over one week period)
• Prior to long-term storage (over one week period), always back-up data. In addition, remove
the battery pack and memory backup battery before storage. This can minimize overly
discharging the battery pack and the memory backup battery.
• Do not store the removed battery pack and memory backup battery at high temperature.
Otherwise, they will discharge at an accelerated rate. Note that the capacity of the battery if it is
not used for 10 days and is kept at 60°C will be 65%, and that for 20 days and is kept at 60°C
will be 55%.
