Turning your smartphone on and
off
You can use the Palm OS
®
organizer features of your Treo 650 smartphone
independently of the wireless features and applications. In other words, the screen
and phone are designed to be turned off and on separately.
Waking up the screen
To use the Palm OS organizer features when your smartphone is off, you need to
wake up the screen. You can also turn off your smartphone’s screen without turning
off your smartphone’s wireless features.
1. Press Power/End to wake up the screen.
2. Briefly press Power/End to turn off the screen.
Turning your phone on and off
When you turn on your phone, it connects to a mobile network so that you can make
and receive phone calls and use other wireless services.
1. Press and hold Power/End to turn on your phone. If Sound On is on you’ll hear
a series of ascending tones. (See “Setting the Ringer switch” on page 184 for
more information.) After your phone locates a signal, you can use the phone and
Internet features (if supported by the local network).
2. Press and hold Power/End again to turn off your phone. If the Ringer switch is
set to Sound On, you‘ll hear a series of descending tones. When your phone is off,
your Treo smartphone is not connected to any mobile network. You can still use the
organizer and other Palm OS features. This is ideal for airplane flights and for
maximizing battery life.
The indicator light flashes
green when your phone is
on and you’re inside a
coverage area. If you’re
outside a coverage area,
the indicator light flashes
amber.
Your Treo 650 smartphone
includes a keyboard
backlight for low-light
conditions. The keyboard
backlight activates
automatically when the
screen turns on. It turns off
automatically when the
screen turns off and when
an active call lasts longer
than a minute.
You can also press any
application buttons on the
front of your phone to wake
up the screen and go
directly to the application
linked to that button.
