IR Port

The InfraRed (IR) port provides a means of transferring information to a device
with a similar port and the proper software. The IR port can be used to
communicate with printers or a host computer with the use of an adapter.
The IR Port is specified as COM 3 and is a bi-directional half-duplex infrared port.
It supports the Slow IrDA (Infrared Data Access) PHY Layer standard that allows
communication speeds up to 115k baud.
When sending data through the IR port to another MX5's IR port, make sure
both units are in close proximity to each other. The IR operating envelope has a
distance range of 2 cm (.79 inches) to 15 centimeters (6 inches) with a viewing
angle of 30 degrees.
See the "MX5 Reference Guide" for complete instructions.

left side of the key) or blue (on the right side of the key), that represent the 2nd
function of that key. Using the 2nd key activates the second key function. Note
that the 2nd key only stays active for one keystroke. Each time you need to use
the 2nd function you must press the Orange or Blue 2nd key. To cancel a 2nd
function before pressing another key, press the 2nd key again.
Ctrl Key Function
The Ctrl key enables the control functions of the keypad. This function is similar
