Question about Casio Cassiopeia E-125 Pocket PC

1 Answer

Lost data? My Cassiopeia E-125 doesn't turn on. The amber light just blinks once as I connect the power transformer directly to the PDA. I left it unplugged / uncharged for about a week. It won't take a charge now. I understand it probably will work with a new battery. anyway to save/retieve data?

Re: Lost data?

Leave the backup battery in the PDA and bring it back to life with this how to ;)

if that doesn't help you may need to give the battery a little kick-charge for the PDA to recognize it again. the PDA "thinks" there's not battery if the battery voltage is below 2Volt.
to "kick-charge" the battery just get a AC adaptor with at least 5V and 1A (a.k.a. 1000mA) with 2 wires and connect them to the battery pins (with "+" and "-" correct!)

if you have your PDA lying in front of you with the display down and the battery cover opened, the pins of the battery are as following:

left: plus
middle: charging/temperature (not important for hand-charging)
right: minus

connect the wires of the AC adaptor correctly and let it "kick-charge" for about 5minutes (but NEVER let it charge any longer if the battery is getting hot!!!!)

after that, the PDA should recognize the battery again because the voltage is more than 3Volt again.

but don't (!) try to power it up after kick-charging!
the batterys voltage is higher than 3Volt again, but it takes just a few seconds to empty it again if u try that.
it's only for the PDA to "see" the battery again ;)

Cassiopeia E-125

I had the same problem with an E125 which I brought off eBay that hadn't been used for several months.
I took out the backup battery and put the main battery in it's holder with a bare wire held onto the negative & positive terminals.
When I turned on the charger, I held the other end of the bare wires onto a partly charged Nokia Battery (Also 3.7V internal). The current from this battery was enough to let the Casio start charging.
After two minutes I disconnected the Nokia battery and gently tugged the bared wires free. The Casio kept on charging happily.
After six hours I disconnected the AC charger, installed a new backup battery CR2032, and everything was go.

My Cassiopeia came with a 4 digit pass code on it from another user how do i get that off of the computer so i can use it

Casio claims that once a password has been set in your unit it can't be reset without losing all data. You can try resetting and see if that works. Use ur stylus and press the reset button for about 3 seconds.

When charger is plugged, amber light blinks once and then nothing? E125 not working at all!

The Casio PDAs will quit charging very quickly if the battery is very, very discharged. If you continue to remove and re-insert the charger into the PDA's power socket, the recharging cycle will last longer and longer until finally the stupid thing will fully recharge its battery.

I have two Casio PDA's and three batteries that were recovered after a bit of tedious struggle to force the charging cycle to complete.

Casio e-125 problem

Sounds like you might have a bad cable or something. Did you try plugging ppc into its power pack while using the cable?

My E-125 isn't working properly...

If your craddle has DC power input that charges the PDA while in craddle, try setting the power configuration so that when the PDA is on external power, there is no blank screen timeout, and no automatic shutdown (it's in the Settings menu). This way, it won't power down while in craddle, and you won't get this problem you're having.

Microsoft Outlook data won't synch

In ActiveSybch there is an option of setting the priority of either the PC, the PDA or leaving the items unresolved. You can either change this of follow another route. With the device off the cradle delete the partnership WITHOUT deleting the partnership folder. Place the device on the cradle & let AS find the device & setup the partnership. Once setup remove the device & go to options & set all the required options. Replace the device & it should synchronise. If you still have problems please contact me directly through email.

Casio E-125

Blinking amber light means the battery is not fully recharged. Once it is charged, press the power button. If the the device still does not turn on take out the main battery and the backup battery. Put the main battery in first, then the backup battery and put the battery switch in the lock position. Press the power button and you should see initializing memory..., then starting..., then it will ask you to set up the device.

E-125 connecting to Siemens ME 45

There are 2 things you could try. If you have a serial data cable for both the devices try using a nul modem (Casio part # SB-91 includes best nul modem ever made ) & select Hayes compatible on serial port on E-125. If you have a built in modem in ME-45 it should work. Similarly you could use MS Outlook as an intermediary for transferring your E-125 telephone numbers to ME-45.
