palmOne Treo 600 Using Manual page 35

• As with any mobile phone, if you are in an area with no wireless coverage, your
Treo continuously searches for a signal, which consumes power. If you cannot
move to an area of better coverage, temporarily turn off Wireless Mode to conserve
battery power.
• Use the keyboard backlight (see page 23) only when you need it.
• Turn down the screen brightness (see page 121).
• Decrease the Auto-off setting in General Preferences (see page 128). This turns
off your screen automatically after a shorter period of inactivity.
