displays the DMX start code. Packets with a start code other than 0 may cause irregular
performance.
The remaining readouts under

display the DMX values received on each of the 13 channels
available in both 16-bit and 16-bit Extended modes, from

(shutter, channel 1) to

(effect
speed, channel 13). If the fixture does not behave as expected, reading the DMX values can help you
troubleshoot the problem.

The manual control menu (

) provides commands for resetting the fixture (

), as well as striking the
lamp (

), and dousing the lamp (

). It also permits you to position and move individual effects.

The test sequence (
 → 
) runs through all effects to provide a quick check of fixture performance.
Press [Menu] to stop the test.

Note that [Enter] must be pressed for 3 seconds to access settings in the

menu.
Sensors monitor the positions of the pan/tilt systems and color wheel. If they detect an error, the effect
resets on the fly. The shutter closes during resetting.
To ease service, for example, this feature can be disabled for pan/tilt by turning pan/tilt feedback off
(



→

). The disabled pan/tilt feedback setting is saved when you exit the

→

menu.
Color wheel feedback can also be turned off (



→

). This setting is also saved when you
exit the

→

menu.

The adjustment menu (
 → 
) provides commands for positioning the head and effects, as well as
an effects position test sequence, during service and mechanical adjustment (see “ Adjustment submenu ”
on page 32).
If the test sequence is run by selecting

and an error is detected, the test
aborts and a number flashes in the display to indicate which effect is out of position. Note this number and
contact your Martin service center for advice.

With the calibration menu (

→

), effect positions can be fine-tuned with a software-defined offset
value to compensate for small misalignments or differences between fixtures.
The default offset command (
