Connecting your
ESI Cordless Handset

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 thus needs no AC power.
• Wall-mount(s), a belt clip, and a Quick Reference Guide.

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 (radio frequency interference) or EMI (electromagnetic interference) — e.g., a television, radio, computer, computer printer, flourescent 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.

An IP Cordless Handset base station receives PoE. If PoE isn’t already being supplied, you’ll need to install the separately purchased PoE adapter (sold in five-packs as ESI part # 5000-0437).

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.
