■ Display
When lighting is dim, you can turn on an EL (electro-luminescent) backlight for easier
viewing.
To turn on the EL backlight
There are two ways to turn on the backlight of the display.
Pressing LIGHT causes the backlight to turn on for about 15 seconds, and then turn
off automatically.
Pressing SHIFT and then LIGHT also turns on the backlight, but in this case the
backlight stays on as long as you keep performing key operations on the Digital Diary.
The backlight turns off automatically if you do not perform any key operation for about
15 seconds.
Leaving the backlight on for long periods greatly reduces battery life!
You can manually turn the backlight off by pressing LIGHT again.
Failure of the backlight to turn on indicates low battery power. Replace batteries as
soon as possible.
