Solaris Flex with Med-El Opus 2 What you need: • MicroLink MLxS receiver • OPUS 2 FM battery cover (This is slightly longer than the standard battery pack cover). • FM adaptor cable
What to do: 1. Turn off the speech processor, FM receiver and transmitter. 2. Open the battery pack lock:
3. Slide off the battery pack cover. 4. Slide on the FM Battery Pack Cover which is slightly longer than the standard battery pack. 5. Close the battery pack lock. 6. Plug the grey end of the adaptor cable into the base of the FM battery cover. The yellow plug should then be plugged into headphone socket on the Solaris Flex.The device will detect the receiver automatically. There is no need to select a particular program. 7. In this order: - turn on the FM transmitter - turn on the FM receiver -turn on the OPUS 2 by closing the battery latch.
8. Gradually increase the volume on the FM receiver to a comfortable listening level. 9. Complete a subjective listening check. 10. It is advised to leave the transmitter on during the lesson. The teacher should simply use the microphone mute facility (star button) on the transmitter if the child does not need to listen to the input for a time. When the teacher wants to speak to the child again, they simply press the star button again. 11. Turn the receiver off before turning the transmitter off. When the system is not in use it should be turned off.
Troubleshooting the FM system 1. Check the function of the FM system in isolation: You can use the accessories tester from Connevans (part number FMG750) to check the microphone with its lead. Gently wiggle or bend the leads. Intermittent connections will cause bad crackling and or interruption of sound. To check the FM system you could use the Headset Checker (Phonak part number 052-3126). Remove the receiver from the processor and plug into the headphones. Switch on the receiver and the transmitter. Listen for a clear signal. Or check the FM using a working hearing aid and audio shoe. Plug the receiver into the audio shoe, switch on the hearing aid and then the transmitter and listen to the signal through a stetoclip. 2. Check the function of the processor in isolation: Check the batteries and power of the processor 3. Check the function of the processor using the Sound Processor Test Device. The LED light on the SPTD should flicker with voice pattern.
4. Replace the standard battery sleeve with the FM one and check the function of the FM battery sleeve. Use an additional direct input device such as an iPod to verify that the battery sleeve is working / that the child reports hearing the output from the iPod. 5. Assess the function of the FM system and processor working together using the Sound Processor Test Device. a. Assess the function of the processor with the FM sleeve on (The LED light flickers to voice. b. Connect the FM system. Move far enough away so that sound from your voice no longer activates the SPTD. c. Switch on FM and speak into the FM microphone (LED should flicker to voice coming in via the FM). Brightness and fluctuation should be similar to how it was in (a) above. If there is no flicker, consider an FM fault, not i) transmission. ii) If there is a constant light then the FM gain may be too high and there is too much noise iii) If the light is very bright, the gain may be too high.
Things to check: • Are the FM transmitter and receiver on the same channel? • Are the cables on the FM transmitter or receiver frayed or kinked? • Has the transmitting distance been exceeded? • Do the batteries for the FM transmitter and or the receiver need replacing? • Is the microphone on the transmitter working?
• Are the FM settings set appropriately? • Has the processor program been audio mixing enabled? • Have you observed areas in the classroom that can cause dead spots in the transmission by checking with the FM system yourself? • Have you tried reducing the volume or gain on the FM receiver? • Have you tried a different FM channel? • Have you replaced the FM adaptor cable to check if it is working? • Have you replaced the direct connect cable? • Have you definitely turned on the microphone? Particular care is needed with the Campus transmitter where there is a switch on the microphone itself.
