Re: MOTOROLA RADIUS GP900
Unprogrammed channels will have a constant tone. It is possible your radio is unprogrammed. A dead battery tone is only for a moment, and is usually a medium tone then a low tone, sounding somewhat like beeedeeep.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Technician (only for users in the US for now) and get all the help you need. Goodluck!

If the sound is continuous, like a long tone humming, it is possible you are on a channel which is not programmed. Try changing your channel knob to a different channel and see if the sound changes.
If the sound is not continous, and only happens upon pressing a button, we are not certain what you are experiencing without seeing the radio first hand.
If it were the battery you would get a low battery beep and then the radio would shut itself down. This can happen from a bad battery or a low battery. If this were the situation, you should check your charger and be certain the light comes on and stays on when the radio is placed on the charger. (Note: your radio should always be turned off when on the charger.) A quick test would be to swap the battery with a known good radio and see if you have the same problem. If so, you know it is not a battery or charging problem.
If none of these items help, send or bring the radio to a Motorola repair shop for a quick analysis.
GP300 radios will operate either radio-to-radio or in conjunction with a repeater. If your radio no longer works through a repeater, you might check to see if it will work in talk-around mode (radio-to-radio). Check with your repeater service provider to see if the repeater is in working order. One other item which might occur with a repeater would be if your radio is no longer recognized by serial number by the repeater. This is also something the service provider could help you with.
As you have all the transaction details, you will be able to do things, first of all, you need to contact the company/store you ordered them from and get a good reason for the delay. Secondly, if within a reasonable timeframe (2 weeks) you still haven't received your items, you can apply to the small claims court for a hearing, to try to retrieve your money.
It really depends on the charger. Does it do this for your brand-new batteries, or just the batteries that are more than 2 years old and, therefore, need to be replaced? If it's happening to a brand-new battery, then maybe you're trying to use a nickel-cadmium battery charger for lithium-ion batteries or for nickel-metal hydride batteries, and you're dealing with a chemistry problem which requires Ni-CD batteries or which requires a newer charger.
The best price I found for your batteries is on eBay. Here's a link to a current listing: http://cgi.ebay.com/Battery-MOTOROLA-Radius-GP300-GP388-LTS2000-HNN9628-/290428070271?pt=LH_DefaultDomain_0&hash=item439edca97f
The GM300 is dealer programmable using Motorola proprietary software, a programming cable and radio interface box (rib). (Or on some models a ribless cable). I will continue to look for a user guide pdf. If I locate one I will post it.
No user manual available, GP900 is a European version of HT1000 here in the US. Basically, on the top of radio on/off volume control is on the left, next to it is a channel selector, 3 position ABC toggle switch and orange button for emergency. On a side are button 1,2,3 and PTT switch. Hope that will help.
The Motorola GP300 needs an external device to program the frequencies assigned to the channels. All other features and functions are also accessed (enable/disabled) in the same fashion.
To start with, you would need programing interface that attaches to the back of the unit once the battery is removed. This also provides the power to the radio as well as the data connections. The interface is called a Radio Interface Box (RIB). Aside from the power leads, it has also a multi wire cable that is terminated with either a 9pin or 25pin serial plug that plugs in to the serial port of a PC.
Likewise required is a specific Radio Service Software (RSS) package(s) that is appropriate for a Motorola Radius GP series. This should be run on a personal computer capable of running pure DOS.
On running the RSS, all parameters can be adjusted and configured to your preference like Ch1 to be set to 456.789 MHz, CTCSS 108, etc. Having said this, then it is just a matter of repeating the programming to all of your radios.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
