SET MODE = X
Select mode, where X is 1, 2, 3 or 4
To change mode proceed as follows:
•
ensure that the SEL switch in position 1 and that only DIL level 3 is down
•
rotate the ADJ control until the desired MODE number is displayed
•
the display brightness will flash until the setting is saved
•
move DIL level 1 down and up again to save the setting
•
the TANDEM unit will now reset itself and perform a power-up configuration
•
the new mode will be active once the configuration process is complete
In general it is recommended to select the mode required just after an initial power up.
Once the selected mode is active, load 'total defaults' and assign other required settings
such as audio group selection - see section 9.3 in User Manual for detailed operation.
There are special considerations for changes to and from mode 3.
Mode changes to and from Mode 3
•
unplug TANDEM, remove all sub-PCB cards
•
re-power TANDEM and change mode using Statesman or card-edge controls
•
wait until configuration has completed - display goes from 0% in 5% steps up
to 100% - then unplug TANDEM again
•
fit required sub-PCB cards to suit new mode
•
finally, load 'total defaults' if required (handled automatically from firmware
V5.15 onwards) - see section 9.3 for detailed manual operation
Note:
RS4 option cards are ONLY used for mode 3. Mode 4 requires ‘B’ issue option cards.
