Hello all: Just opened a 2467 OPT 06, 10. SN B010xxx.
Works fine, call seems OK. ~3K HRs 150 cyc, Orig A1 U800, A5 thru hole
I plan to recalibrate but for the moment would attempt to just swap out the battery.
1/ Battery: Eagle Picher LTC-7PN 3.5V 750mah Keeper date code 2486.
Any Recommended replacement, see made in Korea and China and some seem to be knockoffs in plastic or metal cases.
Any recommended desoldering precautions?
How to replace battery without data loss?
2/ Cleaning: Have 2 that were never serviced, accumulated dust and dirt, especially near CRT and vent holes.
Use air (vacuum cleaner, compressed air or freon air can) to blow out?
cotton/Q tips and IPA?
Very wary of static or physical damage.
Many thanks!
Jon
