How to Find a Max Load for the Radio

Look at page 4: Power and battery drain.

I am back again :-) but different question

I am pasting below part of an attached doc of page 4, I googled each term for their meanings, but I don't understand how to involve those terms in my circuit design, as indicated with green arrows shown below

Insufficient information.

Which control head do you have. If it is the 07, you have a high power radio.

If you can legally own and use this radio, you may want to look here:

APX Mobile O2, O3, O5, O7 & O9 Control Head Installation ...

This radio may require a special license to operate.

I'd have a licensed radio technician install it.

I'm not sure any further help is warranted for an anonymous poster.

Thanks for attaching the document, and according to the page 15 of the model part number, the position 5 is for power level. Is that the power used for finding the fuse size. Should I divide that power level by 12 volt, or there are certain calculations to find out the max current for the radio.

RTFM!

This is difficult with a, probably, stolen radio. This is a 800 MHz trunked "Public Service" radio that requires software to program it. I recommend not communicating with this individual, again.

you need to be careful when communicating, submitting this type of comment, lies, and accusing people. I am working for this public service, and I am doing wiring installing for this service. It is part of my job. I ask you of not be a fool submitting this type of comments before making some type of approve. I was requiring some help for doing my job, I am new for those thing, and there were individuals who were useless without providing any help but made some type of stupid comments.

You are installing public service radios and don't have a clue what you are doing?????????

That is unbelievable.

YES I AM NEW FOR THIS JOB AND NO ONE AROUND TO HELP. I read the manual but there are things are new to me and I should be careful because it is for public service, so I should make it work. I had done lights but not radios

You better stick to the lights then. Or start reading the installation guide as already suggested.

Is the public service making those people or are those people having an impact on public services?

Please consider the information provided.

In my experience, Motorola, General Electric, Yeasu, and others supply a "complete" wiring harness with their respective unit. This includes fused B+.

You, apparently, have a "incomplete" wiring harness that "may" have been removed from an, otherwise, operational vehicle; possibly a motorcycle.

If, and I say "if," you indeed work for a Department of Public Service, and this is a legitimate inquiry, then I recommend that you look at another vehicle with a similar installation.

Then why do you post Anonymously?

Its obvious to many here that you are trying to do something illegal and do not want to be known by your logon name (as I believe that APs are all members nowadays!).

We will see what happens to this blog once someone reports you for illegal activities.....

whether I shown my logon name or being anonymously, it does not matter to everyone, I have not asked something was illegal, but only general information that engineers would understand, and those who their specialty in communication system. I was wrong to post in this side, I thought this site is for engineering people, but upon most replies they are not engineers, but people lacking of knowledge. usually someone who does not understand makes such stupid comments, and it looks like they have so much time to spent in this site plus other sites, useless people.

YOU'VE BEEN CAUGHT OUT!!!

IT'S OBVIOUS.......

I HAVE TO LAUGH......AGAIN AND AGAIN AND AGAIN.....

You need to learn "WHEN TO POST" AND "WHEN NOT TO POST!" AND "WHAT TO POST!"

Otherwise it simply makes you look dumb!!!

Goodbye!!

you could keep laughing and laughing till you die. If I am dumb, then why you read dumb posts unless you are worse than dumb people. At my work area, there people using this type of language similar to yours when they are unconfident in themselves, or they lack understanding. My advice to you, don't spent time over sites reading every individual post, try to make some benefit to your life and to people around you.

Goodbye forever.

is that a promise?

I have seldom read a post here SO COMPLETELY WRONG!!

You really are weirdly funny.....and no more intelligent than I thought before, maybe even less so!!!

Obviously you have either not been very long on CR4, or we have not co-posted on the same blog, because otherwise you would not post so much stupid crap!!!!!

ASK ANYONE HERE!!!

(But please continue as long as you wish, its like watching a clown at the circus, quite funny in a sad sort of way!!)

ok it is stupid crap question, don't force yourself reading those type of posts, just move to the next one without wasting your time.

Hopefully others could benefit one thing out of you.. Good I make you laugh so much, and just keep laughing and laughing and laughing, just keep spinning on your chair and laughing

Come out of hiding! Tell us all who you are!!

It will make us ALL laugh even louder than right now maybe!!!

But being "chicken" is what you are, with a dollup of yellow on the back side?

So I cannot believe you will ever get up the courage to do it!!

But you would then at least, prove me wrong at once in this whole stupid blog you started?

So how's about it my lad? Get one thing right at least!!!

Most people who respond on this site are professionals or retired professionals who have better things to do than someones job for them.

Upon the answers, they don't look professionals. Usually professional person provide good directions, and they don't making jokes in their answers or making some stupid answers.

What part of my post indicated that I am seeking someone to do my work. Read it very well. All I asked the term of max load to calculate my breaker size, how to read it from data sheet, and you made it such a big story, and no one so far had provided me a good answer.

So you say, but did you actually read the installation guide?

There was a story with a man and a gun and a bear.

The end of the story was that the man apparently did not go into the forest for hunting.

You remind me of that guy.

You measure the max load.

If you read through the installation manual you will see ample information about fuse size and where they go.

Lyn provided you with everything you need to answer the question.

I guess its reading time for you now.

The fuse is there to protect the wiring. You do know that, don't you? THE WIRING!

Are you asking about the line fuse? All my mobiles have a line fuse (25A usually) on both the positive and negative 13.8V DC feed lines.

I have a supplied manufacture fuse that is within the wire(it is already built into the wire when received from manufacturing), but beside that fuse which is to protect the device itself, I wanted a circuit breaker value that would be on the main breaker panel. I was looking to the value of max load of the radio and from that value I could find the size of the breaker.

Are you considering connecting the wire with the incorporated fuse into an AC distribution board?

BTW that fuse in the wire protects the wire not the device.

If you know the current rating of the line fuse, then, clearly, the radio can't draw more current than the fuse will allow. Use this to size your breaker. As pointed out, the fuse is there to protect the wire and current source from overloads, not the load.

why dont you pick up the phone and call the manufacturer?

surely they will know the information you require if this is actually a legitamite installation and you have purchased the radio from them?

Usually I call manufacturer when I have some misunderstanding, and all manufacturers are very helpful in supporting, but Motorola is the worse service I ever I had so far. they never reply.

They never reply or they never answer the phone?

..they never use their brain either!!!

100 Ampere Slow-Blow should do the trick.

Anonymous Poster,

I posted the ACTUAL MOTOROLA INSTALLATION MANUAL for you.

If you are incapable of understanding the contents, get a donkey!

With a donkey you won't even need to know where to insert the ignition key.

You are not capable of performing the rudimentary installation of this radio, even after being presented with the installation manual.

Now, stay true to your word and say goodbye, forever.

In order to get an answer read the questions that you were asked and answer them first.

Your original question did not give enough information to provide you with any reliable help.

Ignore the postings that mock, they're a joke, laugh along maybe, but don't bite back.

Now, Where is this breaker located? Have you read the manual yet?
