The VFD is an active display showing 2 lines, each having a display width of 40
characters. It produces a blue light, the brightness of which can be controlled by the user.
It has greatly superior viewing characteristics as compared to a Liquid Crystal Display
(LCD), and does not suffer problems with viewing angle, contrast or temperature.
The keypad has six individual keyswitches. They have a positive 'click' action, which
provides the user with tactile feedback. As shown in Figure 4-1, versions of the CDM-Qx
manufactured prior to June 2007 feature a keypad mounted directly behind a fully sealed
membrane overlay. These six switches are identified (in Current Keypad [Earlier Keypad]
format) as ! [↑], " [↓], # [←], $ [→],
functions of these keys are described in the 'FRONT PANEL OPERATION' section.
There are eight LEDs on the front panel. The behavior of these LEDs is described in the
'FRONT PANEL OPERATION' section.
IMPORTANT
A USB Slave connector is provided on the front panel. This feature
allows the user to reflash firmware.
