How do I connect my GPS to the radio?

Below is a list that shows Manufacturers GPS and connections to the QUEST. The QUEST is supplied with an accessory cable that will allow connections. The QUEST is looking for GLL, RMB or RMC sentences in NMEA Version 2.0 or higher. The Baud rate should be set to 4800 and If there is a selection for parity select none.

My radio display blinks every time I transmit on high power.

Possible antenna problem or antenna maybe mounted too close to the VHF.

Temporarily connect the radio to another VHF antenna that is working properly to verify the problem.

If the radio is not operating, send the radio to the STANDARD HORIZON repair department: 10900 Walker Street Cypress, CA 90630 Phone: 800/366-4566.

If the radio is working properly make sure antenna connector is soldered properly and is not corroded. Also check the fiberglass of the antenna to ensure there are no cracks that could of allowed water to get inside.

How do I check to make sure my MMSI has been entered correctly?

It is possible to view your MMSI number to make sure it is programmed correctly. Press and hold the CALL SET key to activate the setup menu. Scroll down and select USER MMSI by pressing the CALL SET key, check to see if the MMSI is correct. At this point do not attempt to change the numbers unless they are not correct, doing so will count as a second attempt at user MMSI input. To exit, press the 16/9 key.

What should I do if I get the message "error too many entries press the CALL/SET key"?

If you attempt to enter the MMSI more than 2 times the unit will not allow you to enter your MMSI number. This is a factory setting to prevent misuse of unauthorized MMSI numbers. To reset the unit you must send it in to the factory service center: Standard Horizon Attention Marine Repairs 10900 Walker Street Cypress, CA 90630

The party that I am transmitting to advises that my voice is weak.

The QUEST speaker microphone has Noise Canceling trade name (clear Voice). This mic works by canceling the noise so it is very important the when using the mic to speak directly into the hole located on the lower front part of the mic with your mouth about 1 inch away.

What is DSC all about?

Digital Selective Calling (DSC)

DSC is a semi-automated method of establishing a radio call, it has been designated by the International Maritime Organization (IMO) as an international standard for establishing VHF, MF and HF radio calls. It had also been designated as part of the Global Maritime Distress and Safety System (GMDSS). It is planned that DSC will eventually replace aural watches on distress frequencies and will be used to announce routine and urgent maritime safety information broadcasts.

This new system will allow mariners to instantly send a distress call with GPS position (when connected to the transceiver) to the US Coast Guard and other vessels within range of the transmission. DSC will also allow mariners to initiate or receive distress, Urgency, Safety routine, POS Request, POS Send and Group calls to or from another vessel equipped with a DSC transceiver.

USCG DSC Watch

The USCG has plans to upgrade its VHF National Distress System (expected by 2005), so at the time of printing only larger vessels that are required to carry VHF DSC radios, other boater with VHF DSC radios and most towing companies will be able to hear your distress transmission

Maritime Mobile Service Identity (MMSI)

What is an MMSI?

An MMSI is a nine digit number used on Marine Transceiver capable of using Digital Selective Calling (DSC). This number is used like a telephone number to selectively call other vessels.

How can I obtain an MMSI assignment?

style="mso-spacerun: yes"> Boat US is offering MMSI free MMSI numbers. Visit the following to register: http://www.boatus.com/mmsi/.

style="mso-spacerun: yes"> 

style="mso-spacerun: yes">Distress Call

Transmits a DSC Distress message to all radios equipped to receive a DSC Distress call. Some Standard Horizon radios may be connected to a GPS to also transmit the Latitude, Longitude of the vessel.

Individual Call

This feature allows the user to contact another vessel capable of using DSC and automatically switch the radio to a desired working channel. This feature is similar to calling a desired vessel on CH16 and requesting them to go to another channel.

Urgency Call

This call should be used when a vessel may not be truly in distress, but have a potential problem that might lead to a distress situation.

Safety Call

Used to transmit boating safety information to other vessels. This message usually contains information about an overdue boat, a derelict afloat, loss of a navigation aid or an important meteorological message.

POSITION REQUEST

Advancements in DSC have made it possible to poll the location of another vessel and show the position of that vessel on the display some Standard Horizon VHF's. Standard Horizon has taken this feature one step further, if any Standard Horizon GPS is connected a Standard Horizon VHF with this function the polled position of the vessel is shown on the display of the GPS chart plotter making it easy to navigate to the location of the polled vessel. This is a great feature for anyone wanting to know the position of anther vessel for example you buddy that is catching fish, or finding the location of a person you are cruising with.

POSITION SEND

The feature is similar to Position Request, however instead of requesting a position of another vessel this function allows you to send you position to another vessel. Your vessel must have an operating GPS receiver connected style="mso-spacerun: yes"> the a Compatible Standard Horizon VHF to send the position

When other vessel receives your position, the transceiver outputs the position to aany Standard Horizon GPS chart plotter to show your position on the receiving transceiver.

CALL WAITING DIRECTORY

The DSC Call Waiting directory logs received distress individual calls that are received and not answered within 5 minutes or while the radio is set on the DSC Standby function. Calls will be logged while busy with other communications as long as the transmitter is not keyed at the time of the call. If the call is answered within 5 minutes the call will not be logged. When a call is logged, a message will appear on the LCD.

 

ADDITIONAL DIGITAL SELECTIVE CALLING INFORMATION

For additional information the USCG has an excellent site that should be visited at www.navcen.uscg.mil/marcoms/gmdss/dsc.html.

  

 

 

What IS JIS7 submersible rating mean?

JIS stands for Japanese Industrial Standards. Level 7 is a submersible rating. The QUEST can withstand being submersed for 30 minutes. We all know that if this actually happens, you have bigger problems than your VHF, but the main jest of this test is to make sure the radio can withstand being mounted on a VERY wet boat.

Is there a flush mount kit available for this radio?

This radio can be flush mounted using the optional CMB16 flush mount kit available through any of our Standard Horizon dealer or parts department at (714)527-1716.

DIGITAL SELECTIVE CALLING

The QUEST meets the requirements for RTCM SC-101 Digital Selective Calling. The DSC DISTRESS function when activated transmits a digital MAYDAY including vessel identification, Latitude / Longitude and time (with GPS connected), to facilitate prompt response. Additional calls that can be made are Individual, Urgency and Safety and Position Request (No NMEA output).

GPS REPEATABILITY

When connected to a GPS receiver the QUEST repeats Latitude and Longitude along with date and time on the radio display. This is a handy way of knowing you position when the radio and GPS are at different locations.

OVERSIZED CHANNEL NUMBERS

Visibility is enhanced with tall and wide channel numbers and obvious information flags that are easy to identify. The LCD and keypad feature 3-step backlighting and 7 steps of LCD contrast adjustment.

CLEAR VOICE NOISE REDUCTION TECHNOLOGY

The QUEST features Clear Voice Noise Reduction Technology eliminating unwanted background noises like engines and wind during transmission. This assures transmissions are crystal clear along with dedicated 16/9 key and channel selection.

ADDITIONAL FEATURES

The QUEST also features a spring loaded DSC Distress cover, channel naming capability, dual watch, user selectable Scan and Priority Scan, NOAA weather channels with alert, and improved speaker audio Dual Watch, user selectable Scan/Priority scan and NOAA Weather channels with alert.

3-YEAR WATERPROOF WARRANTY

If the QUEST fails for any reason (including water damage) during normal use for the first 3 years of ownership, STANDARD HORIZON will repair or replace it free, without hassles or charges. If it fails for anytime thereafter in normal use, for as long as the original purchaser owns the radio, STANDARD HORIZON's Lifetime Flat Rate and Customer Loyalty Service Programs will cover it.
