Figure 5.11: [US only] Virtual Key Functions for Normal Sets in PABX Mode
5.1.2 8028 Premium DeskPhone, 8029 Premium DeskPhone sets
Each  of  these  sets  has  2  programmable  keys  (F1/F2)  and  40  virtual  add-on  keys.  Their  default
functions depend on:
• The configuration of the set (Operator, Manager, Assistant, Normal or Attendant)
• The market in which the set is sold (US or non-US)
• The operating mode of the set (KeySystem or PABX mode)
The default functions of these keys are the same as for the sets detailed in 8038 Premium DeskPhone,
8039 Premium DeskPhone and 8068 Premium  DeskPhone  sets  on  page  156.  However, in this case
the virtual  keys  are  selected  using  4  physical  buttons,  2  on  each  side  of  the  set's  display,  as  shown
below.
