■ Battery Precautions
Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of the
Digital Diary. Note the following precautions.
• Be sure that the positive (+) side of each battery is facing in the correct directions.
• Never mix batteries of different types.
• Never mix old batteries and new ones.
• Do not expose batteries to direct heat, let them become shorted, or try to take them apart.
• Never leave dead batteries in the battery compartment.
• Remove batteries if you do not play to use the unit for a long time.
• Replace batteries at least once every five years, no matter how much you use the unit during that
period.
• Never try to recharge the batteries that come with the unit.
• Should a battery leak, clean out the battery compartment of the unit immediately, taking care to
avoid letting battery fluid come into direct contact with your skin.
Keep batteries out of the reach of small children. If swallowed, consult with a physician imme-
diately.
2-3. EL backlight
• This unit is equipped with an EL backlight that allows easy viewing of display contents in a theater,
or anywhere else where lighting is dim.
• Note, however, that frequent or extended use of the EL backlight shortens battery life.
The following shows how backlight use affects battery life under controlled test conditions.*
* Test Conditions
• “Battery Life” is the number of hours before battery failure when the unit is left on with 5 minutes of
a processing operation and 55 minutes of continuous display only (no processing operation) per
hour, plus the backlight operation described below.
• “Backlight Operation” is the number of minutes the backlight is turned on per hour during the
display only (no processing operation) period.
Backlight Operation Battery Life
3 minutes per hour Approximately 80 hours
15 minutes per hour Approximately 45 hours
