 Treo™ 300
Turning your PCS Treo 300 on and off
Your PCS Treo 300 has two operating modes: a handheld mode and a 
wireless mode. You can turn the handheld mode and the wireless mode 
on and off independent of each other. When you turn on the handheld 
mode, you can use organizer applications such as Date Book Plus and To 
Do List. When you turn on the wireless mode, you can make or receive 
calls. You can also turn both modes on at the same time. When both the 
handheld and wireless modes are on, you can use the organizer 
applications as well as send and receive calls.
To turn handheld mode on and off, do any of the following:
©
Open the lid to turn it on, or close the lid to turn it off.
©
Press the power button.

To turn wireless mode on and off:

Press and hold the power button until you hear the confirmation 
tones and the Sprint banner appears. The ascending tone indicates 
wireless mode is now on and the descending tone indicates wireless 
mode is now off.
Using the keyboard backlight
If you have difficulty seeing your phone keyboard in dark environments, 
you can use the backlight to illuminate the keyboard. 
Note: 
When you turn on the keyboard backlight, the screen brightness 
automatically dims to conserve battery power. If you have difficulty seeing 
the screen in well-lit environments, be sure the keyboard backlight is off 
and adjust the display settings. See page 5 for details.
To turn the keyboard backlight on and off:
©
Press the power button twice in quick succession.

The backlight dims when a call is in progress and you do not press
