I want a plug-in with a calibrating screen but NO batteries. does such a thing exist? would this chirp non-stop if i leave battery out?

Well, the First Alert C0600 is a plug in type with no battery but there is no calibrating screen. The C0615 you are looking at here will chirp if you leave the batteries out of it. You may want to check with your local municipality before you buy this though. Some areas require a battery backup to these types of alarms or they won't pass code.

Mine works great and always has. The fact that a display cycles probably means that you have it hooked up wrong. In normal operation, one bar stays lit or flashes when low. Remember that the positive and negative have to ALWAYS be hooked up to your battery pos. and neg. I've got a switch on mine to turn off the display but it's not really needed. One user says "The C is for your switch to turn on the indicator, with my application, I ran a wire and connected it directly with the positive terminal for the indicator, beings I want to be able to kill power to the entire indicator when not in use. Prolly wasn't needed but that was my choice and it works great. The R is unused and I think I read that it's not commonly used." On mine, I think that means that when I installed it I hooked pos to battery pos and neg to battery neg. Then I hooked a wire from C to my switch and back from the positive pole on my switch to neg on the indicator. If you don't put in a switch, then I believe C just gets hooked straight to positive so that the unit will display.

Can't find a way to check the charge level manually. Saw a 5 bar meter during startup once at 2 bars but it rolls through it automatically. What I go by is the unit will not brighten the screen when the level is low and it gives a warning message to that effect. You can change out the batteries without losing data on the round. I am not using rechargeable batteries at this time so I just carry a couple spares and change when needed. I seem to be getting at least 10 hours on a pair or 2 rounds.

The monitor in the baby's room can be plugged in. It does not need batteries to work. In fact both units have AC adapters. Either can be plugged in or use batteries. I always leave the baby monitor (microphone) unit plugged in under my baby's crib. The parent unit (speaker) is plugged in when next to my bed at night, but I use the batteries when I am awake and carrying it with me.

You only need batteries to run the screen of your time and calories. But it does come with a wall plug.

No, it uses batteries. You will, however, not be happy with the display. Mike

It does work when it's plugged in, just kind of annoying and it recommends not to. But I have before haha. There is no battery indicator light either which is kind of odd, so you kind of just hope it lasts or that it's charging. Haven't had any problems about it not charging but its still strange.

I find my monitor calibrating every now and then, flashing various colors and lines across the screen, but it usually doesn't look for input. I'm guessing it's getting a mixed signal from your computer, or some device it is plugged into? If you hit the "Source" button (the + sign), you can select a default source and turn OFF the auto-select source option. This might also help.

Power cord and head phones if you are using. Can be used without any cords on battery. The screen is attached but the unit could be hooked up to a TV also.

I don't think so. The software locates it via wifi so you would need to be within range. There might be another way but someone else would have to explain. And. If the battery is dead then it wouldn't be chirping anyway.

Yes. Check to make sure hardwired power is there (circuit breaker or meter if you can) and install a fresh battery. If it still chirps replace it. This is the same reason I replaced all of mine. (They were all about the same age)

No batteries needed, not rechargeable, comes with AC cord. Plug into any outlet. I'm unsure of pixels, haven't used it in a while. I only needed it for a short time. Hope this helps.

It comes with it's own power supply and plug. This item does not use batteries.

The battery will only last an hour or 2 when not plugged in. They state that in the owners manual and I have tested it myself. I will tell you though the monitor is amazing and I love it!! It is super easy to set up, has good night vision and great sound. I am very happy with it!

It is analog and no batteries. I presume it is accurate. Not sure if it is ok for commercial applications.

It does have a plug, no battery. Not sure what the voltage is though, sorry!
