Pentax ES II ES II Manual - Page 24

FLASH SYNCHRONIZATION The Pentax ES II has FP and X terminals at the front of the camera body, and an additional X contact in the hot shoe atop the pentaprism housing. As indicated in the table, set the shutter dial at 1/60 X for electronic flash, with the flash cord plugged into the X terminal. Set the shutter dial at 1/60 or faster for FP class flash bulbs, with the cord plugged into the FP terminal. SHUTTER SPEED FLASH TIRM , NAL FP 1/1/ 000 1/ • • /250 • /125 • 1/ 6 0X • Electronic Flash • Use the hot shoe flash contact when using a shoe-mount electronic flash like a Honeywell Auto Strobonar with a flash contact on the foot. In this case, there is no need to plug the flash cord into the X terminal on the body front. The hot shoe flash contact turns to "hot" (switched on) only when you insert a shoe-mount electronic flash. It remains "cold" (disconnected) even when using an electronic flash with its cord plugged into the X terminal on the body front. This eliminates the danger of electric shocks. FF 22
