  3. Inspect the device for damage to optical surfaces, body, eyecups, operation buttons, etc.
  4. Ensure that all optical surfaces are clean and ready for use.

If any accessories are missing or broken contact ATN’s Customer Service at 1.800.910.2862.

Charging the device

The device is equipped with a USB (type C) port. You will find it under the rubber cap on the right side of the device (caps are marked with appropriate icon).
Use the included USB (type C) charging cable with your binocular. Plug the cable into a USB wall charger that has an output of 2 amps (Wall Charger not included).

Using a wall charger with lower amperage will increase charge time on your binocular.

  1. Recommended charger is 2A USB charger.
  2. Battery charging time (from 0 to 100%) is 6 hours with 2 A USB charger.
  3. Battery run time is 15 hours on a single charge.
Micro SD and USB C Ports

The device is equipped with a microSD Card port and USB (type C) port. You can find them under the rubber cap on the right side of the device (we marked the cap with appropriate icons).

Make sure that the device is turned off before inserting the formatted microSD Card into its assigned port.

  1. Always format a new microSD card before using.
  2. Insert microSD card as shown.
  3. Use a thin object (small coin, paper clip) to lock the microSD card in place after inserting it into the slot.
  4. Return the cover to its original position.


There is only one correct direction to insert the microSD Card.
Do not force the microSD Card into the port doing so may cause damage to both the binocular and the card itself.

To remove the microSD Card from the port, push the card slightly in using the same thin object you did before. When the card pops up a few millimeters, pull the card out with your fingers or tweezers.
