When the “LOW BATTERY” Symbol Appears
When “LOW BATTERY” is displayed, immediately replace the
operation battery with a new one.
The operation battery holder is indicated as “For OPERATION” in
the battery compartment.
If the battery level is low, the alarm may not sound, or similarly
the Backlight may not function or remain on for less than the set
interval. Continued use of the Organizer with low battery can alter
or clear the memory contents. Memory contents may be lost if the
battery is improperly replaced or if the following instructions are
disregarded.
Note:
• After the battery replacement, check also that the Backlight
functions properly.
Caution:
• PC Link may not be available when the battery level is low.
• Under the low battery condition, new data entry and editing of
existing data may not be performed in some modes. Also clock
settings, step count function of the pedometer, and the calorie
calculation may not be available.
When the Backlight Won’t Function
When the Backlight cannot be turned on (except when “LOW
