Sarabec LA240 Room Loop System Instruction Manual

Introduzione

The Sarabec LA240 Room Loop System is designed to enhance the listening experience for hearing aid users by transmitting audio directly to their hearing aids equipped with a "T" or "Loop" program. This system allows users to comfortably listen to TV or other audio equipment without direct connection, providing freedom of movement within the looped area. The LA240 processes audio from various sources and sends it inductively as magnetic sound waves to compatible hearing aids.

Informazioni importanti sulla sicurezza

• NON APRIRE: The LA240 unit contains no user-serviceable parts inside. Opening the casing may result in electric shock or damage to the device and will void the warranty.
• Ensure the power supply used is within the specified range of 12-24 V DC 1.8A.
• Tenere il dispositivo lontano dall'acqua o da umidità eccessiva.
• Avoid placing the unit in direct sunlight or near heat sources to prevent overheating. Ensure adequate ventilation around the device.
• Le dichiarazioni relative agli integratori alimentari non sono state valutate dalla FDA e non intendono diagnosticare, trattare, curare o prevenire alcuna malattia o condizione di salute.

Prodotto finitoview: Rear Panel Connections

The rear panel of the Sarabec LA240 features various input and output connections for integrating the system with your audio sources and the loop cable. Familiarize yourself with these connections before setup.

Image: Rear panel of the Sarabec LA240 Room Loop System. From top to bottom, it shows Microphone inputs (A and B with Priority switch), Analogue RCA inputs (L/R, two sets), Digital inputs (Coaxial and Optical), a headphone output, Loop Amplifier connections (Model No., Serial No.), Loop Cable terminals (0.5-1.5 Ohms), and the DC power input (12-24 V DC 1.8A). A "DO NOT OPEN" warning is also visible.

• Microphone Inputs (A & B): Two 3.5mm jack inputs for connecting external microphones. Input B has a priority switch.
• Analogue Inputs (RCA): Two sets of stereo RCA inputs (Left and Right) for connecting analogue audio sources like TVs, DVD players, or stereos.
• Digital Inputs (Coaxial & Optical): One Coaxial (RCA type) and one Optical (TOSLINK) input for connecting digital audio sources.
• Uscita cuffie: A 3.5mm jack for connecting headphones to monitor the audio.
• Loop Cable Terminals: Screw terminals for connecting the loop cable or loop pad, specified for 0.5-1.5 Ohms impedance.
• Ingresso CC: Power input for the 12-24 V DC 1.8A power adapter.

Istruzioni di installazione

1. Positioning the Loop:

   If using a loop cable, lay the cable around the perimeter of the listening area (e.g., a room or seating area). Ensure the cable is securely fastened and not a tripping hazard. If using a loop pad, place it under a chair or cushion where the user will be listening.

2. Connecting the Loop Cable/Pad:

   Connect the ends of the loop cable or the wires from the loop pad to the "Loop Cable" screw terminals on the rear of the LA240. Ensure a secure connection and proper polarity if indicated.
3. Collegamento di sorgenti audio:

   Choose the appropriate input for your audio source:

   • For TV/Audio Equipment (Analogue): Use RCA cables to connect the audio output of your device to one of the "Analogue" RCA inputs (L/R) on the LA240.
   • For TV/Audio Equipment (Digital): Use either a Coaxial or Optical cable to connect the digital audio output of your device to the corresponding "Digital" input on the LA240.
   • Per i microfoni: Plug a 3.5mm microphone jack into either "Microphone A" or "Microphone B" input.
4. Collegamento dell'alimentazione:

   Connect the provided power adapter to the "DC In" port on the rear panel of the LA240, then plug the adapter into a suitable wall outlet.

Istruzioni per l'uso

1. Accensione:

   Once all connections are made, switch on the LA240 unit. An indicator light (usually on the front panel, though not visible in the provided image) should illuminate.

2. Activate Hearing Aid T-Coil:

   Switch your hearing aid to its "T" or "Loop" program. Consult your hearing aid manual for specific instructions on activating this feature.
3. Adjust Volume and Tone:

   Adjust the volume and tone controls on the LA240 (typically on the front panel, not shown) to a comfortable listening level. These adjustments will only affect the sound transmitted to your hearing aid, not the room's ambient sound.

4. Using Priority Input:

   If you have a microphone connected to "Microphone B" and the priority switch is engaged, audio from this input will override other active inputs. This is useful for ensuring speech is heard clearly over background audio.

Manutenzione

• Pulire l'unità con un panno morbido e asciutto. Non utilizzare detergenti liquidi o spray.
• Assicurarsi che tutti i cavi siano collegati saldamente e non siano danneggiati.
• Conservare l'unità in un luogo fresco e asciutto quando non viene utilizzata per lunghi periodi.

Risoluzione dei problemi

• Nessun suono:
  • Ensure the LA240 is powered on and its indicator light is active.
  • Verify your hearing aid is set to the "T" or "Loop" program.
  • Check all audio input cables are securely connected to both the LA240 and the audio source.
  • Confirm the audio source (TV, stereo) is playing and its volume is adequately set.
  • Ensure the loop cable is correctly connected to the LA240 terminals.
• Suono distorto o poco chiaro:
  • Reduce the volume level on the LA240 or the audio source. Excessive input volume can cause distortion.
  • Check for interference from other electronic devices. Try moving the LA240 or the loop cable away from power cables, fluorescent lights, or large metal objects.
  • Ensure the loop cable impedance is within the specified 0.5-1.5 Ohms range.
• Unit Overheating or Shutting Down:
  • Ensure the LA240 has adequate ventilation. Do not cover the unit or place it in an enclosed space.
  • Verify the power supply is the correct voltage e amperage (12-24 V DC 1.8A). An incorrect power supply can cause issues.
  • Se il problema persiste, interrompi l'utilizzo e contatta l'assistenza clienti.
