A1 Front Panel Assembly Replacement
The A1 assembly comes in two different versions for both the ET and ES models: 50Ω and
75Ω. However, the difference is only cosmetic. Both assemblies have all the front panel
components including frame, keyboard, keypad, and knob. The assemblies do not include
the model number nameplate, which must be ordered separately, nor do they include the
type-N connectors which are part of the A5 receiver assembly.
If the front frame has been damaged, but the keypad and knob are acceptable, you can
save money by ordering only the following three parts (refer toTable 7-3on page7-5):
•front frame
•nameplate (choose according to model number)
•front plastic dress panel (choose 50Ω or 75Ω version)
CAUTION Perform the following proceduresonly at an approved ESD workstation. See
Figure 4-1on page4-3.
