2-1. Appearances and display indicators
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
turn on for about 15 seconds, and then turn off automatically. Pressing
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
Failure of the backlight to turn on indicates low battery power. Replace batteries as soon as possible.
