Switch B-2: Time Base

Switch B-2 sets the controller's input voltage frequency at
either 50 Hz or 60 Hz. This setting must match the input
voltage frequency of your power source because the
controller senses this frequency as part of its internal timing
circuits.
Switch B-2 Off (default) – the controller operates at 60 Hz
Switch B-2 On – the controller operates at 50 Hz
Caution

Switch B-3: Page or Preset Access

Switch B-3 determines how the controller responds to the
Analog Inputs port as follows (for more information, see the
section titled "Remote Page Access" on page 6-16 and
"Remote Preset Access" on page 6-18).
Switch B-3 Off (default) – An attached analog controller
accesses the pages in memory.
Switch B-3 On – An attached analog controller selects the
controller's preset levels.

Switch B-4: Not Used

This switch is not used and should always be set OFF.
2-6 Setting the Switches
Selecting the incorrect time base
(frequency) will result in erratic program
playback. In general, the default setting
(60 Hz) is appropriate for North
American countries and the 50 Hz setting
is appropriate for European countries.
Consult a local authority if you are unsure
which time base setting to use.
