To achieve optimum operation from your ESI Cordless Handset II Repeater: • Place the Repeater at least six feet off the ground so it has a clear line-of-sight. • Make sure the Repeater has good reception from the base station (or Repeater to which it is daisy-chained). • Make sure the Repeater location is close to a standard 120 VAC power outlet. • Never install electrical cords across traffic areas where they can cause a tripping hazard (additionally, such cords, if damaged, may create fire or electrical hazards). • Allow at least 35 feet between Repeaters. If you install Repeaters across multiple floors, be sure to allow 35 feet vertically, too. • Install the Repeater away from sources of electrical interference. Examples include audio systems, office equipment, and microwave ovens. • Install the Repeater away from heat sources and direct sunlight. • Install the Repeater away from items that can interfere with radio signals. Examples include metal doors, thick walls, niches, and cupboards.
