There is no "flash." The infrared glows a dull red. In pitch dark or quite dark conditions an observant person might notice the dull red square.

The red light blinking is low toner indicator. Make sure you removed the paper strip.

Ours actually shows a flashing red light when the battery is getting low, just on the receiver, little red light starts to flash.

Don't quote me on this, but I think red means the device is grounded. So you do want both lights on.

Red Light means charging, and off means charged....that simple. Amber is only when it's on.

The on light flashes when it has been triggered. Whether once or 20 times, you can't tell.

The red light is supposed to blink constantly. If it isn't blinking, send it back.

The instruction booklet states there will be a lag time between entering your code & the door unlocking when the battery is getting low. That's supposed to be your sign to change the battery. I didn't see anything about a red flashing light, but I could have skipped over that. It's a pretty short manual, tho! lol

The red light indicates that a flash is needed when you pre-focus and hear the beep sound. You will notice that in bright light, the red light does not come on with the pre-focus beep because a flash is not required. I am not sure that you can disable the red light, as it is for indicating that a flash is required. Maybe if you set the manual (M) mode in a certain way the red light will not go on and you can override it, but that is beyond my knowledge. The red light basically indicates that the lighting conditions require a flash. Maybe someone else can provide you with a more technical answer, but hope this helps you somewhat with your questions.

The light flashes as it is charging. It will stop flashing and have 3 solid lights when fully charged.

Blinking red light means it is charging. Solid red light means it needs charging.

The warning lights are red. There are three white LEDs that can be used as a flashlight.

The red light flashes to indicate low batteries. I'd try taking them out and reinserting or use a different set altogether.

when red and green flash alternating, it means "charging is not possible".Either the terminals are bad or most likely, the battery is bad, and won't take a charge.I overcharged a battery with another type charger and my new charger confirmed it. the new battery I bought with the charger works perfect.
