Power Supply
The Data Collector has both a main power supply (two AA (LR6)-size alkaline batteries or a
lithium-ion battery pack) and a backup power supply (lithium battery). In this manual, the
words “main batteries” refer to both alkaline batteries and the lithium-ion battery pack.
Low main battery power is indicated when the low voltage message appears on the LCD
screen. Replace the main batteries or charge the battery pack as soon as possible after the
low voltage message appears.
Important!
• Never remove both the main batteries 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 batteries 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 batteries.
• Use only AA (LR6)-size alkaline batteries or the specified 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 two new alkaline batteries or a fully charged battery pack into the
Data Collector to protect against power failure during non-use. Also,
load new batteries or a fully charged battery pack before using the Data
Collector after a long period of non-use.
