Page 18 Introduction to Your Treo™ 180g Communicator
Turning your Treo on and off
Your Treo communicator 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.
■ Press and release the rocker switch.
■ Press any application button on the front of your communicator.
To turn wireless mode on and off:
■ Press and hold the power button until you hear the confirmation tones to turn wireless mode
on and off. The ascending tone indicates wireless mode is now on and the descending tone
indicates wireless mode is now off.
Using the backlight
If you have difficulty seeing the information on your communicator in dark environments, you can
use the backlight to illuminate the images on the screen.
Note: If you have difficulty seeing the screen in well-lit environments, adjust the contrast instead
of using the backlight. See page 13 for details.
To turn the backlight on and off:
■ Press the power button twice in quick succession.
Backlight tips:
■ You can assign the full-screen pen stroke to activate the backlight. See page 174 for details.
■ The backlight turns on automatically when an incoming call “wakes up” your communicator.
■ The backlight also turns off automatically (after a period of inactivity) with the Auto-off
feature. See page 180 for details.
