Speaker
The speaker is located on the front of the mobile device above the Power button.
The Speaker has a loudness of at least 90 dB (2700 Hz) at 10 cm measured from the front of the
unit. The Speaker volume is adjustable via the keypad or the Control Panel or by an application
through the use of an API call. There are 16 distinct volume levels. The minimum volume level is
0 (no sound) with a default setting of maximum non-distorted volume. The volume sticks at
maximum and minimum levels.
The speaker is disabled when a headset is plugged into the Audio Jack on the endcap.
Speaker volume is enabled and adjusted using the Control Panel “Volume & Sounds” option.
After the speaker has been enabled using the Control Panel option, speaker volume is adjusted
using the 2
nd
+ <F8> key sequence, if desired.
Operational “beeps” are emitted from the speaker.
Infrared (IR) Port
Figure 2-10 Infrared Port – COM2 Port
At the back of the mobile device is an Infrared (IR) Data Port. The IR Port is designed to provide a
data link between the mobile device and a similarly equipped piece of equipment such as a printer.
The IR port is the mobile device’s COM 2 port and is a bi-directional half-duplex communication
port. It supports baud rates up to 115k, SIR (Slow IR). It will support serial port emulation, as well
as IrDA and Winsock over IR protocols. It also supports ActiveSync.
The IR operating envelope has a distance range of 2 cm (.79 inches) to 1 meter (3.2 feet) with a
viewing angle of 30 degrees.
The mobile device uses IrDA protocol to send data in both directions, but not simultaneously.
When sending data through the IR port, make sure the IR port on the first mobile device and the
IR port on the second mobile device are in close proximity to each other. IrDA is not required and
not used by terminal emulation programs.
