Component Descriptions
Safety Lid
The transparent safety lid must be closed in order for voltage to
be applied to the electrodes. Interlocks are used to stop the voltage
output should the lid be opened during electrophoresis.
Knob
The knob moves the cursor or changes the values of a given field.
Pressing the knob inwards to “click” switches between these two
functions. A LED indicates which function is active, MOVE or SET.
Horizontal Arrow Keys
The horizontal arrows are used when setting protocol names, and the
date and time fields.
High Volt Indicator LED
This LED is lit when voltage is being applied to the electrodes.

Note: Turn the knob slowly to get
desired movement on the screen.
Turning the knob too fast causes the
cursor to blink, and stay in place. If this
happens, turn the knob slower until the
proper behavior is observed.
Note: The click action of the knob is to
quickly push and release, like a mouse
click. Do not hold the knob in.
