I've had the MRC AC Sounder in my Williams E7 for some time now and seems to work great.
Problem is, I haven't run it in probably 5-6 months.
It's been sitting on a shelf the whole time, with the battery still installed.
Should I remove the battery or let it sit inside?

If you're going to leave something for an extended period with primary batteries in them, it's always a good idea to remove the battery. I normally keep the removed batteries with the unit in a plastic bag so next time I go to use it, I have the batteries.
The MRC AC sounders that I use have no batteries. Thats why they are called AC. Batteries supply DC.
Dennis,
Good thought! I have the MRC AC Sounder and the ERR Cruise Commander installed, so maybe I got the 2 confused. Time to take a look!
Will report back soon.
Here ya go:
It's the round black thing with the finger tab on top (look under the red and black wires and the red antenna wire), it came with the kit. I would guess it's to keep the settings applied when the engine is off(?)
No battery cited in the 2 page pamphlet/owners manual. Are you sure that "47F" is abattery?
I'm not sure of anything at this point, but I thought I recalled having to put that thing in when I got the kit. Right now I'm not sure where the instructions are so I need to look for them.
You can download the manual (such as it is) from the MRC website.
It's a cap. No battery in these. I've installed a number of these units. That reminds me, I have to check with Frank at MRC to see if the new version is available yet.
