C. How to Detect the Status of Dual Battery
Attention: Please power off your VP-2117 before replacing the
battery; it may cause permanent damage if the battery accidently
touches other metal electronic parts.
VP-2117 equips a 512 KB SRAM with Dual
battery design to ensure the persistence of
data even in the case of total power loss.
Additional S512/256 chip battery backup
SRAM is no longer required.
The Dual battery provides 512 KB SRAM
with continuous power supply to retain the
data stored within up to 5 years; this dual
battery design allows for the replacement of
one of the batteries without losing power
and thus not losing the data stored in the memory. (Warning: Please do not take
out these two batteries at the same time or the data will be lost during this
period of non-power.)
