My O2 Atom on normal mode binks in blue colour and there is a missed call or sms blinks in orange (or red). from yesterday it blinks in green on normal mode. Can you please tell me why? Anything wrong?


The notification lights indicate:
Blinking Blue - Bluetooth On
Blinking Yellow - WiFi On
Blinking Green - GSM (Phone) On
Blinking Red - Unread message
Continuous Red - Charging

Blinking green when your GSM (phone) is on is the expected behavior.

My palm centro will not turn on the red light just blinks and occationally it does come on


Hello abevagota25,

A flashing red indicator light (upper left-hand corner) occurs when the Centro is connecting to the the cell phone network. The light will continue to blink until it gets a strong enough signal to make a good connection. Try turning the phone on from different locations to see which one makes a good connection

If this solution is helpful please click a thumbs-up rating below.

Have a great day,

I can't get my jawbone to pair with my palm centro any idea's


With the jawbone turned off, press at the same time the turn on button and the noise reduction button. The jawbone should blink white and red for three minutes, in that time you shoul be able to find it as a bluetooth device in the free hnd configuration of the palm centro. than yu complete the conection by inserting the code. The next time you turn on the jawbone it will connect with te palm.

Red blinking light


On certain models the blinking red light means you have a message. On others it is because you don't have service.

If yours has service and it is not blinking I would wait to see if it starts blinking when you get an email or message of some type.

Light keep blinking


The Palm OS does 'housekeeping chores', one of which is to tell all of the apps about certain events in case they need to do something during one of those events, even the one on the HD.
