Accessing System Information
A number of hidden screens and undocumented information codes are available on your BlackBerry device. The key is to know how to access them. This section describes a few system-level screens that can be useful or, at the very least, interesting to take a look at.
The Help Me! Screen
The Help Me! screen is useful because it gathers key information about your device. It displays your operating system version, battery level, wireless signal strength, and available storage.
To access the Help Me! screen:
-
Go to the Applications screen and press ALT+CAP+H.
-
To close the screen, choose the Close menu or press the back button.
The Event Log
The Event Log offers a view into system events that occur on your BlackBerry. It can also be a useful debugging tool to track down what might be going wrong with an application or service on your BlackBerry.
To access the Event Log:
-
Go to the home Applications screen and hold down the ALT key while entering the key sequence LGLG. After a second or two, the event log appears (see Figure 1-2).
Within the Event Log, you can click on the trackwheel to view more details about a given event, clear the log to reclaim some storage memory, or go into the Options menu to fine-tune the types of events that are logged.
-
To close the Event Log and return to your home screen, choose the Close menu.

The Signal Strength Display Mode
The standard signal strength display on a BlackBerry uses the familiar "five bars" graphic — the more bars you have, the better your signal strength (as shown in Figure 1-1). If you prefer more precision, however, you can have the signal strength display in actual numbers (see Figure 1-3).

To change your signal strength display:
-
Go to the home Applications screen and hold down the ALT key while entering the key sequence NMLL.
-
To return to the standard graphical bar display, enter the same key sequence, ALT+NMLL.
The numeric signal display represents your signal strength in decibels (dB).
Smart System Codes
You can obtain various types of information about your system by using smart system codes (see Table 1-2). Simply enter the code into any input field, and then press the Enter (or space) key.
