The syntax for setting a special function for an MLC is

X?

* __ # where

X?

is the

value and __ is the function number. To view a function’s setting, use __#,
where __ is the function number. In the following table the values of the

X?

variable are different for each command/function. These values are given in the
rightmost column.

Delay times

Most projectors require a certain amount of time during warm-up and cool-down during which they do not accept
commands. Once you have set the input selection lock during power on/off command (53#, page 5-39), send this
command (1#) to specify the amount of time for the MLC to wait between sending the projector a power-on or power-
off command and when the next input button press can occur.

0 = 0 seconds,

VolLimit*

X? ]

If this feature is enabled, the
maximum initial power-up
volume level does not exceed the
level specifi ed by this command.
0 = audio off, ...,
20 = default value, ...,
100 = no limit on audio level at
power-on.

N The MLC responds with an E14 error code when volume mode = 1 (increment/decrement).

N The maximum is limited by the maximum volume setting (47#). If the maximum volume (47# command) is set, the

limit audio level feature (11# command) is automatically set to 25% of the maximum volume (47#). See page 5-39.

Example:

28*11#

VolLimit*028

]

Example: limit power-up volume
to 28% of maximum volume.
