INSTALLING THE DRY BATTERIES FOR MEMORY BACK-UP
This is a function which preserves the preset memory and most-recent memory functions, (n the event of a power failure, or if the
AC mains cord is disconnected from the household AC mains outlet (during AC operation), or should the batteries fail, the memory
back-up batteries will preserve the preset memory and the most-recent memory functions of this unit.
■ Memory back-up batteries (four R6/LR6)
1. Open the memory back-up battery compartment cover,
2. Insert four “R6/LR6" size (UM-3 or equivalent, not included) batteries into the battery compartment, making sure that the
batteries are installed in the designated numerical order and that the proper polarities are maintained,
3. Close the cover.
The life of the memory back-up batteries is about one year.
While exchanging the memory back-up batteries, be sure to connect the AC mains cord both to the unit and household AC
mains outlet.
•To prevent erasing the memory
In case the memory back-up batteries are not used, power
failure (when using AC mains) or the following operations
cause the erasure of the memory:
When using AC mains: unplugging the AC mains cord from
the household AC mains outlet.
When using battery power (“R20/LR20"): inserting the AC
mains cord only into the AC socket of this unit.
If one of the above cases occurs, enter the program into
the memory again,
in order to avoid the accidental erasure of the program in
the memory, using the memory back-up batteries (4 “R6/
LR6" size, UM-3 or equivalent, not included) is recom­
mended.
