PRODUCT MANUAL v. 1/2020 WHAT’S INCLUDED: (1) LINK Flash Unit (1) AC Power Cord (1) Gel Diffusion Dome (1) 14mm Flash Tube (1) Shipping Cover ADDITIONAL ITEMS AVAILABLE: LINK Battery | LINK Battery Charger | HUB Remote | Color Gel Diffusion Domes Paul C. Buff Flash Units are designed for professional photography use. As with all electronic equipment, users must observe all warnings and safety precautions. Carefully read all operating instructions and safety instructions before use. WARNING! HIGH VOLTAGE! Flash units contain internal components that can store dangerously high voltages, even when the units are unplugged. Batteries should not be exposed to excessive heat (i.e. direct sunlight, open flame, etc.) GENERAL PRECAUTIONS Do not operate a flash unit on or around flammable materials. Keep the unit away from fire, flames, and heated surfaces. Do not insert any foreign objects into any ventilation holes. Do not carry or store a flash unit together with necklaces, hair pins, nails, paper clips, or any other small metal objects. Do not cover the unit during operation. Air circulation must be permitted. Do not obstruct ventilation holes by covering the unit while in use or by operating from inside a carrying bag. Do not operate or store a flash unit in or around water. High voltage equipment can cause electric shock when operated in or near water. Your flash unit should only be used in dry, moderate conditions where the equipment is protected from rain, dirt, sand and dust. Do not use ungrounded power cords, power outlets or power strips. Paul C. Buff, Inc. Flash Units may only be connected to 3-wire grounded AC outlets to avoid shock hazard. Do not connect the unit to an ungrounded outlet or to a two-wire extension cord or adapter that eliminates the ground prong. Do not use any cords that have been damaged. Paul C. Buff, Inc. flash units contain no user-serviceable parts. Never open, disassemble, or attempt to repair any components. Only qualified technicians should service the system as incorrect disassembly can create an electric shock hazard. Fingers and other foreign objects must never be inserted or dropped inside any of the vents. If the unit has been dropped or damaged, discontinue use and contact customer service. Do not attempt to make any changes or modifications as any modifications made, outside of those performed or approved by Paul C. Buff, Inc., may present hazardous conditions and void the warranty. The only user-replaceable components are the flashtube, cover, and stand mount. NOTE - RADIO FREQUENCY ENERGY The LINK 800WS Flash Unit features a built-in CyberSync transceiver. This unit makes use of the radio spectrum and emits radio frequency energy. Interference can be a factor, as the frequency used is shared with other users and electronics. Please adhere to local regulations when using this device. 3 GENERAL SAFETY INFORMATIONTABLE of CONTENTS GETTING STARTED 4 STAND MOUNT 4 PLACING ON A LIGHT STAND 4 SHIPPING COVER 4 ATTACHING MODIFIERS 5 POWERING YOUR UNIT 5 BACK PANEL DISPLAY 6 POWERING THE UNIT ON/OFF 6 DEFAULT SETTINGS 6 NAVIGATING THE BACK PANEL 7 FLASH MODES 7 MODEL MODES 7 MODELING LIGHT FOR VIDEO USE 8 SYNC MODES 8 FREQUENCY / CHANNEL 8 RECYCLE / READY INDICATOR 8 BATTERY INDICATOR 8 LINK BATTERY 9 CHARGING THE BATTERY 9 HUB REMOTE 10 ATTACHING THE HUB TO YOUR CAMERA 10 POWERING THE HUB ON / OFF 10 REAR DISPLAY 10 BLUETOOTH 10 SETTING THE FREQUENCY 11 SENDING A TEST FIRE 11 TTL MODE 11 HSS MODE 11 CHANGING THE DISPLAY BRIGHTNESS 11 CHARGING THE HUB 11 GENERAL INFORMATION 12 FAQ’S 13 WARRANTY INFORMATION 14 2 paulcbuff.com | [email protected] | 1.800.443.5542 GETTING STARTED The unit arrives with the stand mount tucked under the unit.

Tighten the large knob, by turning clockwise, while holding the locking handle with your flash unit at your desired angle. Once satisfied with its placement, push the locking handle in towards the stud mount to secure.To readjust the tilt, simply pull the handle outwards from the stand mount, reposition your flash unit, and then push the locking handle in towards the stud mount to secure the placement. Make sure that the unit is secure prior to releasing. STAND MOUNT The stand mount is made of aluminum and features a locking handle, and two knobs. The smaller knob is what attaches the stand mount to the stud of your light stand. The larger knob connects directly to the locking handle and allows you to control and secure the tilt position of the flash unit. SMALL KNOB LARGE KNOB LOCKING HANDLE The shipping cover is made of aluminum and provides protection to the flash tube when transporting or storing your flash unit. You MUST remove the shipping cover prior to turning on the flash unit. REMOVE THE SHIPPING COVER To remove the shipping cover, slide either of the quick-release levers to retract the four faceplate fingers holding the cover. QUICK-RELEASE LEVER SHIPPING COVER QUICK-RELEASE LEVER and HOLDING FINGERS The LINK faceplate utilizes a Balcar mount that has four holding fingers, controlled by the quick-release levers.
