Confirm that the DUN setting is turned off in the Bluetooth® application (see
"Using Dial-up Networking on Your Treo 650" on page 82).
Perform a soft reset (see "Soft Reset" on page 258).
The Treo Hangs Up When You Hold It to Your Ear
You may be pressing the onscreen Hang Up button with your cheek. Make sure
your face doesn't press against the screen. If this is uncomfortable, set the Disable
touchscreen when option on the Keyguard Preferences screen to turn on during
active calls (see "Auto-Keyguard and Touchscreen Lockout" on page 157).
The Treo Makes or Answers Calls When It's in a Briefcase or Pocket
Items in your briefcase or pocket may be pressing the onscreen Answer button, or
otherwise activating screen items. If this happens, be sure to press Power/End
to turn off the screen before placing it in your briefcase or pocket. You can also set
the Disable touchscreen when option on the Keyguard Preferences screen to
activate during incoming calls (see "Auto-Keyguard and Touchscreen Lockout" on
page 157).
Your Device Seems to Turn Off by Itself
If a system error and reset occurs and your device's phone was on before the
reset, then the phone automatically turns on after the reset. However, if the
Treo 650 can't determine if your device's phone was on before the reset, it does
not automatically turn on the phone (see "Turning Your Device's Phone On and
Off" on page 35).
