With good batteries in place, does unit retain results in memory if unplugged from AC adapter?

Sorry I can not answer this as I have not used the AC adapter with this machine. I take my B/P and write it down. I haven't even used the memory on the machine to see if it works. Sorry Pat

Yes it does. the only problem I had was when I dropped it and the batteries fell out. Works just fine, I have not yet brought it to my doctors to 'calibrate it' against their equipment however I believe it's pretty accurate.

Sometimes, if a NiCd or NiMH rechargeable battery is repeatedly recharged after being only partially discharged, it may lose its maximum capacity. This is referred to as battery memory. It is as if the battery only "remembers" the smaller capacity. So the product description is stating that this product is not susceptible to this effect.

It seems to pickup where it left off when I plug it back in after being off for a day or so. I don't know if this will be true over a long period of time if it is unplugged from power or if you remove the usb stick or SD card while it is off.

The person I purchased this unit for, leaves it plugs in at all time. She unplug unit for several day while on vacation, and the battery died. So I suggest you leave unit plug in at all time to preserve the battery life.

I don't know if it remembers if you remove the disk, but as long as the disk is in it remembers where it was when it shuts off. This works even if the batteries die.

This device, the P4400, will reset all of its timed measurement values to zero if power is lost or the device is unplugged. The P4460 has "non volatile" memory, using a battery to provide the necessary voltage to power the (S)RAM memory, which means that it will not lose the data if power to the 4460 is lost. The P4460 also will let you input the cost per KWH from your provider to calculate the cost to operate the appliance over a week, month and year (assuming that your use is the same during the extrapolated period as it was during the measurement period). For me the data retention feature is well worth the extra $4 since I want to keep track of the energy used by a window air conditioner which will vary by the outdoor temperature, the sun hitting the building, the humidity, etc.

I disassembled an old unit that failed to charge after a year or so and removed the batteries. They would not charge with a "hobby" charger designed for electric RC cars and such. I then discovered that storing the unit in the charger when it is plugged in was overcharging the batteries. I have another unit about 4-5 years old that is still going strong. I charge the batteries overnight when they will no longer last a full brushing cycle. NiCad and NiMH batteries have a very limited life when charged to 100% capacity repeatedly.

I have owned this computer for about one year now and keep it plugged in MOST of the time. When I unplug it I do not notice any reduction in battery life.

Yes. If the DC adapter is plugged into the 110 wall circuit & the DC input of the radio ** and the power is ON, the (6 C) batteries are just ballast (it works without the batteries installed as well). Once the adapter is unplugged, power is switched to the batteries seamlessly (& vise versa). If the adapter is plugged in and the power switch is OFF and there are rechargeable NIMH C batteries in the radio and the battery switch is on NIMH, the batteries will be charged. If the batteries are alkaline, the battery switch must indicate Alkaline so the unit does not attempt to charge them. ** The DC input is 12V 700 mA... so any adapter (120V to 240V) that produces the required DC output should work fine.

Absolutely not. Unit operates when plugged . Once you unplug ,if turned on ,starts operating using the batteries.

Powered with a AC/DC adaptor and it appears it has a battery keeps the memory when the device is unplugged. Photos are transfered with an SD card, not USB.

It is possible to use this unit with power supplied from the AC outlet by turning on the unit with the AC adapter connected.Even when you use the AC adapter for recording images, keep the battery connected.This allows you to continue the recording even if a power failure occurs or the AC adapter is unplugged from the AC outlet by accident.

The settings are stored in non-volatile memory. In other words, long term memory like a flash drive. I've had it unplugged for several months and it retains the set points.

The unit is powered by using the AC power supply, and it can also be powered using 3 AA batteries, you should use both together, in a power outage it will switch to using the batteries. Also the frequencies are stored in EEPROM non volatile memory, which means that it will stay in memory even when there is no power.Thank you.

No leave the battery in the device. The circuitry detects if the device is receiving power and then charges the battery and runs the device at the same time. When the battery completes charging the unit continues to run on AC till you unplug from the wall socket. It is a nice feature that you can run it and charge the battery at the same time.

Usually its memory keeps record of state when it was switched off. So when you switch it off at HIGH mode, it will, or at least it should go ON at high mode next time.

Hello Kelly, From my experience it saves your settings. I think you can think of the memory in this more like a flash drive. when not powered it still keeps the info. it does not have a battery inside, but i dont think it needs one. it is also part of your alarm system and would be using the juice from its battery in case of a power outage. hope this helps
