AF-3500 Series 46 mm displays are front-access only. This means that access to
the internal components is gained by removing the front modules of the display. Figure 22 shows the
approximate location of internal components.
6.1 Proper Ladder Use
A ladder can be used to access displays,
although it is not preferable. If a ladder
must be used, do not place the ladder
directly against the display face. The
pressure from the two ladder ends, even
when covered with pads, is too concentrated
and can damage the LEDs and louvers.
Instead, use a padded or carpeted board
across the top of the ladder to distribute the
weight of the ladder evenly when placed
against the display face. The padded board
should be wide enough to spread the weight
of the ladder across a minimum of two
modules.
