Sarabec LA240 Room Loop System Instruction Manual

Zavedení

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.

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.
• Sluchátkový výstup: 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.
• DC vstup: Power input for the 12-24 V DC 1.8A power adapter.

Pokyny pro nastavení

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. Připojení zdrojů zvuku:

   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.
   • Pro mikrofony: Plug a 3.5mm microphone jack into either "Microphone A" or "Microphone B" input.
4. Připojení napájení:

   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.

Návod k obsluze

1. Zapnutí:

   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.

Údržba

• Čistěte přístroj měkkým, suchým hadříkem. Nepoužívejte tekuté čisticí prostředky ani aerosoly.
• Ujistěte se, že všechny kabely jsou bezpečně připojeny a nejsou poškozené.
• Pokud přístroj delší dobu nepoužíváte, skladujte jej na chladném a suchém místě.

Odstraňování problémů

• Žádný zvuk:
  • 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.
• Zkreslený nebo nejasný zvuk:
  • 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 a amperage (12-24 V DC 1.8A). An incorrect power supply can cause issues.
  • Pokud problém přetrvává, přestaňte jej používat a kontaktujte zákaznickou podporu.
