CAUTION
Wait for at least 10 minutes after turning off the power to this device
before removing the battery.
Otherwise, there is a danger of electric shock or a burn.
When the battery is removed, some settings and internal opera-
tion status data will be lost.
Please dispose of used batteries properly, in accordance with local
bylaws and regulations.
When discarding this device, remove the battery following the procedure given
below, and then dispose of it appropriately, following local regulations.
Battery removal procedure
(1) Remove the case.
Insert the flat head of a screwdriver into the grooves (on the top, bottom,
right and left sides) between the front panel
and the case, and then gradually pull the case
off while gently prying with the screwdriver.
(2) Remove the battery from the battery holder.
Pull the battery upward.
Handling Precautions
• The SDC45V/46V has a memory backup
battery. The replacement battery listed below is available.
