BASICS

Power On/Off

1. Press and hold to turn the radio ON. A channel number and  battery level should appear on the display.
2. Press and hold to turn the radio OFF.

Volume

The volume level can be adjusted from 0 (no volume) to 15 (maximum volume).

Press

or to increase or decrease the volume level. The current volume level flashes.

Select a Channel

Press

or to scroll though the channels individually.

Press and hold

or to scroll rapidly through the channel numbers. 

Set Squelch

Use squelch to eliminate any annoying background noise when there are no signals present.

NOTE: Make sure to first select a channel not in use before setting the squelch.

Think of the squelch control as a gate. If you increase the squelch level to maximum, it raises the “Squelch Gate” so only the strongest signals get through.

 

If you decrease the squelch level to minimum, it lowers the “Squelch Gate”’ to the extent that weak signals can get through.

 

 

If unwanted weak and noisy signals are getting through, increase the squelch level (raise the “Squelch Gate”) to a medium level. Now only medium and strong signals get through.

 

S1 – minimum squelch
S2 – medium squelch
S3 – maximum/tight squelch

1. Press SQL UIC. SQL displays and the current squelch level flashes.
2. Press SQL UIC while the squelch level displays to change the squelch level to the next step (0 – 3, then repeating again from 0).
3. After 2 seconds the unit exits the squelch setting.

TRANSMITTING AND RECEIVING

Selecting Channel Modes

The radio uses U.S., Canadian, and International Marine channels (modes). Press and hold SQL UIC to change modes. Each time you press and hold SQL UIC, the mode indicator changes (US – United States; CAN – Canada; INT – International). Refer to page 28 for a list of the available channels and corresponding frequencies.

Transmitting

The radio can transmit for up to 3 minutes. TX displays when transmitting. After 3 minutes of continuous transmission, transmission is canceled and an error tone sounds.
The radio transmits at 1W; press BOOST to transmit at 3W.

Boosting Transmission Power

1. Hold the radio approximately 2 inches in front of your mouth with the antenna at approximately 45º angle away from your head.
2. Press BOOST on the side of the radio to change the transmit power from Low (1W) to High (3W). Speak in a clear, normal, conversational voice.
3. When you have finished speaking, release PTT or BOOST to listen for a response. TX then disappears.
4. When the channel is clear, press and hold PTT or BOOST to transmit. TX displays again.

Receiving

Release PTT or BOOST to receive another party’s transmissions to you.

HOW IT WORKS

Your radio has three main operation modes: normal, scan, and weather.

In addition to the three operation modes, your radio provides two different watch modes which you can activate during any operation mode. In the watch modes, the radio briefly checks for activity on a specific channel, then returns to its previous operation.

NORMAL MODE OPERATION

• To transmit, remove the radio from the charger, then press and hold the PTT key. Release the key when you are finished talking. x For the best sound quality, hold the microphone about two inches from your mouth while you’re talking.
• Press thekey to move up one channel at a time. Press and hold the key to scroll quickly up the channels.
• Press the key to move down one channel at a time.
  Press and hold the key to scroll quickly down the channels.
• To change the transmit power, press the H/L LOCK key. The transmit power switches to the next transmit power each time you press this key.

Normal mode with Weather Alert Watch

If you activate Weather Alert Watch while operating in normal mode, the radio checks Monitoring Channel 25 the most recently used weather channel every seven seconds. If it detects a weather or other hazard alert, it will switch to that weather channel. (If you are transmitting or receiving an active transmission, the radio waits until the channel is clear or you finish your transmission before checking the weather channel.)

Normal mode with Triple Watch

If you activate Triple Watch while operating in normal mode, the radio checks channels 9 and 16 every two seconds. The radio will not check channels 9 or 16 while you are actively transmitting; it waits until your transmission is finished and then checks the channels.

SCAN MODE OPERATION

You can save channels into memory and then use scan mode to monitor those channels from lowest to highest. If the radio detects a signal on a channel, it stays on that channel as long as the signal is received; when the signal stops, the radio continues scanning.

Using the radio in scan mode

• To activate scan mode, press SCAN MEM.
• You must have at least two channels in memory to start a scan.
• To save a channel into memory, select the channel, then press and hold the SCAN MEM key. The MEM icon displays whenever you tune to that channel.
• To remove a channel from memory, set the radio to that channel, then press and hold the SCAN MEM key. The MEM icon no longer displays.
• When the radio stays on a channel, press or to leave that channel and resume scanning.
• To end the scan, press the SCAN MEM key again; the radio remains on the last scanned channel.

Scan mode with Weather Alert Watch

If you activate Weather Alert Watch while in scan mode (press and hold WX ALERT), the radio checks the most recently-used weather channel every seven seconds, then continues  scanning the next channel in memory:

Scan mode with Triple Watch

If you activate Triple Watch (press and hold 16/9 TRI) while operating in scan mode, the radio checks channels 9 and 16 every two seconds, then goes on to scan the next channel:

WEATHER MODE

The NOAA weather channels cooperate with the FCC to alert you of other hazards besides weather (child abduction alerts, nuclear, biological, etc.). In weather mode, the radio monitors one of the nine NOAA weather channels. If any type of alert is received, the radio sounds an alert tone and the display blinks.

Using the radio in weather mode

• You cannot transmit while in weather mode.
• To enter weather mode, press the WX ALERT key.
• If the radio setects a WX Alert signal, it sounds an alert tone 3 times.
• To turn off the radio’s alert tone, press any key.
• To cancel weather mode and return to the previous marine channel including emergency channels 16 and 9, press the WX ALERT key again. 

Weather mode with Weather Alert Watch

Because weather mode already monitors the weather channels, you don’t need Weather Alert Watch to check the weather channel every seven seconds. If you activate Weather Alert Watch while operating in weather mode, it operates as a type of “sleep” mode; the radio stays on the weather channel and mutes the speaker. If an alert is detected, the radio sounds an alert tone and turns the speaker back on. This mode is very useful when you are anchoring for the night but want to keep informed of hazards.

Weather mode with Triple Watch

If you activate Triple Watch while operating in weather mode, the radio checks the current marine channel, channels 9 and 16 every two seconds,
and the current WX channel about every nine seconds.

Emergency Channel 16/9

Triple Watch

Triple Watch mode monitors channels 16 and 9 for a signal while you listen to the currently-selected channel. The marine radio checks channel 16 and 9 for activity every 2 seconds.

1. Press and hold 16/9 TRI to activate Triple Watch. TRI displays.
2. Press and hold 16/9 TRI again to exit Triple Watch. TRI disappears.

DROP-OUT DELAY

While scanning, the radio stops on channels when it receives a signal. When the received signal is over, there is a drop-out delay of 2 seconds for the return of the signal. After 2 seconds, if the signal does not return, the radio resumes scanning.

BATTERY SAVE

This feature extends the battery life by switching the receiver circuit power on and off. Battery Save automatically activates during standby mode (RX mode without signal).

BACKLIGHTING

The Liquid Crystal Display (LCD) is backlit for easy viewing at night or in low light situations. Backlighting automatically switches on every time a key is pressed (except PTT and BOOST) and off 10 seconds after the last key is pressed.

1. Press the Backlight icon ( ) and the current backlight  level/color displays.
2. Press the icon again and the backlight level/color changes in the following order:
   White High (default) – White Medium – White Low – Amber High – Amber Medium – Amber Low – White High, etc.

ADJUST LCD CONTRAST

Adjust the LCD contrast to make the images on the LCD clearer and easier to see. You must first enter LCD contrast adjustment mode.

1. Turn off the radio, and then turn it on again while pressing and holding 16/9 TRI and WX ALERT.
2. Press VOL and VOL to change the levels (0 – 31). The contrast level displays and blinks.

KEYPAD LOCK

To prevent accidental entries, you can lock the keypad. Press and hold H/L LOCK until it beeps to activate Keypad Lock. LOCK displays on the LCD. When Keypad Lock is active, a warning beep sounds and LOCK blinks if you try to press any keys other than PTT, BOOST, or power.

The radio retains Keypad Lock status even when you cycle power on/off. To unlock the keypad, press and hold H/L LOCK again. LOCK disappears.

KEY BEEP

Key Beep is the tone that sounds when you press a key. To turn Key Beep on or off, press and hold the CH or CH key while turning the radio on.

When Key Beep is on, all key beeps are enabled. When Key Beep is off, all key beeps are disabled except WX Alert Tone.

SPEAKER VIBRATION TONE

If the radio falls overboard into the water, you can trigger a tone to help remove water through the speaker. This tone vibrates the speaker and helps push water out the drain hole and speaker openings. 

1. Press both VOL and VOL to activate this feature. The speaker vibrates and a tone sounds.
2. Press any key to turn off the tone.

MAINTENANCE & TROUBLESHOOTING

Due to its rugged design, your radio requires very little maintenance. However, it is a precision electronic instrument, so you should follow a few precautions:

• If the antenna has been damaged, do not transmit except in an emergency situation. Transmitting with a defective antenna may cause further radio damage.
• You are responsible for continued FCC technical compliance of your radio.
• You should arrange for periodic performance checks with your Uniden dealer.

MARITIME RADIO SERVICES OPERATION

Warning! This transmitter will operate on channels/frequencies that have restricted use in the United States. The channel assignments include frequencies assigned for exclusive use of the U.S. Coast Guard, use in Canada, and use in international waters. Operation on these frequencies without proper authorization is strictly forbidden. See page 28 for tables of the available channels and their uses.

If you are still not certain which channels to use, see the FCC maritime radio page at the FCC website (http://wireless.fcc.gov/marine/) or contact the FCC Call Center at 1-888-CALL-FCC. For individuals requiring a license, such as commercial users, you should obtain a license application from your nearest FCC field office (for US users) or Industry Canada (for Canadian users).

BASIC RADIO GUIDELINES

You should familiarize yourself with the rules on marine radios and be aware of which rules apply to your boat. Complete guidelines for all ship and marine radio types can be found at the US Coast Guard website under the topic Radio Info for Boaters (the direct link is: http://www.navcen.uscg.gov/marcomms/boater.htm). Here are a few guidelines that affect nearly all boaters:

• If you have a VHF radio on your boat, you must maintain a watch on channel 16 (156.800 MHz) whenever the radio is not being used to communicate. Starting in 2004, if a radio is carried, it must be on and set to channel 16 whenever your boat is underway.
• If you hear a distress call, wait a few minutes to let a shore station or Coast Guard vessel respond. If no other station has responded after 5 minutes, you must respond to the distress call. 
• Do not make false mayday or distress calls as a prank or to test your radio. (This is essentially like making a false 9-1-1 call; you may be subject to fines.)
