Guia de configuració
Follow these steps to connect your SIMOLIO Wireless Portable TV Speaker to your television or audio source.
1. Carregant l’altaveu
Before first use, fully charge the speaker. Place the speaker onto the charging base, ensuring the charging contacts align. Alternatively, you can connect one of the provided AC adapters directly to the speaker's charging port for continuous use. A full charge typically takes 3 hours and provides up to 6 hours of continuous operation.

2. Connecting the Transmitter to Your TV
The transmitter (charging base) connects to your TV's audio output. Choose one of the following connection methods:
Optical Audio Connection (Recommended for Digital Audio)
- Connect one end of the Digital Optical Cable to the "Optical Out" port on your TV.
- Connect the other end to the "Optical In" port on the SIMOLIO transmitter.
- Ensure your TV's audio output settings are configured to "PCM" or "Stereo" for the optical output. Some TVs (e.g., Vizio) may require audio settings to be set to "Fixed".
- If your TV's optical port is already in use by a soundbar, an optical splitter (sold separately) will be required.
RCA Audio Connection (Analog Audio)
- Connect the RCA Audio Cable (red and white plugs) to the "Audio Out" (L/R) ports on your TV.
- Connect the other end of the RCA cable to the corresponding RCA input ports on the SIMOLIO transmitter.
3.5mm AUX Audio Connection (Headphone Jack)
- Connect the 3.5mm AUX Audio Cable to the headphone jack or "Audio Out" port on your TV.
- Connect the other end to the 3.5mm AUX input port on the SIMOLIO transmitter.
- Note: Plugging into the TV's headphone jack may silence the TV's internal speakers. Consult your TV manufacturer for details.

Private Listening with Headset
For private listening, connect the included stethoscope headset to the speaker's headphone jack. This allows you to listen to TV audio without disturbing others, even if the TV's main volume is muted.

Multiple Speakers (Optional)
This system supports connecting multiple SIMOLIO speakers to a single transmitter, allowing you to share the TV audio experience in different rooms. If using two sets of speakers on two different TVs in the same household, ensure a distance of at least 10 meters between them to avoid interference.

Manteniment
- Cura de la bateria: When the speaker is powered directly by an AC adapter for extended periods, it is recommended to remove the battery to prevent potential swelling or damage.
- Headset Ear Tips: The stethoscope-style headset comes with memory foam ear tips. It is suggested to replace these every 30 to 60 days for optimal hygiene and performance. Replacement ear tips are sold separately.
- Neteja: Wipe the speaker and transmitter with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
