Follow these instructions to properly install a ButterflyMX Windshield Tag on a vehicle.
Audience: Residents & Tenants
Windshield Tag
Size: 3.80 in W × 0.9 in L
Only one Windshield Tag should be installed per vehicle.
Install the Windshield Tag
Install the Windshield Tag:
- On the inside of the car, on the front windshield.
- Behind the central rear-view mirror.
- On the side of the windshield closest to the Vehicle Reader.
- Directly on the windshield glass, not on the upper cloth or plastic edge.
Tags are not meant to be transferred between cars or tenants. Attempting to transfer a tag may result in damage to the antenna and loss of adhesion.
Keep other vehicle tags away
Having multiple tags too close together on your vehicle may reduce read quality and prevent access to the gate.
Place the Tag as far away as possible from any other in-use tags, with a minimum distance of 2 feet. Remove any tags that are no longer in use.
Athermic windshields
Athermic windshields contain metal that can interfere with the Vehicle Reader and reduce the distance at which your tag can be read.
Most athermic windshields have a non-athermic section intended for radio-based systems, such as GPS or toll payment badges.
Even when the Tag is placed in this area, the read distance may be shorter than expected.
