SOURCE: GP 360 Radio Charger

On a Motorola charger, when the battery is charging the light should be a constant red (or amber depending on the charger). When the charge cycle is complete the light will change to solid green. Sometimes the solid green time is brief, as the battery will begin to lose charge, and the charger will go back into trickle mode and change once again to red (or amber). In most cases, a flashing light indicates a problem, such as a bad or shorted battery, an incorrectly seated battery, dirty battery contacts, or a bad connection with the battery. (Note: Batteries last 18-24 months typically. Check your date code for the age of the battery.)

There were several chargers made for the GP360, including but not limited to a 60-minute charger, a 90-minute charger, a 10-hour trickle charger and a 6-unit gang charger which would be a rapid rate, either 60- or 90- minute. If you would supply your charger's model number we could tell you which one you have.

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.

Continuous green light at GP-2000 and hissing sound from speaker


Have you adjusted squelch threshold. Green light indicated signal received with noise, squelch will adjust the threshold so light goes off except when a stronger signal is detected.

Green led on , but no sound when speaking through microphone


Sounds like an attempted amp/PA mixer repair to me. Plug a guitar or music source into one of the inputs and see if you hear anything. Honestly, the protection relay circuits rarely go bad but instead are reacting to problems elsewhere in the circuitry. Good luck.

I have a Motorola MR350 and have been using the pair for several months now. I must say, the coverage is pretty good and I really enjoy the design. However, last night when I turned it on, the user on...


It is possible you have one rechargeable battery pack getting weak. Try swapping the batteries, and see if the problem leaves, or changes to the other radio. Typically when batteries start to go bad a common sign is hiss, static, no transmit, or intermittent transmit.

If you do find it is a battery problem, then check your chargers. You could have one charger causing the problem, or simply dust/debris on the charge contacts. This can happen from hand oils getting on the contacts, and then over time dust accumulates and creates a barrier between the charger and the radio. These can be cleaned with a pencil eraser.

Always be certain the radios are turned off when on the charger.

If the battery and/or charging set up is not the problem, then you have a radio problem. If it is the radio, you will likely need to replace it. Parts and schematics are not available for this model.

Best regards.

I have a motorola AP-300 which keeps on blinking amber light when i turn it on. how can i reset it or what's wrong with the AP?


From the installation guide for this AP, I find the following:

LED Indicators

The unit has LED activity indicators on the front of the case provide a status display indicating error conditions, transmission, and network activity for the 802.11a (amber) radio or the 802.11b/g (green) radio.


802.11a Activity LED Amber

The amber LED flashes three times per second until firmware is loaded. During boot, 802.11a mobiles cannot associate. After adoption, the amber LED is steady or flashes with 802.11a radio traffic.

The amber LED flashes once per second if an error prevents the 802.11a radio from operating normally.


802.11b/g Activity LED Green

The green LED flashes three times per second until firmware is loaded. During boot, 802.11b/g mobiles cannot associate. After adoption, the green LED is steady or flashes with 802.11b/g radio traffic.

The green LED flashes once per second if an error prevents the 802.11b/g radio from operating normally.


From this, it appears that the 802.11A radio is malfunctioning.


Here is the Motorola support web page for this device.

Hissing from computer speakers and they are new


Hello
A hissing sound indicates the speaker amplifier has no input from the computer sound card, check to make sure the speakers are hooked up to the correct port for audio out to the speaker input, the Audio output to the speaker is the GREEN mini RCA jack on the back of the computer.

Problem in ppi pcx-2400


Check the amplifiers fuses. Some amps have speaker fuses that leave the LED on if blown. Check for continuity on the voice coils of both subs. Check for 12 volts on the remote turn on line from your receiver. If all of the above are good, the amp is probably toast.
