SECTION 3 OPERATIONS

3.1 INTRODUCTION

Your RAY210 has the capability to transmit on 51 and receive on 93 Marine VHF radiotelephone channels. There are channels that are FCC approved but may only be used by authorized stations for specific purposes, depending on the type of vessel (commercial or non-commercial). Take a look at Table 3-1 and 2 on page 22-24 which lists all of the marine VHF channels available in your RAY210 for International and U.S. radiotelephone use. Full familiarization with this table is essential when selecting your channels. The international frequencies were agreed upon by the attending countries at the 1968 International Telecommunication Union Meeting in Geneva and are in active use around the world. The U.S. channels are those channels authorized for use in the U.S.A. by the FCC.

3.2 CONTROLS AND LCD DISPLAY

Refer to Figure 3-1 for familiarization with the controls and mode display.

3.2.1Controls

1)On / Off and Volume Control:

This control switches the RAY210 on and off and controls the volume level of the internal speaker. Turning the radio On will apply power to the radio circuitry. When the radio is on, rotating this control clockwise will increase volume to the internal speaker and rotating this control counterclockwise will decrease volume.

2) CHANNEL Selector Control

This control selects the desired operating channel. When the control is turned in a clockwise direction, the channel number increases. When the control is turned in a counterclockwise direction the channel number decreases.

3) SQUELCH Control

Provides an adjustable input signal threshold to eliminate random RF background noise during “no signal” conditions. This control sets the signal-to- noise ratio at which a signal will become audible.

4) [16/9] Key

Used to select channel 16 or 9 immediately. This Key enables the following operating mode;
