My emerson 228 is flashing blue and red and I know it needs to be charged but when I plug it in it turns red for charging and then 2 seconds later the red light goes off and no charge I tried two different chargers still won't charge!!

first are you now using li batteries or nicad batteries
small chargers are battery composition specific
secondly-- chargers for aa /aaa batteries are cheap so get a new charger for the batteries in use

It is common for many Braun shavers, that if the indicator light flashes red while the shaver is being used (switched on and running), it means the battery is low and needs to be charged soon.

Below is an example from a manual for a Braun model 7526 shaver. You can search that site for other manuals if this is not the correct one.

This model shaver has 3 indicator lights:
1) Green (Charging)
2) Red (Low battery)
3) Blue (Power cord attached and plugged into the wall)

Download the manual for the model 7526 here: http://www.manualslib.com/manual/20281/Braun-5301.html#manual

"The green charging light shows that the
shaver is being charged. When the rechargeable
battery is fully charged, the charging light
flashes or goes off.

If later on, the charging light comes on
again, this indicates that the shaver is
being recharged to maintain its full
capacity.

The red low-charge light flashes when the
battery capacity has dropped below 20%,
provided the shaver is switched on. The
remaining capacity will then be sufficient
for 2 to 3 shaves."

1. Charge the headset:Headset is charged via USB cable, the light will be red when charging. When the battery is fully charged (about 2-3 hours), the red light of the headset will turn off automatically or the red light turns blue.
2. Turn on the headset:Press the on / talk button on the headset for about 5 seconds until the blue and red flashes alternately (or blue flashes or the blue lights all the time ), now the headset is ready to be connected to the iPhone.
3. Go to Settings, and tap Bluetooth. Turn on Bluetooth.
iPhone will automatically start searching for Bluetooth devices. Tap the device in the Devices list, then follow the onscreen instructions to connect to it. After matching successfully, the blue light on the headset will flash twice per time.
4. Call: when you finish all the above steps, you are going to talk via the Bluetooth headset. When there is incoming call, press the on / talk button, you can talk with Bluetooth headset, when you want to end the call, press the on / talk button, you can end the call.
5. Turn off the headset: Press the on / talk button for 5 seconds until the red light of the headset flashes quickly for twice, then release the button, the headset will be turned off.

Hi, Ephraim. The flashing red light indicates that the device is showing "low battery". It could be that the LG phone charger fits the charging port on your bluetooth headset but it is not compatible with your device. In order for you to know that it is charging, the device should show a steady red light(means charging).
Please take a look at the table reference below.

Well... I've got the n65, and this is the third time I've gone to charge it. Solid red, won't turn on no matter how long its been plugged in, can't find the manual, this fixya page is the best result online...so my solution is to stop by the local cell-phone accessory shop to buy something new.*
*Results may vary. :^s

I have the same problem? some can help us ?

Move the call control button up or down, the indicator light will flash blue if it's paired or blue and red. If it flashes blue and red you need to pair phone with the headset. the passkey is 0000.

Pardon me if you have already tried this but with my em236c I had to hold the Answer/End button for about 15 sec before it flashed red/blue. The manual doesn't say how long to hold it. It took a couple of tries for me. Hope this helps.
