2.1 REMOVING THE INSTRUMENT FROM ITS HOUSING
To withdraw the instrument from its housing, simply grip the side edges of the front
panel (there is a finger grip on each edge) and pull the instrument forwards. This will
release the instrument from its rear connectors in the housing and will give access to
the PCBs. Take note of the orientation of the instrument for subsequent replacement
into the housing.The positions of the PCBs in the instrument are shown in Figure 2-1.
