The BASICS

Charging Your BE Free6

Although your BE Free6 come with a partially charged battery, it is recommended that you fully charge your BE Free6 and the charging case before first use.

Note: Please remove the film between charging pins and the earbuds in the case before you charge.

1. Place the BE Free6 earbuds into the charging case (1).
   The USB-C charging cable should be connected to the USB-C port on the charging case and to either a PC or a dedicated USB charger.
   When charging, the LED indicator(s) on the earbuds will be in orange. Once charging is complete the LED Indicator on the earbuds’ will turn off.

2. When charging, the LED indicator on charging case (2) will flash white.
   Once charging is complete the charging case LED indicators will be solid white to show how many cycles charge case can fully charge earbuds.

NOTE:
A. It takes up to one and a half hours to fully charge the left/right earbuds and charging case.
B. To maintain the best performance of the battery, we recommend that the battery in both the earbuds and charging case are charged regularly. Do not deplete the battery of the earbuds and charging case before charging.
C. To check the battery level of the charging case:
Open the top cover and check the number of LEDs that are solid white.
If the most left LED indicator is white, the battery can fully charge the earbuds for one cycle.
If the left and middle LED indicators are white, the battery can fully charge the earbuds for two cycles.
If all three LED indicators are white, the battery can fully charge the earbuds for three cycles.

It is strongly recommended that you charge the charging case immediately when the most left LED indicator turns orange.

Please note, low battery of the charging case might cause abnormal functionality such as auto on and auto off.

MISCELLANEOUS

Water Resistant

NuForce headsets with the IPX5 water ingress rating are splash-resistant and water-resistant, preventing malfunctions due to moisture entering the body of the headset. However, the splash-resistant and water-resistant qualities are non-permanent and may degrade with wear and tear from daily use. Liquid damage is not covered by the warranty.

• To prevent liquid damage, please avoid the following situations:
  • Wearing the headset while swimming or showering
  • Exposing the headset to pressurized or high-speed water, such as showering, water skiing, wakeboarding, surfing or riding a water scooter, etc.
  • Using the headset in a sauna or steam room
  • Immersing the headset in water
  • Operating the headset outside the recommended temperature range, or in extremely humid conditions
  • Dropping the headset or any other actions that cause the headset to take impact
  • Disassembling the headset, including the disassembling of screws

• Types of liquids covered by the water resistance rating: The water resistance rating only applies to fresh water and tap water. Other liquids such as the following are not within the scope of the water resistance rating: soap water, solutions mixed with detergents, solutions mixed with bath products, shampoos, hot spring water, swimming pool water, seawater, soap water, detergents, salt water, perfumes, insect repellents, lotions, sunscreens, oils, gel removers, hair dyes, and solvents.

• If the headset has already come into contact with liquids, do not charge the headset until it is fully dry. Using or charging the headset or accessories while they are wet may damage your headset.

• The charging box (if any) containing the genuine wireless Bluetooth headset does not have a waterproof design. Any water-resistant qualities described in the product specifications are limited to the body of the headset.

14

If the headset is not wiped after being worn during a workout, the salt from the sweat may negatively impact the lifespan of the headset. Therefore, we recommend that you use a clean cotton cloth to wipe the headset after your workout, in order to keep the headset clean.

Bluetooth Connectivity

Bluetooth is a short-range wireless technology. Its connection quality may be interfered with metals, walls, and devices including but not limited to microwave ovens. At the same time, Bluetooth’s 2.4 GHz frequency is also shared by some Wi-Fi connections, which may result in a slower connection. This technical problem cannot be completely eliminated despite Bluetooth’s status as an international standard.

A Bluetooth headset’s wireless transmission is not limited to the connection between the headset and the signal transmission device, but also between the main and auxiliary earbud. Therefore, when using a genuine wireless Bluetooth headset, we advise placing the signal transmitting device (such as your cellphone) on the same side as the main earbud in order to reduce the potential technical limitations of Bluetooth signal shielding to some extent.

The connection quality of the Bluetooth headset is influenced by factors such as the Bluetooth device connected to the headset, the communication environment, or the environment in which it is used. If the headset audio is intermittent, please run through the following scenarios to identify and avoid the following caused by environmental interference:

• There are obstacles such as people, metal objects, or walls between the headset and the Bluetooth device.
• There is a Wi-Fi device in use near the headset.
• There is a microwave oven in use near the headset.
• There is an electromagnetic radiation generating device in use near the headset.
• The distance between the headset and Bluetooth device exceeds 10 meters.
