2.10 Mounting Preparation
1) Loosen the screws on the front cover of the

2) Move the SW1 RAM Storage Battery jumper
plug strap on the motherboard to the ON
position (Figure 4-5).

SW101 and SW201, to the PAD position to
provide a 3db level loss to avoid excessive
loudness.
4) Install all optional PCBs per Paragraph 5.
