To have Device Central automatically connect to the online library, go to General Preferences.

The default phone ID is the International Mobile Equipment Identity (IMEI) number of the device that Device Central is emulating. Each Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) mobile device has a unique IMEI number. The 15‑digit number identifies the origin, model, and serial number of the mobile device.

Specifying a default phone ID instructs Device Central to use that number as the default IMEI for any device tested.

1. Select Edit (Windows) or Device Central (Mac OS) and then Preferences and General.

2. Enter a new number in the Default Phone ID text field.

Use the Undo Levels option to change the number of times you can revert to a previous state. For example, the default setting of 20 enables you to revert through your last 20 actions.

1. After accessing Preferences, select General from the list.

2. Enter a new number in the Undo Levels text field.

Depending on the language packs installed, you can change the language for Device Central to British or American English, French, German, Japanese, Spanish, Italian, Dutch, Swedish, Korean, Chinese Traditional, or Chinese Simplified. After you restart Device Central, the user interface contains text in your selected language.

1. After accessing Preferences, select General from the list.

2. Select a language from the Application Language menu.

Use the font mapping option to define the device fonts used when emulating a device. In a FLA file, you can specify generic device fonts, such as sans, serif, or typewriter. Adobe Flash Lite™ automatically tries to match the selected generic font to an available font on the device at run time. If you know the device fonts available on a device, you can select those fonts or similar ones from the Assigned Fonts lists.

1. After accessing Preferences, select Font Mapping from the list.

2. Select a language from the Language menu.

3. Select sans, serif, and typewriter fonts from the menus.

The Log and Output preferences include several settings. They are all optional; use the ones you want. By default, the snapshot pool size is 500 MB. When you quit Device Central, snapshots are removed from the log window. However, they still take space in the pool, unless you clear them.

1. For Max. Pool Size, enter a value.

   The minimum is 5 MB. If 90% of the space is filled, a low disk space alert is displayed in the log window.

2. Select Automatically Clear Snapshot Pool When Quitting Device Central.

3. Select the Clear Pool Now button.

4. Enter a value for the Maximum Number Of Snapshots Per Session.

5. Select Automatically Clear Flash Output Window When Reloading SWF.

   The images stored during a previous session are not affected.
