2.5.6 Auxiliary Input
Your RAY 430 has been designed to allow you to amplify the audio from your VHF
radiotelephone or any other external audio output (i.e. AM/FM radio, CD player)
through your intercom or deck speaker stations. This external audio input can be
connected at the auxiliary input terminals 1 and 2.
2.5.7 Connection of an External Speaker
In situations where the main unit is distant from the operator and the noise level is very
high, it may be difficult to hear your RAY 430 clearly. By connecting an external (8
ohms, 5 watts or more) speaker, the sound level can be increased for improved listening
capability. When an external speaker is connected at the external speaker jack, the
internal speaker is automatically disconnected. The connector, a mini phone plug, for
the external speaker is supplied with your RAY 430 for your convenience.
