Operating Advice: Use of Internal Microphone
Your
FTA-750/FTA-550
are extensively sealed against water ingress, so as to ensure
reliable operation even if it has become submerged. This unique construction includes
waterproofing seals around the microphone and speaker enclosure, requiring that care be
exercised when speaking into the internal microphone.
Please refer to the illustration, and observe the location of the internal microphone. It is
important that you focus your speech in the direction of the microphone’s location, so as
to ensure sufficient voice input to the radio.
If you find it difficult to utilize the
FTA-750/FTA-550
conveniently and safe while
speaking directly into the microphone, we recommend the use of the
SSM-10
A
Speaker/
Microphone (option), or an after-market aviation headset/boom microphone.
