UL/Safety Requirements
The Underwriters Laboratories (UL) requirements listed below pertain to the safe
installation and operation of a MediaLink ® Controller (MLC).
1. Do not use the MLC near water or expose it to liquids.
W To reduce the risk of fire or electric shock, do not expose this apparatus to
rain or moisture.
2. Clean the MLC only with a dry cloth.
3. Do not install the MLC near any heat source, such as a radiator, heat register,
stove, or another apparatus (including amplifiers) that produces heat.
4. Unplug the MLC during lightning and thunderstorms or when it will be
unused for long periods.
5. For the installation to meet UL requirements and to comply with National
Electrical Code (NEC), the MLC must be installed in a UL approved junction
box. The end user or installer must furnish the junction box; it is not included
with the MLC.
Installing or Replacing Button Labels
For the MLC or the optional SCP control panel, you may wish to customize the
button labels. The labels can be changed at any time. You can use printed labels
included with the unit, write on blank labels, or purchase additional sheets of
printed button labels from Extron. Button caps are also available, should you need
to replace one.
Button labeling procedure
Follow these steps to change the translucent button labels:
1. Remove the button from the MLC or SCP; use a small, flat bladed screwdriver
such as an Extron Tweeker to gently pry a button out from the front panel.
2. Locate the notch in the corner of one side of the clear
button cap lens.
3. Separate the white backing (diffuser)
from the clear button cap (lens);
insert the blade of the small
screwdriver into the
corner notch and gently
twist the blade.
4. Save the translucent,
white diffuser, but
remove the text/
label insert from the
transparent button cap
lens.
5. Select one of the button
labels from the printed label sheets
included with the device (MLC or
SCP). Remove the label from its backing, if
applicable.
6. Insert the button label into the button cap. Check for correct label orientation.
7. Align the white diffuser plate with the cap (lens). The bumps on the diffuser
plate should be aligned (top and bottom) with the notches on the clear button
cap. Firmly snap it into place.
