Note:
If you remove the battery, the date and time settings will be erased after about one day. The next time you turn on the P-4000, the date and time setting screen will be displayed. If you want to change the settings at any time, select Settings on the Home screen, then select Date and time.
Conserving Battery Power
To conserve battery power and protect the LCD screen, the P-4000 has two power-saving features. If no button has been pressed and there has been no activity for 10 minutes, the backlight on the LCD screen is turned off. After 15 minutes, the power is turned off.
Note:
You can change the number of minutes for these settings; select Settings on the Home screen, then select Power Save.
◗If the screen goes dark because the backlight is turned off, press any button on the P-4000 to turn it back on.
◗If the P-4000 has been powered off, you need to turn it back on with the P power switch.
Note:
The power is also turned off if the P-4000 gets too hot. If this happens, let it cool before turning it back on.
