Does this scanner have a battery backup? Older scanners don't and with a power outages erases stored frequencies after a few minutes.

it does have a battery back up. but you must install batteries and use the ac adapter for power source.

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.

Yes. The scanner has a frequency search so you if you either know it by heart or can find it somewhere you should be ok. I can refer you to a website where you may be able to find it if you want? :)

3 AA batteries. It comes with an AC power adapter/charger and it will work with the adapter/charger providing the power, thereby saving the batteries. However, it will not charge unless the scanner is turned off. It's best to use rechargeable batteries, and to buy an extra set and a separate battery charger. That way, when the batteries get low, you can swap them out and charge the ones that had been in the scanner.

after a power outage it looses memorized stations and the clock has t be reset

Regarding the questions about "battery" backup. I just spoke with P3 tech support. No, there is no battery; yes, there is a memory chip installed which stores recorded data. So no worries about leaking batteries...

scans to sd card battery did not work good two scans and went dead. good clear scan and not to slow, great for trips do not need a computer to scan something.

Yes, it does have a digital answerer you can turn off or on. I'm not sure what you mean by the second question, but I've never had to reenter my stored numbers in spite of power outages. Hope this helps!

I have owned this scanner for the past 4 - 5 month and have scannned at least 100 pages and have not yet had to replace the battery. Very satisfied

No it doesn't. You need a scanner that has a back-light. Epson and others make that kind of scanner.

Yes it does. You just need to be sure they are analog and not digital. This scanner will only receive analog broadcasts. You can find out by checking at radioreference.com in their database.

No. Powered off USB plug. Great scanner, If doing hi-res work make sure to run the calibration procedure before you start- worth the extra minute!

This is a terrible product and failed after about 2 uses. I recommend you buy another portable scanner. To answer your question: these type of scanners only scan one side at a time.

No it does not forget during a power outage .The memory only holds a couple of hundred phone numbers . After a year or two the call blockers phone number memory fills up and the phone starts ringing again..You can not add new phone pests any more.Like during the weeks before election time. Dag Nab it !Had to answer the phone 5 times today people wanting me to vote for them.I want a automatic dialer zapping machine that can smoke a automatic dialer with the push of a button.

This radio does not have battery backup. If you have the radio set to get the time from the internet and you have wifi signal (or you are using Ethernet) the radio will automatically keep the time. If you unplug the radio or the electricity goes off, the radio will have to reset the time, date and so on. The radio will reboot and do it's setup thing when the power comes back on.

If you mean the scanner, it is powered from your car battery when you plug it into the OBD port. If it is not turning on, it is not getting power from the port or it has failed. You can try it on another car to see which.

YES. I have unplugged the base unit several times as I put my new office desk in order. The backup power from the handset is limited by the rather small AAA batteries, so I don't expect it to last very long. In my experience, the majority of power outages or brown-outs are very brief (i.e. less than 2-3 seconds) and anything longer is probably going to be hours, not minutes. I think this is a thoughtful feature and it's showing up in more and more ordinary devices that aren't much fun to re-program. It works unless the handset isn't in place during the outage, but even then, I didn't lose any programming (addressbook, speed dialing, and cell phone pairing). YES.

The unit has a compartment for two button type batteries (supplied with the unit) that back up the memory if the power goes out. So the answer is: yes.
