Quick Start Guide
Charge
Before using, charge Dusk using the included USB-C to pogo-pin charging cable. A full charge will take about one hour. The LED indicator will turn red when Dusk is charging and green when charging is complete.
Power On
Hold the “Right Arm Button” for 3 seconds to turn on Bluetooth and audio functionality. When Bluetooth and audio are turned on, Dusk will automatically go into Bluetooth pairing mode and the LED will blink red and green. Hold the “Left Arm Button” for 3 seconds to activate the tint adjusting functionality.
Connect
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!
Fit
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.
Warnings
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.
Right Arm Button
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 will play.
Power Off: Hold for 3 seconds. A red LED will illuminate for 3 seconds and the “power off” sound will play.
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.
Play/Pause: Single press Voice Control: 2-second press (to summon your phone’s default voice assistant)
Answering Calls: Single press
Hang up: Single press
Reject call: Double press
Toggle Audio: Double press (between phone microphone and Dusk)
Next Song: Double press

Left Arm Button
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.
Deactivate Tint Level Adjustment: Hold for 3 seconds.
Adjust Tint Level: Single Press
Level 1 (Default): 38%
Level 2: 30%
Level 3: 14%
Level 4: 8%

Tip — If you find that that the tint level is not adjusting, try resetting by holding the left arm button for 3 seconds.
charging
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.
battery
- 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).
Notes On Cleaning & Care
- 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.
Warnings
- 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.
