Special Tips

1. Radiofrequency Exposure

The Hs910 is an audio transmitter and receiver that communicates with Bluetooth enabled mobile devices by

receiving and transmitting radio frequency (RF) electromagnetic fields (microwaves) in the 2.4-2.48 GHz

frequency range. This product is designed to operate in accordance with guidelines and limits for radio frequency

exposure established by national authorities and international health agencies when using compatible mobile

phones.

2. Battery Information

Proper use of rechargeable batteries can prolong their service life.

New batteries or batteries that have not been used for a long time will have less power at the first few times of use.

Do not expose the battery to extreme temperatures, not exceeding 50 degrees or less than -10 degrees.

For maximum battery capacity, use the battery at room temperature.

Using the battery at low temperatures reduces the amount of power. Charge the battery only in the following

temperature range of 10-45 degrees.

There is a risk of explosion if the battery type is not replaced properly. Follow the instructions to dispose of the

used battery.

3. Removing Used Batteries and Accumulators

(This product uses embedded batteries only)

As end users cannot easily dismantle the built-in batteries of this product, we recommend that only qualified

professionals dismantle the batteries, whether by replacing them or recycling them at the end of the product's

useful life. To prevent damage to this product and to protect the safety of the user, the user shall not attempt to

Warning:

If there is a risk of explosion if the battery is not replaced properly, the end user must not replace the lithium

battery in the device without authorization, but must use the appropriate type of battery by an authorized service

Avoid hearing loss

The headphones are too loud and can cause permanent hearing loss. Set the volume to a safe level. If you are

accustomed to listening to the sky volume, the sound may sound normal, but it will damage your ears. If you have

an echo in your ear or can't hear clearly, stop using headphones and have your ears examined by a specialist. The

louder the volume, the easier it is to lose your hearing.

Hearing protection suggestions of experts

Reduce the amount of time you spend using headphones at high volume.

Avoid the habit of turning up the volume to mask ambient noise.

If you can't hear people around you, turn down the volume.
