ESI Cordless Handset II connection
Each ESI Cordless Handset II 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 II.
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 or EMI
fluorescent light fixture, or fax machine.
•
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.
Note: Your facility may be equipped with one or more optional Cordless Handset II Repeaters. For more
information about this, consult your System Administrator or your Certified ESI Reseller.
A Digital Cordless Handset II 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 II 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).
Notes: If the PoE equipment plugs into AC outlets and a power failure occurs, all IP Cordless Handsets II on the
system will be unable to originate or receive phone calls. Therefore, either: (a.) use an appropriately
sized uninterruptible power supply (UPS) to power all the IP equipment (base station, PoE adapter,
router, etc.) involved in making phone calls or (b.) have a traditional phone available for originating and
receiving analog CO calls.
Feedback may result if the Cordless Handset is within three inches of an ESI desktop phone.

RFI is radio frequency interference. EMI is electromagnetic interference.
