* A 2-channel external pump is provided in the upgrade kit. This pump is
significantly faster than the autosampler's built-in pump.
** When used in conjunction with the external pump, the speed of the internal
pump must be increased to its maximum setting. This requires setting a jumper
inside the autosampler.
Other Setup Tasks
This chapter also includes a summary of the instructions for upgrading the
autosampler firmware, if that should become necessary.
Several optional tasks require opening up the autosampler:
 Upgrading the autosampler firmware
 Adjusting the speed of the built-in peristaltic pump (if you will be using the
external 3-channel peristaltic pump)
