Dimmer Operation
This section assumes the dimmer has been correctly connected to three phase power
and a source of DMX input signals as described in section 3.0.

Menu structure
The HP12-TR dimmers feature a “tree” menu structure. This means that an option is
chosen from the display with the
LEVEL/FUNCTION
encoder wheel, and the
ENTER
keypad button is then pressed to confirm the selection.
The encoder wheel is then used to select the next level of options, the
ENTER
button
is pressed to confirm the selection, and so on.
After all the options have been selected, the display reverts to
“OK”
to indicate the
dimmer is now back in normal operating mode.
The display will flash if there are more menu levels above the current one.
