Canon 188A - Manual (Page 2)

Introduction
The Canon Speedlite 188A is an automatic,
electronic, flash unit for hot-shoe attach­
ment on the Canon A-series SLR cameras
such as AE-1 PROGRAM or A-1, and F-1
The speedlite mounts onto the accessory
shoe of the cameras for hot-shoe attach­
ment
On the A-1, AE-1 PROGRAM, and AE-1,
the 188A will set both the shutter speed
the aperture for the cameras set normally
for automatic exposure For the F-1, the
188A will set only the shutter speed or lens
aperture as well depending on the exposure
mode the camera is set for. For the AL-1,
AV-1 and AT-1, the flash will set the shut­
ter speed automatically while the aperture is
set manually
When the 188A is used with the AE-1
PROGRAM, a blitz mark lights up in
the viewfinder when the flash is charged.
After the shutter is released, the same dis­
play flashes on and off to indicate there
was sufficient illumination for the shooting
