Yes. It is important that you notify OSHKI that you intend to participate from a Contact North Access Centre. OSHKI will then book your seating arrangements with Contact North to ensure that you have a workstation available for your use at the designated date(s) and time(s).
You are responsible for replacing a lost, damaged, or stolen headset at your own expense. An inexpensive headset can be purchased at most retail stores for about $20. If you cannot purchase a headset in your home community OSHKI will charge you for a new unit. If you suspect your headset is faulty due to workmanship please return it to OSHKI for repair or a replacement unit.
If you can't hear your instructor:
- Check that the volume control knob located on your headset's cable length is turned on all the way to the left (max volume).
- Test your headphones by plugging the headphone plug into an MP3 player or similar audio device:
- cell phone or PDA
- iPod player
- gaming console
- stereo/radio receiver
- If you cannot hear any audio then most likely the headphones are at fault.
- Check that the Windows volume control is turned on. On your computer click the speaker icon located on your Windows taskbar (bottom right-hand corner) to ensure that it is not muted or turned on low.
- Check that the Windows sound management software is correctly configured. Some computers monitor the headphone and microphone jacks - when you plug-in a headphone or microphone device into your computer the computer will detect it and will ask you to confirm the correct hardware being used.
If the audio breaks up or buzzes:
- Check that your microphone is working correctly. Test it (record yourself) using an MP3 player or similar device:
- stereo receiver
- karaoke machine
- home theatre
- You might need a 3.5 mm female to 1/4" male headphone adapter to test your headset's microphone on audio equipment:
- Some laptops operating on battery power will cause interference on the microphone line resulting in a buzzing sound when trying to speak into the microphone (the listeners will hear it). Try switching to the laptop's power adapter. If still unsuccessful, you should try using a desktop computer instead.
- Highly magnetic devices such as speakers will cause noise/echo on the microphone line (the microphone cable acts as an antenna). Try moving away from such devices.
- Check your network status indicator located at the bottom right-hand corner of the Centra interface. A low indicator will indicate a poor/slow Internet connection resulting in audio breakup.
- Switch to text chat if you cannot resolve the issue.
