Hello,
My DVDR will no longer retain the date/time when I store them in the memory and turn the machine off.. I have had the DVDR for a few years now and the problem has only started recently.
I believe it may be the internal battery but am unable to locate it inside the player. There is no problem once I leave the DVDR powered on.
If somebody can tell me where the internal battery is, it would help a lot!
Cheers,
David

Sounds like main system control memory IC fault. Either the IC or its retaining supply voltage might be in trouble. Contact any service technician. http://electronicshelponline.blogspot.com/
The camera's internal date/time "backup" battery is supposed to maintain the date/time for about 3 weeks with the camera turned off. If the camera is not used for a longer period, the date/time will need to be reset. If you are having to reset sooner than that, it is likely that the internal battery (not user replacable on most models) has failed.
If you remove and replace your batteries...you will not lose the memory. The unit will store up to 90 measurements in non-volatile memory...so it will stay there.
I have the same unit and use these directions....and never had issues with setting the date and time.
2.2
Setting the Date and Time
Your blood pressure monitor automatically stores up to 90
measurements values with the date and time. To make use of the
memory and average values functions:
• Set the unit to the correct date and time before taking a measurement
for the first time.
• If the batteries have been removed for more than 30 seconds, the
Date/Time setting will need to be set.
1. Press and hold the Date/time
setting button (
) to adjust the
date and time. The year digits
(2008) will flash on the display.
2. Press the Memory button ( ) to
advance the digits one at a time.
Notes:
• The range for the year setting is
2008 to 2030. If the year
reaches 2030, it will return to
2008.
• If you hold down the Memory
button ( ), the digits will
advance rapidly.
3.
Press the Date/time setting
button (
) to confirm the setting
when the desired number
appears on the display.
The year is set and the month
digits flash on the display.
4.
Repeat steps 2 and 3 to set the
month.
The month is set and the day
digits flash on the display.
5.
Repeat steps 2 and 3 to set the
day.
The day is set and the hour digits
flash on the display.
6.
Repeat steps 2 and 3 to set the
hour.
The hour is set and the minutes
digits flash on the display.
7.
Repeat steps 2 and 3 to set the
minutes.
The minutes settings is set.
Press the Date/time setting
button (
) to turn the monitor
off.
When adjusting the date and
time, press the Date/time setting
button (
) to turn the monitor
on, follow the steps above, and press the START/STOP
button to turn the monitor off.
It sounds like the CMOS battery(s) are dead. They hold the most recent boot information including current date. Assuming both machines are on the older side, it's entirely possible the CMOS batteries no longer are providing enough power to retain this information.

hold down the pointy black switch actuator while turning the machine back on, hold until machine beeps, close doc feeder

For the LexMark Wheelwriter 1000 you can only "Reprint" the information you have typed. Once you turn off the machine the "reprint" mode will not longer retain information.
The date/time battery is "built in" (not replaceable) to this model according to page 13 in the manual (available here). It is supposed to recharge when you have the regular battery installed, but if you leave the regular battery out for more than "approximately three weeks", the internal battery may go flat.
I'm not sure this has anything to do with the memory card issue, though. Check the battery problem by inserting a freshly charged battery, turning on the camera and setting the correct date and time, then turning off the camera and waiting an hour or so (with the main battery still in the camera). Turn the camera back on, and if the date and time have to be reset again, your internal battery may be bad, and the camera would need to be serviced.
The date time problem ist he internal battery[ A watch type button inside the camera body] has worn out- replacing it will be a workshop job. The other problem seems like wear and tear on the switch any repair will be costly. Just live with[out]it- or buy a new camera
