Use Two Sets of SIMOLIO 2.4GHz Wireless TV Headphones Simultaneously in the Same House
- The two sets of SIMOLIO 2.4GHz units should be put at least 10 meters away from each other when using them simultaneously.
- 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.
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
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)
Through the universal USB charger/outlet
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.
Notes: The charging time is approx. 3 hours. Before using the spare rechargeable battery for the first time, charge it for at least 3 hours. The headphone battery will last around 10 hours on a full charge, but will last a lesser or greater amount of time depending on the average volume level of the headphone.
Customizing your SM-826D
Please make sure the headphones are being worn properly. Each side of the headphone has a letter to guide the wearer: “L” for left and “R” for right. You can adjust the retractable headband to fit you better.
Tone Control: Select the TONE (TREBLE/NORMAL/BASS) at the rear of transmitter to find the best feature, make sure you can hear the TV voice clearly.
Mono/Stereo option: You can switch to STEREO for enjoying Hi-Fi sound quality music or select MONO for enjoying more clear TV dialogues. If, despite a correct balance adjustment, you can hear the sound only with one ear: Set the STEREO/MONO switch on the transmitter to MONO. (Ref. Fig 6-3)
