6.1 Handling Precautions
Precautions for short-term storage (1 to 2 days)
If the DT-X5 is to be stored over holidays (including Saturday and Sunday), replace the battery pack (or
AA-size alkaline batteries) with brand-new one before starting the holiday. This will conserve the built-in
memory backup battery and ensure retention of data on the terminal.
If there is a possibility of the above or operator error (e.g., a fully charged battery has not been inserted),
practice system operation that maintains a backup to avoid loss of data due to consumption of the batteries.
Precautions for long-term storage (over one week)
Prior to long-term storage (over one week), always back-up data in the terminal to other memory storage
device. In addition, remove the lithium-ion battery pack or AA-size alkaline batteries before storage. This can
minimize overly discharging the installed battery and minimize consumption of the memory backup battery.
Do not store the removed battery pack or AA-size alkaline batteries at high temperature. Otherwise, it will
discharge at an accelerated rate. Note that the capacity after the battery if it is not used for 10 days at 60°C
will be 65%, and that after 20 days at 60°C will be 55%.
