7.10 Final Reassembly
Important
You must refit the correct type of front panel to your
TB9100 base station. There are several small but important
differences between the front panel for a 5 W or 50 W base
station and the front panel for a 100W base station. These
differences are in the duct for the PA fan and are described
in the following paragraphs.
5W or 50W Front
Panel
The PA fan duct does not have the cut-outs
b
required for the 100 W PA
RF and DC cables. The break-off tab
c
will also still be present and will
jam on the system control bus. Do not try to fit this front panel to a 100W
base station or you will damage these cables and possibly the front panel
itself.
100W Front Panel
Do not fit this front panel to a 5W or 50W base station. The presence of
the cut-outs and absence of the break-off tab will allow air to escape and
reduce the velocity of air directed through the heatsink.
