Interrupting the Exposure
If the exposure key is prematurely released, the expo-
sure is interrupted and terminated.
The kV/mA value and the LED over key R blink at the
Multitimer.
The exposure time passed until the interruption is

Automatic Exposure Blockage

The LED over key R continues flashing until the cool-off
time has elapsed.
The exposure cannot be triggered until the LED over key
R has gone out.
