Most Pocket PC PDA models feature similar external hardware configurations with the exception of the
SD slots on the newer series, the fingerprint scanner on the 54xx series, and small variations in button size and location.
The front of the iPAQ contains most of the items that you will use as
you work with the iPAQ. From left to right, top to bottom, the features are
- Microphone The built-in microphone is useful for voice dictation and voice control software. On the 5400 series iPAQs the microphone is on the bottom left. On the H1910 it is on the very top of the unit.
- Light sensor This sensor will automatically adjust the side lighting based upon the light in the room.
- Power indicator/Charging/Alert light This light glows solid amber if your iPAQ is connected to AC power and fully charged. It is off if your iPAQ is running on battery power, flashes amber if your iPAQ is charging, and flashes green if you have an alert or reminder. On the 5400 series iPAQ it is on the left and is one of three indicator lights. The other two lights are for 802.11b wireless connection and Bluetooth connection. On the H1910 a single indicator light in the top middle is also the power button.
- Speaker Built-in speaker for any sound coming out of your iPAQ. On models prior to the 38xx series iPAQs, the speaker was hidden inside the Navigation Disc (see later in list).
- Power button This button turns your iPAQ on and off. It also turns the side light off and on when held down for one second.
- Screen This is a 320×240-pixel touch-sensitive screen.
- Button One (Calendar button) This programmable button is by default set to open the Calendar, but can be modified to perform a number of functions.
- Button Two (Contacts button) This programmable button is by default set to open Contacts.
- Button Three (Inbox button) This programmable button is by default set to open the Inbox on all iPAQs since the 37xx series. On 36xx series or older iPAQs it opens the Quick Menu application.
- Button Four (iTask button) This programmable button is by default set to open the iPAQ iTask program, which is used to switch between running applications or to shut down open applications. On older iPAQ models, this button opened the Compaq task switcher. On the H1910, this button will return you to the Today screen.
- Navigation Disc A multiposition disc for navigating through applications and data. This disc’s size and shape vary by model of iPAQ.
- Biometric Fingerprint Reader This is on the 54xx series iPAQs only and compares the fingerprint of the device user against a stored fingerprint to authenticate the user. If the fingerprints do not match, the device will not allow access.
Looking down on the top of the iPAQ, note three controls (from left to right):
- Headphone jack Use this jack to plug in stereo headphones and listen to any of the sounds the iPAQ produces (incidentally, it makes a good MP3 player).
- Top microphone hole This is a small hole that is linked to the internal microphone like the hole on the front of the iPAQ. It lets you record a sound by pointing your iPAQ at the sound source (on the 54xx series, this hole is on the bottom).
- Secure Digital slot On the 38xx, 39xx, 19xx, and 54xx series iPAQ this slot allows you to insert Secure Digital (SD) memory cards, or SD-based devices such as a digital camera (except on the H1910, which does not support the SDIO—Secure Digital Input/Output—standard, so the slot can only be used for memory).
- Infrared port This port is used for sending and receiving information from other infrared devices. On the H1910, this port is on the left side of the iPAQ. More information on this is in the “Beaming Data for Easy Transfer” section later in this chapter.
- Stylus The stylus is conveniently stored inside the body of the iPAQ.
Press the silverbutton to pop the stylus out of its slot if you have a 37xx series of iPAQ or earlier. If you have a 38xx series iPAQ or later, the stylus is released by pushing it down so it pops out. To slide the H1910 stylus out of its slot, slide your finger or thumb along the back-right corner in an upward motion.
On the bottom of the iPAQ you will find four items (from left to right):
- Adapter jack Use this jack to plug in an external charger. This jack doesn’t exist on the 38xx, 39xx, or H1910 iPAQs, as they must be charged through the Sync port.
- Hard reset switch (36xx and 37xx series iPAQs only) Use this switch for hard resetting the device (this will wipe out the memory of the device). Hard resetting is not something you want to do by accident, so the switch to cut and restore power is covered by a sliding door.
- Sync port This port is used for plugging in an external sync cable. On most models of iPAQ this port can also be used to charge the iPAQ.
- Expansion port This port is the long port close to the back of the device. It is used to attach the iPAQ to its expansion sleeves. The H1910 does not have this port, as it does not support expansion sleeves.
- Soft reset switch Use this switch for soft resetting the system (no data is lost). This is like rebooting your computer. The switch is recessed and must be pressed with the tip of your stylus or other pointed object.
On the left side of the iPAQ you will find a single button. This button is intended for voice memos. When you press and hold it, you can record a voice memo that will be stored in the Notes area. Each press and hold will be stored as an audio file with the name “Recording X,” where the X is the next sequential number that doesn’t already exist in the directory. Note that on the H5450, this button can also be used to turn the volume up or down on playback of an audio file.
Finally, if you have a 54xx series iPAQ or an H1910, you have the option of removing your battery and replacing it with a spare. This is great if you are a heavy user and find you run through your battery quickly. A release button is on the back middle of the 54xx series units and on the right side (below the stylus) on the H1910.
Do not leave the battery out for long. Although these iPAQs contain a “backup battery” internally, it is only good for a few minutes, so switch your batteries quickly to prevent losing your valuable data and having to reinstall your programs!
