Network Connection

Signal Strength Is Weak

Become familiar with low coverage areas where you live, commute, work, and
play. Then, you will know when to expect signal strength issues.
If standing, move about 10 feet in any direction.
In a building, move near a window. Open any metal blinds.
In a building, move outdoors or to a more open area.
Outdoors, move away from large buildings, trees, or electrical wires.
In a vehicle, move your Treo level with a window.

The Treo Won't Connect to the Mobile Network

Try our suggestions above for weak signals.
Turn off Wireless Mode and turn it on again (see page 27).
Perform a soft reset (see page 152).

The Treo Hangs Up When I Hold It to My Ear

You may be accidentally pressing the onscreen Hang Up All button with your
cheek. Try holding the phone so your face doesn't press against the screen. If this
is not convenient, you may want to set the Disable touchscreen when option on the
Keyguard Preferences screen to turn on during active calls (see page 137).

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, set the Disable touchscreen when
option on the Keyguard Preferences screen to activate during incoming calls (see
page 137).

Wireless Mode Seems to Turn Off by Itself

If a system error and reset occurs, Treo automatically turns on Wireless Mode if it
was on before the reset. However, if the Treo can't determine whether Wireless
Mode was on before the reset, it does not turn on automatically (see page 27).
