Note: Key press beep volume is also controlled by the VOL level. 30 Ray101 Handheld VHF Radio 4. 3 Setting the Squelch The Squelch circuit sets the threshold for cutting off the receiver when the signal is too weak for reception of anything but noise. To properly set the squelch, rotate the SQ knob counterclockwise until noise is heard. Then rotate clockwise until background noise disappears. D6705-1 4. 4 Setting the Power Output Press and release the HI/LO / USER key to toggle the TX power from LOW (1 watt) to HIGH (5 watts). You should switch to high power only when contact can not be made on low power in emergency situations. This procedure is specified by the FCC but is also part of marine communications courtesy and will save on battery life. Note: Some channels are limited by regulation to be low power only. If the HI/LO operation request is denied, an error tone beeps. Chapter 4: Operating the Radio 31 Overriding the Low Output Power Restriction (US only) The low power requirement on channels 13 and 67 in US mode can be temporarily overridden in cases where 1W is not sufficient. To override the LO power restriction on channels 13 or 67 and transmit at high power: Press and hold the PTT key. Output is set to HI power for as long as you hold down the HI/LO / USER key. D6698-1 Note: Channels 13 and 67 are for bridge to bridge operations only. See Appendix B:Channel List for approved usage. 4. 5 Setting the Channel Press and release the UP arrow to increment the channel number. Press and hold either key for rapid channel scrolling. 4. 6 Selecting a Weather Channel The US National Oceanic and Atmospheric Administration (NOAA) broadcasts continuous weather reports and severe weather alerts, as needed. The Ray101 is programmed to receive10 NOAA weather channels and sound an alarm if a weather alert is received. Press Channel UP/DOWN to change the WX channel 1 through channel 10. 32 Ray101 Handheld VHF Radio Press and release the WX/BAND key again to return to normal operation. During Weather mode, the PTT, SCAN/SAVE and HI/LO / USER keys are disabled and an error beep sounds if pressed. Weather Alert Operation Weather Alert is toggled ON and OFF by pressing and holding WX/BAND key in the weather mode. The ALERT icon illuminates. When Weather Alert function is enabled and the radio is tuned to the normal working channel, the last-used weather channel is checked every 30 seconds for weather alert tone. If the alert tone is detected, the WX and ALERT indicators flash and a short alarm tone sounds. The radio automatically turns to the currently-monitored WX channel where the weather alert has been detected. The alert is detected in all modes of operation (Standby, Dual and Tri Watch, Scan, etc. ) Chapter 4: Operating the Radio 33 4. 7 Setting the Frequency Band The Ray101 can transmit and receive on all available US, Canadian and International marine VHF radiotelephone channels. Press and hold the WX/BAND key for greater than 3 seconds while in normal operation mode to alternate between the International, US and Canadian channel sets. The appropriate indicator is illuminated in the LCD: U for US, I for International, or C for Canadian channel sets. Note: Pressing and holding the WX/BAND key for greater than 3 seconds while in Weather mode toggles the Weather Alert mode. 4. 8 Selecting Priority Mode The Ray101 provides you with a dedicated key for selecting Priority Mode, which instantly switches the radio to Priority Channel 16 at high power. If not already tuned to the Priority Channel 16, press and release the 16/9 key to place the radio into Priority Mode. Note: When you press the 16/9 key, the radio always switches to HIGH power. The following describes the results of pressing the various keys during Priority Mode: · 16/9 Press and release to return to the last-used working channel. [. . . ] Channel 16 is used for calling other stations or for distress alerting. The letter "B" following a channel number indicates simplex use of the coast station transmit side of an international duplex channel. Channel 70 is used exclusively for Digital Selective Calling (DSC) and is not available for regular voice communications. Channels 75 and 76 are reserved as guard bands for Channel 16 and are not available for regular voice communications.
