Installing ESI’s Cordless Handsets

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 is line-powered and therefore needs no AC power.

• 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 digital port on a 482 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 EMI

— 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.

A Digital Cordless Handset base station requires only a line cord to the phone system; AC power isn’t

needed because the base station receives power from the phone system via the line cord.

Once the base stations are installed and the Cordless Handsets charged, change each Handset’s channel by

pressing its CH key. Each Handset should have its own channel. There are 30 available channels on the

small Cordless Handset and 10 on the large Cordless Handset.

Note: Feedback may result if the Cordless Handset is within three inches of an ESI desktop Feature Phone.

RFI is radio frequency interference. EMI is electromagnetic interference.
