Through-Glass Button Tips and Troubleshooting
The Through-Glass Buttons are designed to filter normal levels of ambient interference and to protect
against false triggering, however it is recommended that the Through-Glass Buttons be turned off (slide
THRU-GLASS BUTTONS switch to OFF) if there is an infrared interference source in line-of-sight to the
display or if the buttons are not needed.
Through-Glass Button Tips:
To the extent possible, install the display facing away from sunlight, windows, reflective objects and
any sources of infrared interference.
Keep the glass window clean.
Tighten the cover securely.
Use a password to prevent tampering.
If the cover has not been installed and secured tightly, it may take a moment for the Through-Glass
buttons to properly self calibrate when the cover is tightened.
After all connections have been completed and verified, connect the ribbon cable to the display module,
fasten the display module to the base, install enclosure cover, and then apply power.
Through-Glass Button Equalize Delay
The Through-Glass buttons are designed to constantly recalibrate for ambient
conditions. When the cover position is changed, the cover is removed, or an
object is removed that was placed over the front window, it may take a moment
for the Through-Glass buttons to recalibrate to the change in conditions.
Allow up to 2 minutes for the Through-Glass buttons to recalibrate to new
conditions in these cases where the cover position was changed, or the front
window is being unblocked.
