1. OPERATION
1.1INTRODUCTION
Your RAY53 has the capability to transmit and receive on all available US,International and Canada 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 noncommercial.) Refer to Table 1-1 . These table list all of the marine VHF channels available in your RAY53 for Canada,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 US channels are those channels authorized for use in the U.S.A. by the FCC.

1.3 OPERATING PROCEDURES
1.3.1Turning the Power On
1) Rotate the VOLUME knob clockwise to turn the radio on.
1.3.2Setting the Volume
1)Rotate the VOLUME knob for the disired volume level.
1.3.3. Setting the Power Output
1) Simply press the “MON 1/25” key for two seconds to toggle between 1 Watt output and 25 Watt output. When “1 WATT” is displayed,the output power is 1 Watt.
If “1 WATT” is extinguished, 25watts is being output. The choice of power output is dependent upon the distance of transmission and transmitting conditions. In certain US harbors and on certain channels, the FCC requires the power to be limited to
1 Watt. On these “required “ channels,the radio automatically selects 1 Watt power output when the channel is selected.
1.3.4Selecting the Channel
1)To select the appropriate channel, rotate CHANNEL SELECTION Knob clockwise / counterclockwise or also press UP/DOWN key of the microphone.
2)The channels which are not set on the frequency mode are skipped .
3)When UP/DOWN key is continuously pressed for over 0.5 seconds,the channel is continuously changed(+1 or – 1) every 100msec during pressing UP/DOWN key.
1.3.5To select the frequency mode
1) The frequency mode(group) can be selected from US mode, International mode and Canadian Mode.
The frequency mode can be shown on the LCD as follows.
USA frequency mode---------------------------- |
Æ “INT” and “CAN” are eliminated |
CANADIAN frequency mode------------------ |
Æ “CAN” is displayed and “INT” is |
eliminated. |
|
INTERNATIONAL frequency mode---------- |
Æ “INT” is displayed and “CAN” is |
eliminated. |
|
When WX/INT key is pressed and held for over 2 seconds, one frequency mode can be changed to the other frequency mode and Alerm 1 is heard.:
For example:
When USA mode is in use,it can be changed to CANADIAN mode by doing above operation.
When Canadian mode, it can bew changed to International mode. When International mode,it can be changed to USA mode. The last changed frequency mode can be memorized.
When the power is turned on,the last memorized frequency mode can be used.(Channel number is16CH at that time.)
1.3.6To Transmit
1)Press the Push-To-Talk switch(PTT switch) and speak into the microphone using a clear normal voice.
2)If the current channel is Weather CH or the Tx prohibited channel, PTT switch cannot be used and Audible beep sound 2 is heard.
3)RAY53 is designed to meet the new FCC Rules Part 80.203, which states,if the PTT switch is pressed continuously for over five minutes,transmission is forcibly inhibited. If this occurs,audible beep sound 2 will be heard until the PTT switch is released.
1.3.7To select a Weather Channel
1)Simply press the WX/INT,then use Channel Selection Knob or UP/DOWN key to
select the desired Weather Channel from 0 to 9. When this mode is selected,the transmitter is always inhibited.
2)When the Weather CH is finished by pressing WX/INT key,the last used Weather CH number is memorized
3)When the power is re-turned on,the memorized Weather CH number can be activate on the Weather CH mode.
1.3.8Priority Channel
1)When 16/9 is pressed and released, Alarm 1 is heard and Priority Channel is in use then Channel Display(Small) shows “P” on the LCD.(“P” display means “Priority CH”.)
2)When 16/9 key is pressed and released again during “P” is diplayed, Alerm 1 is heard and the channel will be returned to the privious Working CH. When the channel is changed by UP/DOWN key during Priority CH is displayed, “P” display will be eliminated and Workimg CH will be in use.
3)When 16/9 is continueously pressed for over 2 seconds, Alerm 1 is heard and Priority channel can be changed either 16CH or 9CH.(When Priority CH is 16CH, it can be changed to 9CH and when Priority CH is 9CH,it can be changed to 16CH.)
1.3.8Channel Memory
1)The RAY53 has the capability of memorizing all US,International and Canadian Channels. The channels memorized will be scanned in the Memory Scan mode.
2)Channel Memory: When SCAN/MEM key is pressed and held for over 3 seconds,the
audible beep sound 1 is heard and the selected current channel can be put into memory.
When the displayed channel on the LCD is memorized, “MEM” is displayed on the LCD.
Memory Clear : To press and hold for 3 seconds when the memory channel is stored, the audible beep sound 1 is heard and the channel can be cleared
When the displayed channel is not memorized,”MEM” is not displayed on the LCD.
1.3.9Scan Modes
The RAY53 is equipped with two types of scan options, All-scan and Memory Scan. How these options are accessed is dependent upon whether there are any channels stored in memory.
1)All-Scan mode
If no channels are stored in memory,when the SCAN/MEM key is pressed and
released, the audible beep sound 1 is heard and ”SCAN” will begin to flash on the LCD for three seconds. If no other keys are pressed in these three seconds,the radio will begin scanning all channels(except weather channels) as long as no signal is received. If a signal is received,the scan will stop on the receiving channel. If the signal is lost for five seconds, the
radio will resume scanning. While the radio is scanning ALL-Scan,”SCAN” is displayed on the LCD.
To cancel the scan mode,press the SCAN/MEM key while the radio is scanning.
2)Memory Scan mode
If one or more channels are stored in memory,when the SCAN/MEM key is pressed and released, the audible beep sound 1 is heard and “SCAN” and “MEM” will begin to flash simultaneously on the LCD for 3 seconds. If no other key is pressed in these three seconds, the radio will begin scanning all channels currently in memory.(Begin Memory scanning) As with All-Scan, If a signal is received,the scan will stop on the receiving channel until the signal is lost for five seconds, the radio will resume scanning.
While the radio is scanning Memory Scan, “SCAN” and “MEM” are displayed on the LCD. To cancel memory scan,press the SCAN/MEM key while the radio is scanning.
When SCAN/MEM key is pressed again during “MEM” flashing within these three seconds, the audible beep sound 1 is heard and “SCAN” will flash on the LCD and the radio will begin ALL Scan mode. “MEM” will disaprear from the LCD leaving only “SCAN” flashing.
1.3.10 Monitor operations
1) The RAY53 is equiped with 2 types of monitor operations, Dual Watch opeartion and Tri Watch operation.
Working CH and Priority CH can be monitored alternately in Dual Watch operation. Working CH, Priority CH and Weather CH can be monitored by turns in Tri Watch operation.
2)Dual Watch and Tri Watch can be changed each other by using WX/INT key. When WX/INT key is pressed and released in the monitor mode, Alerm 1 is heard and Dual Watch and Tri Watch can be changed each other alternately.
