Important!
Always keep backup of all important data!
• The battery pack powers normal operation and also provides power required to
maintain memory contents, while the backup battery provides backup power to
maintain memory contents. Because of this, you should not remove the battery pack
if the backup battery is dead. Removing the battery pack while the backup battery is
dead causes data in the memory to be corrupted or lost. Note that once data is lost it
cannot be recovered. Always keep backup of all important data.
• The charge of a battery pack when you purchase it may be depleted due to testing at
the factory or natural discharge during shipment and storage. Be sure to charge the
battery pack before you use it.
• The life of a battery pack is limited, and charging a battery pack causes it to
gradually lose its ability to maintain the charge. If your battery pack seems to
require charging very frequently, it probably means it is time to purchase a new one.
• If a battery pack is used past the end of its service life, it may swell up in size. In such
a case, replace the battery pack with a new one.
• It takes approximately 4 hours with the main battery pack installed in the terminal
for the backup battery to be charged fully.
• If a battery pack is installed in the Smart Device, it will still work when the battery
cover is open. However, the battery cover should be closed when using the Smart
Device in case the battery pack unexpectedly drops out and causes data loss.
