The front panel buttons act as data transfer progress indicators. While data is being 
transferred, the buttons on both the transmitting and the receiving MLCs blink 
sequentially in clockwise order, starting with the On button in the upper-left corner 
(see figure 16). This cycle repeats until transfer is complete.

Figure 16.  Order in which the Buttons Blink during Data Transfer
After approximately 17 percent of the data has been transferred, the On button 
lights and remains lit to maximum brightness. After another 17 percent has been 
transferred, the Off button lights to maximum brightness also and remains lit. After 
each increment of 17 percent of the data has been transferred, the next button in 
clockwise order lights brightly. When a button becomes permanently lit, the remaining 
buttons continue to blink in clockwise rotation, until the transfer process is complete 
and all buttons are remain steadily lit.
The following table shows how each percentage of transferred data is indicated by 
button lighting.

When the transfer is complete, all buttons on each unit remain brightly lit until a button 
is pressed on the unit.
NOTE:  If the transmission is interrupted (for example, the two units become 
separated so that the IR LEDs are no longer in direct line of sight of each other) 
and the conditions necessary for transfer are subsequently restored, the two 
units restart the transfer process.
