FEATURES
POWERING ON
Wireless Parking Sensor:1.
Wireless parking sensor utilizes Bluetooth 4.1 technology to send
instant audio, visual, and vibration alerts to your phone.
Auto-launch:2.
Tap the included launcher button to launch the Android app instantly
(when phone screen is unlocked) or receive a push notification (iOS)
to launch your Apple app.
Universal Battery:3.
Enjoy 5 month battery life with average use. Batteries can be replaced
with standard universal AA batteries.
Easy Install:4.
Installs in 5 minutes with included custom security screws to
prevent theft.
Portability:5.
Bring your FenSens with you to your next vehicle purchase or hand
it down to your next of kin.
Hands-free alerts:6.
Mount your phone with the included phone mount and utilize audio
alerts or the visual display to assist you with parking. Turn on your
vibration settings to utilize vibration alerts if your phone is in
your pocket.
Place the batteries in the device and it will turn on. Afterwards, the device
will continue to sit in low power mode thereafter and you will not be
required to turn the device on again. After turning on the device, please
download the app in the app store (iOS and Android only) and follow
the setup instructions. Note: You may have to remove the batteries and
place in the device again to reset the device.

08
SETTING UP THE MOBILE APP
Download the app on the Google Play or Apple iTunes App Store
Select whether the device will be mounted on the front or back of your
vehicle. Select only one option for now, but you can choose a second
device to the front or back after the initial setup process.
Adjust the clearance for your device, especially if it is placed on your
back license plate. This is to compensate for the bumper or hitch
possibly sticking out past the position of the sensors.
Make sure your smartphone Bluetooth settings are turned on, then pair
your smartphone with the FenSens device and the QuickLaunch button.
Launch FenSens anytime you want to use it by simply opening the app,
hitting the sensor icon within the app’s navigation bar, or tapping the
included QuickLaunch button.

MOUNTING DEVICE
Place included batteries within the smart parking sensor device, then
seal it up with the provided screw set. Open up the QuickLaunch button
and remove the protective plastic strip between the battery and the
battery connector.
It is best to setup the mobile app and pair it with the device before
installing on the vehicle.
After setting up the app, place the smart wireless license plate frame
on top of your front or back license plate over the corresponding
screw holes.

09
Use the included custom screwdriver to screw in the smart wireless
license plate frame. It’s important to use the custom security screws
included with your kit as these screws will help prevent people from
stealing your device. Fully tighten the screws so the device is secure.
Make sure your registration tabs and plate numbers are fully visible in
order to stay legally compliant. Please refer to local rules and
regulations regarding license plate visibility.
Wiggle your device to ensure it is fully screwed in and secure.

The sensors can be adjusted up or down if you need them to be. We
recommend this if your plate is higher than 3 feet off the ground or you
are concerned about catching low hanging objects, such as curbs. Please
adjust the sensors to a position you are comfortable with using the flat
ground as a reference. You do not want the sensors to be hitting the road
and providing false readings.
The screw holes can be identified in the image below. Be sure to use the
special tool that’s included with your kit to unscrew and adjust the sensors
up or down. Tighten the special sensor screws after making an adjustment
so they do not change position while in use on your vehicle.
ADJUSTING SENSOR POSITION

Please note: FenSens is not recommended for vehicles with a license plate
higher than 4 feet off the ground. The higher your smart wireless license
plate is placed off of the ground, the more clearance you need to set within
the app. Please see feature 12 in the Features section along with the
diagram below.

Please note: the mobile app display is for visual purposes only and does
not represent exact dimensions for the Smart License Plate Frame.
Always use precaution when driving, checking for blind spots while
operating or parking your vehicle.
BACKING UP SAFELY
FenSens is best used for backing up or pulling forward into a parking spot.
Please visually check the spot before making a parking maneuver.
Listen for audio alerts from your phone if something should suddenly
appear in front or behind your vehicle (depending on sensor placement).
You will only receive sensor alerts from the side of your vehicle that the
device is mounted on.
If the device ever disconnects from your
smartphone’s Bluetooth, you will
receive a pop-up notification and an
audio alert to your smartphone.
Please pay attention to this warning and
proceed with caution or halt the
parking maneuver. The warning will
disappear as soon as the sensor
reestablishes a connection with your
smartphone.

Refer to the diagrams below before using FenSens so that you can fully
understand the field of vision for the device. Please note that the corners
of the bumper are not covered and the field of vision is best used for
objects directly in front or behind the vehicle, which can be seen best by
moving your vehicle forward or backward in a straight line.

Warning: Performing a factory reset on the FenSens device will delete any
previous pairings and will restore the device to factory default settings.

FenSens device. You can share access to the device from your
app profile settings.
Only perform this if you are experiencing any issues with the product.
Note: After the factory reset is complete, the memory is now cleared.

them back into the license plate frame. This will factory reset
the device, but it will still be registered to you.
