For detailed operating instructions refer to section “8 BASIC OPERATION.” POWER SWITCH / VOLUME CONTROL (VOL/PWR) Turns the transceiver on and off as well as adjusts the audio volume. Press and hold this knob for one second to turn the radio on. Clockwise rotation of this knob increases the audio volume level. Press and hold this knob for two seconds to turn the radio off. SQUELCH CONTROL (SQL) Adjusting this control clockwise sets the point at which random noise on the channel does not activate the audio circuits but a received signal will. This point is called the squelch threshold. Further adjustment of the squelch control will degrade reception of wanted transmissions.

Before transmitting, monitor the channel to ensure it is clear. 3 Press the PTT (push-to-talk) switch. The “” indicator in the LCD is displayed. 4. Speak slowly and clearly into the microphone. 5. When the transmission is finished, release the PTT switch. NOTE This is a noise-canceling microphone. The oval slot on the bottom of microphone should be positioned within 1.5 cm from the mouth for optimum performance. 10.3 TRANSMIT TIME - OUT TIMER (TOT) When the PTT switch on the microphone is held down, transmit time is limited to 5 minutes. This limits unintentional transmissions due to a stuck microphone. About 10 seconds before automatic transmitter shutdown, a warning beep will be heard from the speaker(s). The transceiver will automatically go to receive mode, even if the PTT switch is continually held down. Before transmitting again, the PTT switch must first be released and then pressed again. NOTE When a transmission was shut down by the TOT, the GX5000S/GX5500S can not transmit afterwards for 10 seconds. 10.4 SIMPLEX/DUPLEX CHANNEL USE Refer to the VHF MARINE CHANNEL CHART (page 91) for instructions on use of simplex and duplex channels.

To receive a NOAA weather channel, press the [WX] key from any channel. The transceiver will go to the last selected weather channel. 2. Turn the CHANNEL selector knob on the radio or [UP(p)] / [DOWN(q)] keys on the microphone to select a different NOAA weather channel. 3. To exit from the NOAA weather channels, press the [WX] key. The transceiver returns to the channel it was on prior to a weather channel. 10.6.1 NOAA Weather Alert In the event of extreme weather disturbances, such as storms and hurricanes, the NOAA (National Oceanic and Atmospheric Administration) sends a weather alert accompanied by a 1050 Hz tone and subsequent weather report on one of the NOAA weather channels. When the Weather Alert feature is enabled (see section “10.10 WX ALERT”), the transceiver is capable of receiving this alert if the following is performed: 1. Program NOAA weather channels into the transceiver’s memory for scanning. Follow the same procedure as for regular channels under section “9.12 SCANNING.” 2. Press the [SCAN (MEM)] key once to start memory scanning or priority scanning (determined from the “10.7 SCAN TYPE” section, see page 60 for details). 3. The programmed NOAA weather channels will be scanned along with the regular-programmed channels. However, scanning will not stop on a normal weather broadcast unless a NOAA alert is received. 4. When an alert is received on a NOAA weather channel, scanning will stop and the transceiver will emit a loud beep to alert the user of a NOAA broadcast. 5. Press the [WX] key to stop the alert tone and receive the weather report. NOTE If the [WX] key is not pressed the alert tone will be emitted for 5 minutes and then the weather report will be received. NOTE The Weather Alert feature is also engaged while the transceiver is receiving on one of the NOAA weather channels. 10.6.2 NOAA Weather Alert Testing NOAA tests the alert system every Wednesday between 11AM and 1PM.

![FCC ID: K6630283X3S IC ID: 511B-30283X3S GX5000S / GX5500S Operating Manual Channels 68 and 69 are some of the channels available to non-commercial (recreational) boaters. Monitor your desired channel in advance to make sure you will not be interrupting other traffic, and then go back to either channel 16 or 9 for your initial contact. When the hailing channel (16 or 9) is clear, state the name of the other vessel you wish to call and then “this is” followed by the name of your vessel and your Station License (Call Sign). When the other vessel returns your call, immediately request another channel by saying “go to,” the number of the other channel, and “over.” Then switch to the new channel. When the new channel is not busy, call the other vessel. After a transmission, say “over,” and release the microphone’s push-to-talk (PTT) switch. When all communication with the other vessel is completed, end the last transmission by stating your Call Sign and the word “out.” Note that it is not necessary to state your Call Sign with each transmission, only at the beginning and end of the contact. Remember to return to Channel 16 when not using another channel. Some radios automatically monitor Channel 16 even when set to other channels or when scanning. 10.9 MAKING TELEPHONE CALLS To make a radiotelephone call, use a channel designated for this purpose, The fastest way to learn which channels are used for radiotelephone traffic is to ask at a local marina. Channels available for such traffic are designated Public Correspondence channels on the channel charts in this manual. Some examples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87. Call the marine operator and identify yourself by your vessel’s name, The marine operator will then ask you how you will pay for the call (telephone credit card, collect, etc.) and then link your radio transmission to the telephone lines. The marine telephone company managing the VHF channel you are using may charge a link-up fee in addition to the cost of the call. 10.10 OPERATING ON CHANNELS 13 AND 67 Channel 13 is used at docks and bridges and by vessels maneuvering in port. Messages on this channel must concern navigation only, such as meeting and passing in restricted waters. Channel 67 is used for navigational traffic between vessels. By regulation, power is normally limited to 1 Watt on these channels. Your radio is programmed to automatically reduce power to this limit on these channels. However, in certain situations it may be necessary to temporarily use a higher power. See page 20 ([H/L(NAV)] key) for means to temporarily override the low-power limit on these two channels.
