I can’t get the back cover on
1 Position the back cover over the phone and gently press the two clasps
(a), located at the top corners. Then press the two clasps (b) halfway
down either side of the phone.
2 Slide out the keyboard (see Slide out the keyboard ), and then press the
two clasps (c) at the bottom corners.
3 If you removed and reinserted or replaced the battery when the back
cover was off, you need to turn the phone back on: Press and hold
power on the upper-right corner of your phone until you see the
Palm logo on the screen (approximately five seconds). Then wait until
your phone completes startup.
Screen and performance
The screen appears blank
If you hold the phone up to your ear while on a call, the screen goes dark.
This is normal behavior. It prevents your accidentally tapping an item on the
screen and saves battery power. When you take the phone away from your
ear, the screen automatically turns back on, ready for use. If the screen
doesn’t turn on fast enough for you, tap the screen to wake it up.
The same behavior occurs anytime you’re on a call and the phone screen is
placed near another surface. The screen turns on automatically (if the phone
is still on) when you move the phone away from the other surface.
When the phone is on and idle, the screen first dims and then turns off. This
also is normal behavior, caused by the auto shut-off interval. You can adjust
this auto shut-off interval to be as long as three minutes (see
Set the interval
for turning the screen off automatically ). At first, the screen dims as a
power-saving measure. Just tap the screen to brighten it. Then, if your
phone remains inactive for the full interval you set, the screen turns itself off.
Press
power to turn the screen back on.
If you have inserted or replaced the battery, you need to press and hold
power until you see the Palm logo on the screen. Otherwise, follow
these steps in sequence if you can’t turn the screen back on:
TIP
If your phone does not turn on after you insert the battery and press and hold
power , you need to charge the battery (see Charge the battery ).
