Hello!

I have got a Tek 2465B which displays this error on startup:

TEST 04 FAIL 11

PUSH A/B TTRIG TO EXIT

From the Service Manual, it seems a calibration data error. Does it
mean there is some faulty non-volatile RAM?. If so, is it replaceable
with a current type?. Any hint to fix this?

I have very recently repaired my 2465B and successfully replaced the lithium
battery with a pair of AA's in a battery holder stuck to the PCB with some
double-sided foam adhesive tape. I used decent AA's (Duracell Ultra) in an
attempt to reduce risk of leakage.

Recalibration takes quite some time afterwards, so be prepared!

Cheers, Howard
