Operation
Using the Control Panel
The control panel (see figure 2-2) includes: a display screen, cursor keys, a numeric keypad
with enter key, and a touch pad with left and right “mouse” buttons.
Display Screen
• The display screen is a 1/4 size VGA screen for displaying thermal cycler conditions
and programs.
Display screen contrast adjustment
Underneath the front lip of the Dyad cycler, positioned below the cursor buttons,
there is a small, partially recessed knob (see figure 2-4). This knob can be rotated to
optimize the contrast of the color display.
Operation Keys
• Cursor keys (left, right, up and down arrows): Use to move around within the
display screen.
• Numeric keypad: Use to enter numeric values.
• Enter key (below keypad): Use to accept specific programming additions and
modifications.
• Touch pad: Use to move the display screen pointer with the movement of a finger tip.
Once the pointer is positioned over a menu or selection item on the display screen, a
single or double tap of the touch pad with a fingertip will implement the command. A tap
on the touch pad corresponds to clicking the left button on a mouse.
• ‘Mouse’ buttons (left and right buttons below touch pad): Pressing the left
button is identical to a single tap on the touch pad or clicking the left button of a mouse.
The right button has no current function.
