Make a Phone Call

Tip

If you'd like to exert some control over the indicator light on your Treo, you might want to consider using a third-party application, such as LEDOff or Butler. Some people get annoyed by the indicator light at night, and these applications allow you to turn it off. Butler is actually capable of doing much more than just providing control over the indicator light. To find out more, check out Butler at Hobbyist Software (http://www.hobbyistsoftware.com/) or LEDOff at FreewarePalm (http://www.freewarepalm.com/utilities/ledoff.shtml).

Making a call on your Treo device is easy and can actually be carried out in a variety of ways. Because I don't want to assume that you've synchronized contacts from a desktop PIM application, such as Microsoft Outlook, I'm going to focus on showing you how to dial a number as opposed to dialing via a contact. Follow these steps to make a phone call on your Treo:

1.	If the mobile radio isn't turned on, hold down the Power/End button until you hear a tone and a screen appears that indicates you're being connected to the wireless network.
2.	After you are connected to the network, press the Phone/Send button to launch the Phone application.
3.	Dial the phone number by pressing number keys on the keyboard (Option Lock is on by default) or by tapping numbers on the onscreen Dial Pad with the stylus (see Figure 2.12). Figure 2.12. You dial a number in the Phone application by pressing number keys on the keyboard or tapping the numbers on the onscreen Dial Pad.
4.	Press the Phone/Send button again to dial the number. The number is dialed and you are connected on the call (see Figure 2.13). Figure 2.13. After you're connected on a call, you can switch to the speakerphone, put the call on hold, access the Dial Pad, or mute the microphone.
5.	To end the call, press the Power/End button or tap the Hang Up All button on the screen.

Notice in Figure 2.13 that several options are available when you're on a call. You can easily tap a button on the screen to switch to the speakerphone, put the call on hold, access the Dial Pad, or mute the microphone. You can just as easily use the five-way navigator to navigate between these buttons and issue phone commands. You can also originate another phone call and conference the calls together, but that's a more advanced topic for Chapter 7, "Using Your Treo as a Mobile Phone."

Note

A soft reset is the Treo equivalent of a system reboot on a desktop computer when you shut down the computer and restart it. This is in contrast to a system reset and a hard reset, which are increasingly serious in terms of how they affect your device. All three types of resets are covered later in the chapter in the section "Reset Your Treo."

In addition to making a call, if you're new to your mobile phone service, you might need to access phone information on your device to help remember your mobile phone number. Follow these steps to look up the phone number for your Treo:

1.	If the mobile radio isn't turned on, hold down the Power/End button until you hear a tone and a screen appears that indicates you're being connected to the wireless network.
2.	After you are connected to the network, press the Phone/Send button to launch the Phone application. Tip You might find that you need to adjust the phone's volume while you're on a call. Just press up or down on the Volume button on the left side of your Treo to adjust the call volume.
3.	Press the Menu button to open the menus for the Phone application.
4.	Press the Right button twice to activate the Options menu, and then scroll down and select Phone Info. The Phone Info screen that appears displays a variety of information about your device, including its phone number (see Figure 2.14). Figure 2.14. The Phone Info screen includes a lot of information you probably don't care to know, but it also happens to show your mobile phone number.

I explained how to dial a phone number, but I didn't clarify what to do to answer an incoming call. I'm sure you've already guessed, but the Phone/Send button is all you have to press to answer an incoming call.

Now that you have a phone call under your belt, you can move on to sending a text message.

Tip

No one appreciates a noisy mobile phone ringing in a theater or some other place where noise is undesirable. Treo devices are one of the only mobile phones that include a hardware ringer switch to instantly turn off the phone's ringer. The switch is on the top of the phone near the expansion card slot. Just slide it over to the right, and your phone's ringer won't bother you during a movie. Chapter 7, "Using Your Treo as a Mobile Phone," explores different settings for how your phone vibrates (or not) in lieu of the muted ringer.
