Power Supply
The Data Collector has both a main power supply (lithium-ion battery pack) and a backup
power supply (lithium battery). In this manual, the words “main battery” refer to the lithium-ion
battery pack.
Low main battery power is indicated when the low voltage message appears on the LCD
screen. Replace the main battery or charge the battery pack as soon as possible after the
low voltage message appears.
Important! • Never remove both the main battery and backup battery at the same
time. Doing so causes all programs and data in Data Collector memory
to be lost.
• Never remove the main battery from the Data Collector while power it
turned on. Doing so can cause data stored in memory to be deleted. Be
sure to turn the Data Collector off before removing the battery.
• Use only the lithium-ion battery pack specified for the DT-810.
• The lithium-ion battery pack discharges naturally during the time it
takes for it to get from the factory to you. Make sure to charge the
battery pack before using it for the first time.
• Never allow the terminals of the lithium-ion battery to become shorted.
Doing so creates the danger of malfunction. Be sure to keep the battery
pack in its special case when transporting or storing it.
• Repeat charging of the lithium-ion battery pack gradually shortens its
ability to recharge. If you find that a fully charged battery pack provides
only little operation time, it probably means you need a new battery
pack.
• Whenever you do not plan to use the Data Collector for a long time,
load a fully charged battery pack into the Data Collector to protect
against power failure during non-use. Also, load a fully charged battery
pack before using the Data Collector after a long period of non-use.
