The following is a letter from olympus (UK) dating 14--6-1988 after
repairing my OM4

"Dear customer , 
In line with continual improvements to olypus products your camera has been
fitted wiwth a replacement integrated circuit board which offers the
following aditional feautures.

1) battery check switches off after 30 secs
2) memory clear can now be operated whilst the viewfinder display is in the
off mode.
3) with the camera in the auto mode any non-om flashgun can be fired from
the hotshoe and X-synchro socket , for the use of fill in flash (speed must
be below 1/60)
4) with T system flash , viewfinder charge signal will now switch off after
120 secs. to reactivate lightly touch the shutter release
5) on long auto exposures , shutter can be overridden and made to close if
the selector dial is switched to either manual or battery check.

Please note that points 2 & 3 now override the relevane question and
answers sections on pages 35,39 and 50 of intruction book B."

right .. OM4 check time :)
