Poly CS540A – Convertible DECT Headset TAA Compliant

Product Overview

The Poly CS540A TAA compliant DECT headset is a convertible wireless headset built for federal, state, and local government desk phone deployments where Trade Agreements Act sourcing is a contract requirement. Part number 7W073AA#ABA is the TAA variant of the CS540A operating in the 1920-1930 MHz North American DECT band, pairing a noise-canceling boom microphone with roaming range up to 400 ft from its office base. Three wearing styles ship in one box, so a contracting officer can standardize a single line item across an agency instead of stocking separate SKUs. It connects to an existing desk phone rather than a computer, making it a direct fit for secure workspaces where USB peripherals are restricted.

Product Description

Procurement teams buying under GSA schedules, SEWP, or agency-specific vehicles are usually constrained twice: once by the technical requirement and once by TAA country-of-origin rules that disqualify otherwise-suitable hardware. The CS540A TAA SKU exists to resolve the second constraint. It is listed by HP Poly as TAA compliant, and Creation Networks supplies it as the part number written into government solicitations. Verify the specific TAA determination and country of origin against current HP documentation for your solicitation before award, as sourcing can change across production runs. We do not publish a certificate number we cannot substantiate for a given lot.

Technically the headset is a mature, low-risk choice for desk-phone-centric offices. It is a monaural DECT headset with a convertible design offering over-the-ear, over-the-head, and behind-the-head wearing options, which removes the fitting problem that drives returns in large rollouts. The noise-canceling boom microphone reduces background noise from adjacent workstations, and SoundGuard acoustic limiting caps output below 118 dBA to protect against acoustic shock — a documented workplace safety consideration in call-handling roles. Users select narrowband audio to extend talk time or wideband audio for higher voice intelligibility, and enhanced digital signal processing keeps the far end natural rather than compressed. An adaptive power system steps the radio down when the headset sits near its base, which preserves battery and improves density in floors running many headsets side by side.

Deployment is simple for a facilities team. The office base connects to a desk phone through the included telephone interface cable, and remote call answer is added with an HL10 handset lifter or an electronic hook switch cable matched to the phone model. Up to four headsets can be conferenced onto a single base for training or supervisor monitoring. Agencies moving toward softphone workflows or requiring stereo wearing styles should compare the Poly Savi 7320 UC stereo DECT headset, which adds AES 256-bit encryption and a USB DECT adapter, or the Poly Savi 7410 Office monaural DECT headset for three-way computer, desk phone, and mobile connectivity. Where the desk phone itself is being refreshed alongside the headset, the Poly Edge E500 IP desk phone is a common TAA-conscious pairing.

Key Features

• TAA Compliant SKU — Part number 7W073AA#ABA is the Trade Agreements Act variant, supplied for federal and public sector contracts that require TAA-compliant sourcing.
• Convertible Three-Style Wearing — Over-the-ear, over-the-head, and behind-the-head options ship together, so one line item fits every user in an agency rollout.
• 400 ft Roaming Range — Staff can leave the desk and stay on the call anywhere within 400 ft of the office base, covering a typical floor plate.
• Noise-Canceling Boom Microphone — Background conversation from adjacent workstations is suppressed so the far end hears the speaker, not the office.
• SoundGuard Acoustic Protection — Output is limited below 118 dBA to guard against acoustic shock during sustained call-handling work.
• Wideband or Narrowband Audio — Users choose wideband for voice clarity or narrowband to extend talk time, with enhanced DSP on both paths.
• Adaptive Power System — The radio downshifts when the headset is near its base, preserving battery life and improving headset density on busy floors.
• Conference Up to Four Headsets — Four headsets can share a single base for supervisor monitoring, side-by-side training, and quality review.
• Remote Call Answer Ready — An HL10 handset lifter or electronic hook switch cable adds answer and hang-up from across the room on supported desk phones.
• Desk Phone Connectivity — The base connects over RJ-11 through the included telephone interface cable, suiting secure areas where USB peripherals are restricted.

Typical Applications

• Government space
• Commercial meeting space

Technical Specifications

Frequently Asked Questions

Is this the TAA compliant version of the CS540A?
Yes. Part number 7W073AA#ABA is the TAA variant listed by HP Poly as TAA compliant, and it is the SKU government buyers should reference on a solicitation or purchase order. For a specific award, confirm the current country of origin and TAA determination against HP documentation for the production lot you are receiving, since sourcing can change over time.

Can this headset be purchased through GSA and other government vehicles?
Government buyers routinely procure this part number under GSA schedules and agency contract vehicles. Contact Creation Networks with your contract vehicle, agency, and quantity, and we will confirm current availability, lead time, and pricing for the TAA SKU rather than the standard commercial variant.

What does it connect to — a computer or a desk phone?
The CS540A connects to a desk phone. The included office base attaches over RJ-11 using the supplied telephone interface cable. There is no USB adapter in the box, which makes it a practical choice for secure workspaces where USB peripherals on the endpoint are restricted or prohibited.

How do users answer calls away from the desk?
Add an HL10 handset lifter or an electronic hook switch cable matched to the desk phone model, both sold separately. That combination lets a user answer and end calls from anywhere within the 400 ft roaming range without returning to the phone.

Which wearing style should we specify for a large rollout?
None — that is the point of the convertible design. Over-the-ear, over-the-head, and behind-the-head components ship in every box, so users self-fit at deployment. This removes the per-user style survey that typically delays large agency rollouts and reduces exchange requests after issue.

How many headsets can share one base for training?
Up to four headsets can be conferenced onto a single base, which supports side-by-side training, supervisor monitoring, and quality review without a separate recording or bridging appliance.

Does it protect users against acoustic shock?
Yes. SoundGuard acoustic limiting caps output below 118 dBA, which addresses the sudden audio spike risk in sustained call-handling roles and is commonly cited in workplace hearing safety requirements for contact center and dispatch positions.

What warranty and support are included?
The headset carries the Poly standard one-year limited warranty. Poly+ service agreements are available separately for extended coverage and advance hardware replacement. Contact Creation Networks for quotes on multi-unit government orders, TAA documentation requests, or help matching EHS cables to your installed desk phone fleet.
