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.

Volume trouble


The top button on the control surface, the one with the green flashing LED, is the volume control. When the unit is "ON" pushing the button up or down raises or lowers the volume, simple. When you connect it to the charger that same green light will turn red while charging. If you push the top button forward (up) at the same time you press the lower button (power) the LED will flash 1-3 times. Three flashes is fully charged and one means it's getting low.

This is a great head set. I just sat on mine and broke the ear piece. I'm looking for another as we speak! It's worth more than it's current retail price by far!!!

Samsung DLP HL-S5087W 56" Confused...


Mine did that when the color wheel didn't spin up...just give it a whack where you installed the light & the wheel should spin up. I had to replace my color wheel as the bearing was shot & was buzzing all the time. The light won't come on if the wheel doesn't spin up first.
