About this manual

This manual begins with important safety safeguards for using the flash, including proper handling of cords, battery replacement, and avoiding water exposure. It then describes the flash unit’s components, such as the open‑flash button, sensor socket, zoom/bounce head, and various dials.

The guide explains the multiple power sources (four AA alkaline batteries, Ni‑Cad packs, HVP‑7 high‑voltage pack, PPG‑1 pistol‑grip pack, and SB‑4 AC adapter), the battery‑saving circuit, capacitor forming procedure, and how to attach the flash to a camera. Detailed sections cover automatic and manual operation, the Ready Light indicators, zoom positions, mode selector settings, and shooting techniques for on‑camera direct and bounce flash.
