Options for selecting sounds have a button with a speaker symbol. To listen to sounds, use the slider to Enable Audio
Playback or press the icon next to the sound you wish to hear. For safety, the unit will need to go into Maintenance Mode
and the LED will perform a three-flash pattern. Press Yes on the confirmation dialog to enable Maintenance Mode. In this
mode, the unit’s main button will not operate or respond to interval changes so a pedestrian cannot use it. This will only be
done on the iNS unit you are directly connected to, so a remote button cannot be made to play a walk sound and confuse
a pedestrian.
Tap the speaker symbol to listen to the selected sound. Sounds will play
out of the PBS’s speaker. Turn off the Enable
Audio Playback switch to resume the unit’s normal operation.
When you are finished selecting desired settings, tap the Write button to write the settings to the selected button.
Alternatively, tap the menu symbol at the top right to access additional options including saving to all buttons in the
intersection. After saving new settings to buttons, walk the entire intersection to test each PBS for proper operation to
verify that the new settings work as intended.
