Pushbutton Lens Chip Installation
The primary crosspoint pushbuttons on the control panel are designed so lens
chips can be inserted to label the inputs assigned to each crosspoint. An envelope
containing a set of printed lens chips is shipped with the control panel. Make sure
not to throw away the lens chips inadvertently.
To install a lens chip, grasp the lens firmly with your fingers and pull it straight
out. The pushbutton may come off with the lens. You can then pull apart the
pushbutton, lens, and lens chip (refer to
pushbutton and lens into the panel, make sure to align the keys on the legs of the
pushbutton base with the larger key slots on the base of the switch (not the smaller
slots at the top of the switch, near the lamp). When properly installed, the
pushbutton should lock in place and not rotate around the lamp and switch. Two
lens designation strips are typically installed in crosspoint buttons using both
shifted and unshifted selection.
