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.
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 thunder storms 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. 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.
3. Separate the white backing from
the clear button cap; insert the
blade of the small screwdriver into
the corner notch and gently twist
the blade.
4. Save the translucent, white
backing plate, but remove the
text/label insert from the
transparent button cap.
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 backing plate with the cap. The bumps on the backing plate
should be aligned (top and bottom) with the notches on the clear button cap.
Firmly snap it into place.
8. Align the tabs on the MLC with the notches on the backing plate. Gently but
firmly press the reassembled button into place in the MLC’s or SCP’s front
panel.
9. Repeat steps 1 to 8 as needed to relabel other buttons.
