OVERVIEW

Would you like to watch television with crystal-clear sound that won't disturb others in your family? Do you want to avoid hearing damage that could be caused by wearing normal wireless headphones for a long time? SIMOLIO SM-825D Pro wireless TV hearing assistance and protecting headphone is just made for you.
Apply with the latest 2.4GHz Digital Automatic Frequency-Hopping Spread Spectrum (FHSS) technology, it gives you crystal-clear sound with the freedom of a wireless connection - up to 100 feet without obstacles.

• Take the headphone close to the transmitter, then turn on the transmitter and headphone and make sure the green LED indicators are facing towards each other for about 5 seconds.
  
  
  Fig 4-2
  
  Note: If two headphones are used on the same TV, only one transmitter needs to be connected, because one transmitter supports multiple headphones to work simultaneously.

Charge the Headphone

1. Through the USB charging port on the rear of the transmitter base
   You can use the included micro USB charging cable to connect the headphone to the USB charging port on the rear of the transmitter base for charging.(make sure the transmitter base is powered on)
   
   Fig 5-1

   You can charge your headphone by plugging the micro USB power cable into a phone charger (5V/500mA-2A output), PC USB port, TV USB port or any other USB outlet. You don't need to go back to the transmitter base next to the TV to charge. It takes about 3 hours to fully charge the headphones. The LED will turn RED during charging and turn off once charging is completed.
   
   
   Fig 5-2
   
3. Through the battery charging compartment in the base
   A spare battery in the battery charging compartment at the side of the transmitter is always ready.
