Does anyone have a manual for the Standard Horizon Maxi marine radio

Thank, but I have managed to get manual on engine

You can't "select" channel 70, nor can you talk on channel 70. Channel 70 is reserved for the exchange of digital data between radios.

And it is not possible to address an "emergency" (do you mean distress? or urgency?) message to an individual recipient.

Your radio is not allowing you to do any of these things because it has been (correctly) programmed to discourage you from doing things that would be illegal.

If you set up a routine call with your friend (or anyone else), you should find that once the two radios have completed their (almost instantaneous) exchange on Channel 70, they will both switch to whichever working channel you had selected, and he will get a beeping sound to tell him that there is an incoming call.

Sounds to me like both radios are doing exactly what they are supposed to.

Yes, the yellow wire is the switched hot lead - it is typically connected in one way or another to the ignition switch. There is also a smaller gauge red wire that is connected directly to the battery (through a fuse of course). Both of these wires have to have power for the radio to work. Also the black wire has to be connected to a good ground. If all three of these wires are confirmed to be in good order (power where there should be power, ground where there should be ground and no shorts) the radio should at least power up when they are all hooked up and the ignition is on.

You should try this instead. http://www.smartplug.com/
They know the standard and I have used them without incident since they came out. Not a bad way of doing things!

• By no power do you mean you get no response from CD or radio out of the speakers when trying to use the radio? Should this be the case then I'd like you to check a few places.

1. First look to make sure the wires in the back are not broke or the insulation has somehow been negated.
2. Next is to check the power wires and ground wire. Look for an inline fuse anywhere between the battery and either power wires. One should always be installed to prevent a surge reaching the head unit so make sure to check for a fuse. Replace if blown with same size fuse, never bigger.
3. Remove the face plate and notice the reset hole (last hole on the left) Take a pen or other pointed but not sharp item and stick it into that hole and hold for 10 seconded. Then retry.
4. Make sure the contacts for the face plate where it hooks into the head unit are clean and don't have any grime buildup that would prevent any of the contacts from contacting.
5. Next you can try removing all power wires and wait for 5 minutes and re-connect. Sometimes this will also reset the unit.

• I know you asked for a manual. I don't have the exact one. I do have a similar one that I can offer. http://www.premiumleisure.com/Manuals/nov07/Hydro_Spa_JBL_Stereo.pdf
• Your unit was discontinued and not made for long and this may be a part of why the manual is difficult to find... for free anyway it is. I can say I don't need a manual to help you determine why the unit is not powering on.
• How are you determining has power but just not responding to the on/off button? A volt meter check to the wires perhaps at the back of the radio? If you get power to the wires at the back of the radio then double check your ground real well because if the ground is good then, at that point, the head unit is bad.
• If you perform all the tests I stated above and still no dice then the head unit is bad. There is no "code" for the radio so that will not be a factor. It's really a process of elimination.

• Hope this helps and thank you for using FixYa.
