[TenTec] Orion backup battery

[jack]

please tell me where the battery is in the Orion. I had "battery failure" on 
screen just now. all memories and frequencies have to be punched in now and 
then tuned. the 3rd edition of the manual does not have any "battery" 
notation at all. I have the Adobe Acrobat version searchable.

TEN-TEC Sold me the ST Microelectronics M4T28-BR12SH1 Timekeeper snaphat
lithium cell


for $5 + $3 shipping in January of this year. Note M4T, not Z.



It's [January 2011] data sheet:
http://www.st.com/stonline/books/pdf/docs/13125.pdf was unfound today on
internet.

The DIP Extractor tool pictured in above looked like simple, flat-sided
tweezer to pry it up, with small teeth at ends to prevent dropping device.

[ orion565 at yahoogroups.com comments said small screwdriver works]



Its Jan 2011 still available ST Microelectronics Application Note:


http://www.datasheetcatalog.org/datasheet/SGSThomsonMicroelectronics/mXyyqty.pdf

Use- Life appears to be 7-10 yrs. Storage-Life could be much longer

Mine failed Jan 2011 after approx 7 to 8 yrs near-daily use


I hope this as helpful to you as your inputs to the site have been to me.
