Operating Advice: Use of Internal Microphone
Your
FTA-450L
is sealed against water ingress, which includes waterproof seals around
the microphone and speaker enclosure. This requires that you focus your speech in the
direction of the microphone’s location, so as to ensure sufcient voice input to the radio.
Refer to the illustration and observe the location of the internal microphone.
If you nd it difcult to utilize the
FTA-450L
conveniently and safely while speaking
directly into the microphone, we recommend the use of the
SSM-10A
Speaker/Micro-
phone (option), or an aftermarket aviation headset with boom microphone.
