■ Power Supply
Your Digital Diary is powered by two AA-size alkaline batteries, and its memory is
protected by a single CR2032 lithium battery.
Low Battery Warning
Failure of anything to appear on the display after you turn on power or appearance
of the low battery message, “MAIN BATTERIES WEAK! REPLACE THEM! UNIT
WILL NOT TURN ON AGAIN!” (followed by the display turning off in about 10
seconds) normally indicates that main battery power is low.
Note, however, that pressing the RESET button on the back of the unit and then
performing steps 1 and 2 of the procedure under “When to press N for “no”” above
can sometimes restore normal operation. When the low battery message appears
on the display even if you perform these steps, it means you should replace the main
batteries as soon as possible.
Note
•
Take care that you do not make a mistake and delete memory contents at this
time.
Important!
•
Replace batteries only when low battery power is indicated by failure of the Digital
Diary to turn on when you press the ON key. Do not replace batteries as long as
the Digital Diary turns on normally when you press the ON key.
•
There is not low battery warning for the back-up battery. Be sure to replace the
back-up battery once every 5 years.
•
Be sure you keep a separate copy of all important data that you store in the Digital
Diary.
