Installing ESI’s Cordless Handsets Note: Except where noted, this section applies to both the ESI Cordless Handset II and original ESI Cordless Handset models. Each ESI Cordless Handset comes with: • A charger/cradle to charge the Handset. • An AC adapter for use with only the charger. • A base station to provide a digital interface between the ESI phone system and ESI Cordless Handset. This base station needs no AC power: if the Cordless Handset is digital, the base station is line-powered; if the Cordless Handset is IP, the base station uses Power over Ethernet (PoE). • Wall-mount(s), a belt clip, and a Quick Reference Guide. Each ESI Cordless Handset is keyed to only one base station and takes up one port (digital or IP) on a port card. Base station installation Due to each site’s unique characteristics, the range and distance information we’ll provide herein is only approximate. Characteristics that positively affect performance: • The base station should be installed so it has a clear line-of-sight with the Cordless Handset. • The base station antenna should always be pointed in its uppermost vertical position. Characteristics that negatively affect performance: • Large amounts of metal shelving (such as in manufacturing or warehouse areas). • Close proximity to (within one mile of) a radio tower. • Concrete walls that divide spaces where Cordless Handsets are used (assuming the base stations are in one location). Don’t install the base station: • Close to a wall with metal studs. • On a metal wall. • Next to a device that emits RFI or EMI1 — e.g., a television, radio, computer, computer printer, fluorescent light fixture, or fax machine. • Next to any other 900 MHz device — e.g., a hand-held inventory control device. • In a ceiling that has foil-backed insulation. • Behind doors that typically are closed, tinted windows, one-way glass, or other areas that limit or cut off transmission to the Cordless Handset. Base stations must be installed at least 10 feet apart, regardless of whether the base station is for the small-model or large-model Cordless Handset. Don’t install more than six base stations in one area (such as a network room). Choose a location at least 30 feet away if more than six base stations are needed in a building.
