Batboard

Hi there,
I have a CP040 (CP150/CP200) which when turned on make no sound. It only shows a continuous orange LED. (Red and green LEDs lit) Has anyone got a solution or perhaps aware of what causes this fault?
Many thanks in advance.

low power going to microprocessor.. either low battery or a swimmer radio

Thanks for that, but not a swimmer or low battery.

Can you read with CPS? Does it transmit? Ever receive a transmission on it? Smells like a corrupt codeplug or a bad EEPROM

Hi there,
no code plug read. I also have a number of UHF CP040 radios that when switched on they give about a 1 second red LED flash followed by a short low tone. If the volume is then turned up you can hear some audio hiss in the speaker. Any idea's. Many thanks for your reesponses.

What do you mean by no code plug read? You have not yet read the codeplug, or you're unable to read the codeplug?

Again, it smells like a corrupt codeplug problem.

I don't suppose you are using NiCD batteries with these radios????

Try reading the radio, but it sounds like a response to a QCII call alert.
My CP200 responds to a call alert in this very manner.

I suggest you read the codeplug, and find out what options the radio is capable of.

That's an almost guaranteed corrupted codeplug. I don't know about the CP040 models, but the CPS for the CP150/200 series can detect a corrupted codeplug & will attempt to fix it. If that fails, a firmware upgrade will almost surely fix it.
