Speaker
The
speaker
is located on the front of the MX3Plus 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 control panel.
After the speaker has been enabled using the Control Panel option, speaker volume is adjusted using the 2nd + <F8> key
sequence, if desired. Operational "beeps" are emitted from the speaker.
IR port
At the back of the MX3Plus 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 MX3Plus'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 MX3Plus 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.
When the MX3Plus is docked in a cradle, the Status LED on the cradle is red when data is being transmitted through the IR
port.
