[. . . ] Ray101 Handheld VHF Marine Radio Owner's Handbook Document number: 81229-2 Date: February 2004 iii About this Handbook Introduction This handbook describes the Ray101 portable VHF marine radio. The Ray101 provides communications on all US, Canadian and International marine channels and receives ten weather channels. Conventions Used Throughout this handbook, the dedicated (labelled) keys are shown in bold capitals (for example: SCAN/SAVE). The LCD indicators and functions are shown in normal capitals (for example: TX). Operating procedures, which may consist of a single key-press or a sequence of numbered steps, are indicated by an arrow icon shown in the margin. Technical Accuracy To the best of our knowledge, the information in this handbook was correct as it went to press. However, our policy of continuous product improvement and updating may change specifications without prior notice. [. . . ] Turn clockwise to increase the volume; counterclockwise to decrease the volume. Note: Key press beep volume is also controlled by the VOL level. 16 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). The corresponding LO or HI indicator appears on the LCD. Initial contact should always be attempted using low power. 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 17 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. Press and hold the HI/LO / USER key while continuing to hold PTT. 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: for approved usage. 4. 5 Setting the Channel Press and release the UP arrow to increment the channel number. Press and release the DOWN arrow to decrement the channel. 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 and release the WX/BAND key to enter Weather mode. Press Channel UP/DOWN to change the WX channel 1 through Channel 10. 18 Ray101 Handheld VHF Radio Press and release the WX/BAND key again to return to normal operation. Weather broadcasts can only be heard in the North America. 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. [. . . ] 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.
