GL2800 User Guide 37
User Options
The GL2800 has a versatile architecture which should satisfy most
applications you may encounter without modification. However, the following
internal options provide alternative settings for those applications that may
demand them. Access is required to the internal assemblies. For user
convenience, pluggable jumper links are used in most places.
Do not adjust the user options while power is applied to the console.
Do not remove or tamper with the internal power unit, its cover or wiring.
Remove the base Switch off power and unplug the power unit and all the
cables. Invert the console on a flat, clean, well lit surface. Use Torx (star head)
screwdrivers to remove the screws holding the base to the chassis. Use a T15
driver to remove the set of 6Bx5/16 screws holding the base to the rear and
underside of the chassis. Carefully lift off the base.
Configure the internal options Fit any options required referring to the
instructions provided. Set the option jumpers to the required positions. Make
sure they are pressed fully home. Check that all channels are correctly set and
all options fitted according to their instructions. Make sure that no debris or parts
are left loose inside the console.
Refit the base Carefully reposition the base. Refit the fixing screws.
IMPORTANT: Check carefully that all channel jumpers are correctly set
as required. Errors on one or more channels now may cause user problems
later. We recommend that you write the repositioned jumper settings on a label
and adhere this to the rear panel. This would provide a helpful reference to other
users of the console.
