Ampere Dusk User manual



How many times have you left your house without a pair of sunglasses because it’s not sunny
enough…only to have the clouds magically disappear minutes later, and you’re left squinting
your way through your walk/run/drive?
Now that you have Dusk, you will always have the perfect sunglasses for every situation.
Dusk are the first sunglasses in the world that allow you to choose the exact tint level you want.
Not every day is the same, why should your sunglasses stay the same?
The functionality doesn’t end there. Dusk has open-ear audio speakers built into the arms so
you can listen to podcasts and music while staying aware of your surroundings. And built-in
microphones allow hands-free access to phone calls and voice assistants. On top of all that,
you get glasses made with premium materials and lenses that look flat-out great.
Before using the sunglasses, please read all instructions, safety information, and warnings. And
make sure to download the Ampere app to get the most out of your Dusk.
Thank you for your support! We’d love to hear what you think about Dusk. Please email us with
any questions, concerns, feedback, etc. at hello@amperetech.co.
Thanks!

Before using, charge Dusk
using the included USB-C

take about one hour.
The LED indicator will turn
red when Dusk is charging

and the LED will blink red
and green.
Hold the “Left Arm

functionality.
Enable the Bluetooth settings on
your chosen device and select
“Dusk”. Once paired, the LED
indicator will stop blinking and
the “paired” sound will play.
In order to use the app-enabled
tint adjustment, your device
needs to be paired to Dusk via
Bluetooth and tint adjusting
functionality needs to be
activated.
Now your Dusk is ready for use!

Dusk is designed with silicone nose pads for a comfortable fit and to prevent Dusk from
sliding down your nose. If you would like a narrower nose bridge, you can replace the
nose pads with a thicker nose pad.
Switching nose pads is a permanent adjustment.
The entire length of the arms of Dusk have electronics built-in. Do not bend them
in any way to adjust the fit.

The button on the right-hand side, when you are
wearing Dusk, is used to control the Bluetooth and
audio functionality. Audio and app tint adjustment
both require Bluetooth pairing.
Power On: Hold for 3 seconds. A green LED will
illuminate for 3 seconds and the “power on” sound

illuminate for 3 seconds and the “power off” sound

Pairing: When Dusk is powered on, it will
automatically go into Bluetooth pairing mode.
Pairing mode will last for one minute. If no device
is paired within one minute, Dusk will automatically
turn off. While Dusk is in pairing mode, the “pairing
sound” will play and the LED will flash red and
green. If you want to turn off the Bluetooth pairing
sound, press the button once to mute.

The button on the left-hand side when you are wearing
Dusk, is dedicated to lens tint level adjustment. In order
to use the tint adjusting functionality, it must first be
activated. Dusk tint adjustment is designed to use
minimal power so, once activated it can remain active
without substantially affecting the battery level. After 4
hours without activity, Dusk will enter “low power mode”
and revert to the lightest tint level to save battery.
If you are adjusting the tint level using the left arm
button, Dusk does not need to be paired to your device
via Bluetooth. If you would like to adjust the tint level
using the Ampere App, your device needs to be paired
to Dusk via Bluetooth and tint adjusting functionality
needs to be activated.
Activate Tint Level Adjustment: Hold for 3 seconds.
Deactivate Tint Level Adjustment: Hold for 3 seconds. *Tip — If you find that that the tint level is not
adjusting, try resetting by holding the left arm
button for 3 seconds.

Use the Ampere app to
choose the exact tint
level and darker tint levels
(up to 4% transmittance).

Dusk comes with a USB-C to magnetic pogo pin
charging cable. Only use the charging cable with certified
power supplies, chargers, and batteries that are made by
reputable suppliers. When using the charging cable and
an adapter, do not leave Dusk plugged in for more than 12
hours — as it will continue to “trickle charge” and over
time, this may affect battery life. The Dusk charging cable
is compatible with PD and QC chargers.
Dusk can also be charged with the Dusk Charging Case
(sold separately). The Dusk Charging Case is engineered
to turn off when Dusk is fully charged so Dusk can be left
in the case for extended periods (or indefinitely) without
affecting the battery. For detailed use instructions, read
the Dusk Charging Case manual.
*Warning — Do not attempt to charge Dusk with any
magnetic pogo pin cables or charging cases except for
those made for Dusk by Ampere.
Play/Pause: Single press
Voice Control: 2-second press (to summon
your phone’s default voice assistant)
Answering Calls: Single press

phone microphone and Dusk)

Before using, charge Dusk completely using the included USB-C to pogo-pin charging cable. Dusk
will charge from 0-80% in just 15 min. (or 0-100% in an hour).
The LED will turn red when Dusk is charging and green when charging is complete.
Check battery status in the Ampere app or on your paired Bluetooth devices page.
At 10% battery, Dusk will beep twice and continue to beep twice every 2 minutes (if you are using the
audio functionality). If you would like to continue to be able to adjust the tint level, we recommend
turning off the audio for the remainder of the day.
If you have not used Dusk for 2+ weeks, charge before use.
When Dusk reaches 0% battery, it will revert back to the lightest tint level (38% transmittance).

Be careful when cleaning the lenses. Only clean the lenses with the included lens cloth (or other soft,
clean lens cloths designed for glasses). Be sure to check for any grit or dust that could damage the lens
before rubbing.
Do not use Dusk with any ultrasonic cleaners, even those designed for glasses as they will damage the
lenses. Ampere is not responsible for Dusk that are damaged in this way.
Avoid extremely cold or extremely hot temperatures. If the battery temperature drops below 14°F (-10°C)
or rises above 122°F (50°C), Dusk will stop working.
When not in use, avoid prolonged sun exposure and keep Dusk in either the Dusk soft case or the Dusk
charging case.
Do not submerge Dusk in any liquid. If they do get wet, turn off and allow them to dry naturally in a dark
environment. We recommend wiping down the glasses and giving them time to air-dry before storing or
charging. Do not use an artificial heat source such as a blow dryer.
Charging the glasses while moisture is still present can cause damage.
Do not use Dusk in humid environments like steam rooms, saunas or bathrooms before/after hot showers.
Do not attempt to disassemble, repair or modify Dusk for any reason. Dusk uses a built-in battery. Do not
attempt to replace it.

The tint on Dusk can be set to a level that is darker than traditional sunglasses so make sure you can
see clearly before operating a car, other vehicle or machinery. Dusk glasses set on the darkest tint
are NOT suitable for those activities. Under no circumstance shall we have any liability to you for any
loss or damage of any kind incurred as a result of the misuse of the glasses.
Do not adjust the tint while operating a car, other vehicle or machinery. Only adjust tint levels while
stopped and can do so safely.
Observe all safety warnings and regulations concerning the use of Dusk while driving or operating
machinery.
Consult a physician or the equipment supplier before using Dusk near personal medical equipment.
Do not use Dusk in hospital operating rooms, emergency rooms, intensive care units, etc. to avoid
interfering with medical instruments. Keep Dusk at least 15 cm. away from pacemakers, hearing
aids, cochlear implants, etc.
Listening to loud audio for extended periods can cause damage to your hearing or hearing loss.
Ampere does not recommend using Dusk at high volume for extended periods.
