Never operate dock equipment while a safety device or guard is removed or disconnected. Never remove DANGER, WARNING, or CAUTION signs, Placards or Decals on the equipment unless replacing them. General Operational Precautions Recognize Precautionary Information PRECAUTIONS Safety-Alert Symbol The Safety-Alert Symbol is a graphic representation intended to convey a safety message without the use of words. When you see this symbol, be alert to the possibility of death or serious injury. Follow the instructions in the safety message panel. The use of the word DANGER signifies the presence of an extreme hazard or unsafe practice which will most likely result in death or severe injury. The use of the word WARNING signifies the presence of a serious hazard or unsafe practice which could result in death or serious injury. The use of the word CAUTION signifies possible hazard or unsafe practice which could result in minor or moderate injury. The use of the word NOTICE indicates information considered important, but not hazard-related, to prevent machine or property damage. Indicates a type of safety sign, or separate panel on a safety sign, where safety-related instructions or procedures are described. 2 4111-0096 — June 2026 © 2026 Systems, LLC Only trained personnel should operate the dock leveler and vehicle restraint. DO NOT use a broken or damaged dock leveler or vehicle restraint. Make sure proper service and maintenance procedures have been performed on the equipment before operating. Transport vehicle wheels must be chocked unless the vehicle restraint is used. Never remove the wheel chocks until loading/unloading is finished and transport vehicle driver has been given permission to leave. Make sure platform lip rests on the transport vehicle bed with at least 4 in. (102 mm) of overlap. Maintain a safe distance from side edges of leveler during the loading/unloading process. FAILURE TO FOLLOW THESE INSTRUCTIONS WILL RESULT IN DEATH OR SERIOUS INJURY. The Link 2 is designed and intended to monitor loading dock availability for warehouse management systems. Do not rely solely on this device for safe loading dock operations. Always verify the transport vehicle is properly restrained via wheel chock or other restraining device/method. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DEATH OR SERIOUS INJURY. • Read and follow all instructions, warnings, and maintenance schedules in the manual and on placards. • Wheel chock restraint operation and servicing is restricted to authorized personnel. 1. Before using the vehicle restraint: • Remove any debris, snow, or ice that may obstruct the operation of the wheel chock to restrain the transport vehicle. • Alert personnel in the area of potential operation of the wheel chocking system. • Operate the wheel chocking system through one complete cycle, inspecting it for proper operation and light sequence. Advise maintenance personnel of any damage or improper operation immediately. Remove all malfunctioning or damaged wheel chocking systems from service using approved lockout/tagout procedures. 2. Before attempting to restrain a transport vehicle: • Verify that transport vehicle is positioned squarely against dock bumpers. • Inspect the transport vehicle’s wheel area. Fenders or shrouds near the wheel may obstruct and not allow the wheel chocking system to securely capture the transport vehicle wheel. 3. After activating vehicle restraint: • Verify that the wheel chock is fully engaged and centered with vehicle tire. • If equipped with a light communication system, load and unload on GREEN light only. 4. Maintenance or service must be performed by authorized personnel only. Follow approved lockout/tagout procedures. FAILURE TO FOLLOW THESE INSTRUCTIONS WILL RESULT IN DEATH OR OTHER SERIOUS INJURY. VEHICLE RESTRAINTS Only for UniChock™ ENGAGE WHEEL CHOCK 1. Place chock in front of wheel. (Inside AMBER light indicates chocking in process) 2. Alarm & GREEN inside light will indicate proper en…

Where the gain of the antenna is inherently accounted for as a result of the measurement, such as field strength measurements on a part 15.249 or 15.231 device, so the gain does not necessarily need to be verified. However, enough information regarding the construction of the antenna shall be provided. Such information maybe photographs, length of wire antenna etc. The antenna gain information shall be made public (not confidential). Any proprietary information such as construction maybe stripped from the gain information report and held confidential. The main antenna information we require is the maximum gain of the antenna for the band of operation.
