check the connection inside the radio, switch of AC-DC connector maybe loose contact.( leak diode more probability replace it)

Good morning ,
It happened with me one time after i left the long time fixed on the board , and it disappeared without doing any thing ,
don't worry

when orange light is on it means it is charging and to know whether your system is charging just look at battery symbol where you will find a wire symbol on battery which show it is charging and when charge is complete orange light turns blue

It could be the charger, the phone's power interface, or your battery. When you plug the phone in to charge it, does it recognize the charger and show the lightning bolt symbol for charging?

If you use your computer's USB port to charge it instead of the wall charger, does it act any differently?

Digital red symbol of the head shows up. It's menas that you should change new replacement heads, that Norelco Arcitec electric shaver replacement heads is Norelco RQ10 shaving heads.

I had the same problem with my ZR800. After lots of searching on the net I found out what the symbol indicates. It means that the little battery that holds the memory for the clock is weak. It's under a little cover behind the main battery compartment. I put in a new one that the flashing icon is gone. I put the battery I took out into another ZR800 and the icon started flashing on it. A simple solution that Canon should have posted in the manual.

maybe the batteries are old? i had this problem once. i just bought new ones.

if you remove the battery and replace it back into the phone does it reboot?
You may just have a bad battery.

you are screwed

hello,

normally many cell phones requires 6-10hrs for its batter to fully charge up. also i have seen it where battery can be brand new but doesn't have enough juice to hold the charge.
now as far as red light on charger, remember even if you have 99% charged batter and you plug in the charger it will show you red light on phone/cradle.

FYI- all brand new phones are covered with 30 days of warranty replacement with new phone. after 30 days it covers upto 1 year from the date of purchase with refurbished phones.

In your case i think it is just the battery, try having your provider replacing new battery if no luck again then my suggestion will be to replace your phone with new battery with in 30 days.

TY
