PUSH BUTTONS
Two push buttons are provided on the front of the unit for user input. One button is labeled
with an UP ARROW and the other with a DOWN ARROW. When the buttons are pressed,
an audible beep will occur. The keys also have tactile feedback when they are depressed.
Using the buttons to set all of the parameters of the unit is accomplished via single and
double key presses.
Single key presses are accomplished by briefly pressing and releasing an UP ARROW or
DOWN ARROW button. If a single button is pressed and held for 2 seconds, the setting
will increase or decrease rapidly depending on the button pressed. For example, in the
default display, briefly pressing and releasing the UP ARROW will increase the set point
temperature by 1C with each press. If the UP ARROW is pressed and held down, the set
point will increase by 1C after the first press but after holding for 2sec the set point
temperature will rapidly increase until the button is released or until the maximum set point
for the unit is reached.
A double key press is accomplished by simultaneously pressing and releasing both UP and
DOWN ARROW buttons. In the default display, briefly pressing and releasing both arrows
will toggle the cursor between the Set Point selection and the Orbital Speed selection.
When the cursor is at the Set Point selection, use the UP and DOWN single key press to
set the Set Point and likewise for the Orbital Speed(see Figure1). Pressing and holding
both buttons simultaneously will bring up the Menu on the LCD display. Scrolling to the
various options in the Menu is accomplished by pressing the UP and DOWN ARROW
buttons. This manual contains details on accessing and setting the various Menu options.
