When the E2024 AUTO – MUTE – START switch is set to MUTE or START (i.e. manual control), the 
display  shows  the  actual  switch  setting  and  the  manual  setting  of  high/low  power  (‘Manual=’).  The 
latter can only be done by an internal link (i.e. this setting of high/low power cannot be done from the 
front  panel).  In  this  mode,  the  switch  mute/start  selection  can  only  be  over-ridden  by  the  safety 
interlock  opening  and  muting  the  Transmitter  directly  (the  first  part  of  the  display  then  showing 
‘Manual=I-Lock’). The automatic settings are displayed as ‘Auto=’ and can be set as described in the 
previous paragraph. 
 
When  the  E2024  AUTO  –  MUTE  –  START  switch  is  set  to  AUTO,  the  display  shows  the  automatic 
settings  in  operation.  As  before,  the  mute/start  selection  can  be  over-ridden  by  the  safety  interlock 
opening  and  muting  the  Transmitter  directly  (the  first  part  of  the  display  then  showing  ‘I-Lock’). 
However, auto operation also allows the internal auto mute/start setting to be over-ridden by the rear 
panel ‘Mute Transmitter Input’ (see section 2.2.8) the first part of the display then showing ‘(ext)Mute’. 
 
The order of priority  is thus ‘I-Lock’ then ‘(ext)Mute’ then ‘Start/Mute’  as selected internally. When ‘I-
Lock’  or  ‘(ext)Mute’  are  operative,  the  START/MUTE  soft-keys  are  disabled,  being  shown  as  ‘(x)’, 
though this selection can still be made using remote control. 
 
Similarly  with  the  E2024  AUTO  –  MUTE  –  START  switch  set  to  AUTO,  the  internal  high/low  power 
setting can be over-ridden by the rear panel ‘Select Low Power Input’ (see section 2.2.8) the second 
part  of  the  display  showing  ‘Low(ext)’.  The  order  of  priority  is  thus  ‘Low(ext)’  then  ‘High/Low’  as 
selected internally. When ‘Low(ext)’ is operative, the HIGH/LOW soft-keys are disabled, being shown 
as ‘(x)’, though this selection can again still be made using remote control.  
 
It should be noted that auto mode has to be selected by the E2024 AUTO – MUTE – START switch to 
enable low power to be selected remotely or via the front panel. The only manual mode provision for 
selecting low power is via an internal link, which then over-rides all other auto settings that might be 
made. 
 
To display the output power again, press [MAIN] as previously described.
