2.5.6 Auxiliary Input
Your RAY430 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 RAY430 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 RAY430 for your
convenience.
