on the Garmin screen.
• Once paired with the Trek CarBack, the Garmin will control when the light is on
and what mode it is in. Trek recommends Auto mode.
• The CarBack light has 2 settings for turning on and off. You can change this
setting on compatible Garmin computers.
• Option 1: When you power on your Garmin, your light on the CarBack turns
on. When you power off your Garmin, your CarBack light will power off.
• Option 2: When you press start for your timer, the light will turn on. When you
save your ride, the light will turn off.
Wahoo:
1. Make sure both the Wahoo computer and the Trek CarBack Radar are charged
and your computer is powered on.
2. Turn on the Carback with a 1 second hold. You are now in pairing mode.
3. Make sure your Trek CarBack Radar is within range (check your computer
manual for appropriate distance).

CarBack Radar
Owner’s manual
About this product
The CarBack is a Bluetooth & ANT+ compatible radar system with an integrated light to help
increase a rider’s situational awareness on the road. The radar can communicate with select
bike computers and smartphones. For detailed instructions on setting up your device, please
refer to the user manual provided by the respective brand’s bike computer.
• Do not use if the battery is impacted. Also do not puncture, crush, deform,
disassemble, or heat a lithium-ion battery above 140° F (60° C). Damage to the battery
may result in a fire, explosion, and/or exposure to specks of lithium or lithium dust.
• The light is very bright. Do not stare at an operating light. Staring may be
harmful to the eyes.
• Proper use of the device can enhance your riding experience, but improper
use can lead to distractions and severe injury or even death. Exercise caution
and use the device appropriately and attentively.
• Proper use: Quickly check the radar device information while maintaining focus
on your surroundings (when making turns, passing, changing lanes, etc.). Avoid
prolonged staring or getting distracted by the device’s display.
• Improper use: Overly focusing on the display may cause you to overlook
obstacles or dangers, putting you at risk of serious consequences.
WARNINGS:
A bicycle without correct lights and reflectors might be difficult for other people to
see, and you might not be able to see them. If you cannot see, or other people
cannot see you, you could have an accident. Make sure your lights are set up,
operating correctly, and that batteries are charged.

IMPORTANT: Check your local lighting laws. Flashing lights and full brightness may not be allowed in
all locations. The CarBack radar light does not conform to the German road traffic regulation StVZO.
Reset
To reset the CarBack to factory default settings:
• With the CarBack on, press and hold the power button for 15 seconds.
The main LED will flash once at 8 seconds and again at 15 seconds.
• Release the button after the second flash.
• Once reset, the wireless broadcast will be disabled until the first time the CarBack is powered on.
Charging the battery
The CarBack was charged prior to packaging, but we recommend you charge it before first use.
IMPORTANT: For best results, charge at room temperature in a dry place. Use an approved
(ex. UL certified) USB-C charger rated for 500mA or greater. Avoid extreme conditions including
wet, cold, or extreme heat.
1. Open the USB port cover.
2. Plug the USB-C charger cable into the USB port on the unit.
3. Plug the cable into a computer or wall adapter.
4. When all lights are off, the charge is complete. Unplug the charger cable and close
the USB port cover.
5. If you charge your computer at the same time as your CarBack it may keep your
CarBack on after unplugging. When unplugging the CarBack after charging, turn
the CarBack off if the fuel gauge is still on. Press and hold the power button for 1
second to power down.
IMPORTANT: Ensure the USB cover is latched before riding in rain or wet conditions. If the USB
cover is not closed, damage to the unit may occur. Do not leave the unit outdoors when not in use.
NOTE: If the main button indicator is flashing red while plugged in, the light is either too hot or
too cold to charge. Charging will begin when the light is between 32˚F (0˚C) and 104˚F (40˚C).

If the bike computer is disconnected from the CarBack, the radar and light may stay on which
may deplete the battery. For example this may happen if the bike computer is removed from the
bicycle and taken away from the CarBack. The fuel gauge lights will remain on anytime the radar is
active (on). The CarBack unit will automatically turn on/off when it has been previously paired with a
compatible bike computer.
NOTE:
To operate correctly, the unit must:
• Be between 70-120cm
(27.5-47in) from the ground,
• Point straight backwards
(up/down, left/right),
• Not be blocked by your wheel,
saddle bag, fender, etc.

With the CarBack paired to your bike computer
There are various factors that will obstruct the performance of the device, resulting in
reduced efficiency and effectiveness. Riders directly behind you and mud or ice on the
device may block the radar. Hilly or curvy roads may give you intermittent signals, and
vehicles driving at the same speed right behind you may be less recognizable. Failure
.to understand and be aware of these factors can lead to serious injury or death
WARNING:
See also the CarBack supplement for more instructions.
First time use
Turn the CarBack on and pair it to your smartphone or compatible bike computer.
The process will vary between smartphones and bike computers, but typically:
1. Search for new sensor.
2. Pair sensor/radar.
NOTE: Most bike computers will recognize the device as both a light and a radar. Check your
bike computer. It may be set up to automatically power up and power down the light network
when you start/stop your ride or start/stop/pause your timer.
Basic operation
Download the Trek mobile app and follow the prompts to connect with the CarBack.

CarBack battery charging and care
Low battery mode
At 5% battery life, the display indicator will flash red. The radar does not operate in this low battery
mode but the light will continue to operate.
Recycling
Please recycle the CarBack with the battery. In the US you can find out where to do this at
www.call2recycle.org.
If you or someone you are riding with has photosensitivity to flashing lights, ensure
this light does not trigger an episode prior to use on the road. While the flash
pattern is designed to be outside of the frequency range most associated with
causing a photosensitive reaction (5-60Hz), each individual’s response may vary,
and having an episode while riding may result in serious injury or death.
WARNING:
Caring for the battery
• Store the CarBack at room temperature in a dry place. Avoid moisture, or extreme hot or cold.
• Store the CarBack in a charged condition. Battery life will decrease if the battery is stored in
a fully discharged condition.
• Over time, the runtime of the battery will diminish. Expect about 500 full charges, depending
on care. After a full life, the battery will continue to charge but with a lower runtime. When the
runtime is unsatisfactory, do not open the case of the light or incinerate; please recycle.
Traveling with the battery
Make sure the CarBack is turned off during travel. When traveling by air, verify with your carrier
how lithium ion batteries of this capacity must be treated. Often these devices need to be packed
in carry-on luggage.
Protection
The CarBack has been designed and tested for use in all riding conditions and has an ingress rating
of IPX7. The CarBack is not intended to be stored outdoors and should be stored and charged
indoors after use.
