Speaker light is blinking because the phone was unplugged momentarily

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices....

Blinking WiFi light indicates that the printer is either trying to connect to a wireless network or not at all. Unplug the printer from the power outlet. Replug after 10 seconds. This will give enough time for the printer to reset. If WiFi light continues to blink, you may need to reset the printer's wireless network adapter. Please refer to this article: How to Reset the Z1400 and Z1500 Series Network Settings. The WiFi light will then turn off momentarily, then lights up solid orange. Launch the Lexmark Wireless Setup Utility to reconnect printer to your wireless network.

Sounds like you might have accidently set call forwarding up. To cancel call forwarding, with the handset down in the cradle press #11.

First thing to try is to pick up handset or place on speaker. On the answer machine itself without trying to call your cable providers voice mail service...press the message button to ensure all messages have been heard or erased.
Second, unplug your phone power from the wall and wait two minutes before powering on the phone.
Last replace batteries in the phone if you have batteries in the phone now...may be low battery signal.

From the manual:
Resetting the Router
Push and release the “Reset” button. The lights on the
Router will momentarily flash. The Power/Ready light will
begin to blink. When the Power/Ready light becomes solid
again, the reset is complete.
b. Restoring the Factory Defaults
Press and hold the “Reset” button for at least 10 seconds,
then release it. The lights on the Router will momentarily
flash. The Power/Ready light will begin to blink. When the
Power/Ready light becomes solid again, the restore
is complete.

try to unplug and then plug again all the speaker's connections...make sure you do the right connections...or get a AA or AAA size battery,put the + side of battery to the + of speaker(alone/unplug),and momentarily touch the negative(-) side of battery to the negative(-) of your speaker,,you must hear a click from your speaker...if there's no click,you have a defective speaker..

I would unplug the power to the router, and go through the steps to reinstall the router drivers..what should blink is the internet light and the port that you are using....

The blinking light on the speaker button means the forward when busy is on. To cancel it- With the handset on-hook dial #12.
Then press your own station number. Then dial # again. The speaker button should stop flickering.
Note: If the SPK button continues to flicker, Forward all is activated. It is the same process as above but use #11 instead of #12

I have the same problem. After about 2 seconds the system status light blinks red and the system needs to be reset. The only way to turn the system on is to unplug from power for 5 minutes and then plug back in, wait for light to stop blinking and then turn on. I have cleaned the filter on the left side. The model is Mitsubishi WD-62725. any ideas?
