Overview
The same concept as the 8400 range, more affordable
The Savi 7400 Office rests on the same principle as the 8400 range. The desk base links a computer, a desk phone and a mobile, and the user switches between three sources of calls on one headset. Range and battery life are the same; what differs is the headset's own equipment. Where the customer does not need the top tier, the 7400 is the more sensible choice.
Acoustic Fence against voices from the next desk
This range has a noise-cancelling boom microphone with Acoustic Fence technology. It is aimed at keeping colleagues' conversations at neighbouring desks out of what the far end hears. In an open plan office and in a contact centre that is more useful than cancelling steady background noise, because it is other people's voices that distract most.
The range can be reduced, and sometimes it needs to be
Range is adjustable across three levels. On the default high setting the user guide states up to 300 feet, on medium 150 and on low 50. In a dense deployment, with many bases on one floor, reducing the range limits mutual interference. It is one of the things that gets forgotten when designing a larger rollout.
Strengths and limits
Strengths
Computer, desk phone and mobile on one headset
Acoustic Fence against voices from neighbouring desks
Adjustable range, useful in a dense deployment
The base, cradle and telephone cable are in the box
Limits and what to tell the customer
Do not count on active noise cancelling for playback on this range. The cancelling works on the microphone side. Anyone who needs to be cut off from the surroundings belongs with the 8400 range.
We do not carry a universal version of the 7410, only the Microsoft Teams version. We will confirm availability.
The headset is tied to its base. It is not a device to take home and pair with a laptop.
The DECT band is regional. For this market it is 1880 to 1900 MHz. Units from the US market work in a different band and cannot be operated here.
⚑ atlantis note
When 7400 and when 8400
Range, battery life, three-way connectivity and conferencing four headsets are the same on both ranges. The difference is in the headset's equipment: the 8400 has hybrid active noise cancelling, on the 7400 do not count on it. So ask about noise in the room. Where the point is that the far end hears cleanly, the 7400 with Acoustic Fence is enough.
The battery is planned maintenance, not a fault
The battery should be replaced after three years or 500 charge cycles, whichever comes first. On DECT headsets in a contact centre that means a planned replacement, not a warranty claim. It is worth raising up front and including spare batteries in the quote.
The handset lifter is ordered separately
The telephone interface cable is in the box, but the HL10 lifter and the EHS cable are not; the user guide lists them as sold separately. Without them, calls on the desk phone are answered by hand. We will pick the right type for the make of phone.
Who it suits
Recommended use | a wireless DECT system with three-way connectivity, that is to a computer, a desk phone and a mobile, with a microphone using Acoustic Fence technology |
|---|---|
Position in the portfolio | wireless DECT headsets for the office and contact centres; the 7400 range is the more affordable current range of the Office branch |
How it differs from the Savi 8400 range | range, battery life and three-way connectivity are the same; the 8400 adds hybrid active noise cancelling, the 7400 does not |
Good fit
Contact centres and open plan offices where voices from the next desk are the distraction. Workplaces with a desk phone next to the computer. Larger rollouts where cost per seat matters.
Check
Whether the user needs to be cut off from the surroundings, in which case the 8400 range applies. The make of desk phone, because of the lifter. Deployment density, because of the range setting. Whether it is the European DECT band.
Consider another model
Savi 8400 Office for active noise cancelling, Savi UC for a computer-only connection, EncorePro for a wired contact centre deployment, Voyager for hybrid work.
The "Check" and "Consider another model" cards come from the experience of the atlantis team.

What to check before ordering and deploying
Noise in the room: if the user needs to be cut off, the 8400 range applies, not the 7400
Make of desk phone: it decides the type of lifter, electronic or mechanical
Deployment density: with many bases on one floor, lower the range setting
DECT band: the European version for this market; US units cannot be operated here
Batteries: planned replacement after three years or 500 cycles, include it in the quote
Management and training: registration in Poly Lens and switching the three call sources on the base
The atlantis team will help with every point. From picking the lifter by phone make through designing deployment density to bulk configuration in Poly Lens.

Frequently asked questions
How does the 7400 range differ from the 8400 range?
Range, battery life, three-way base connectivity and conferencing up to four headsets are the same on both. The 8400 adds hybrid active noise cancelling for playback, the 7400 does not. Decide by whether the user needs to be cut off from the surroundings.
What is Acoustic Fence?
A microphone technology used in this range. It is aimed at keeping colleagues' conversations at neighbouring desks out of what the far end hears. In an open plan office and a contact centre that is usually more useful than cancelling steady background noise.
Why can the range be reduced?
In a dense deployment, with many bases on one floor, reducing the range limits mutual interference. The guide gives three levels: high up to 300 ft, medium up to 150 and low up to 50.
How long does the battery last?
Up to 13 hours of talk time on a charge. The battery should be replaced after three years or 500 charge cycles, whichever comes first. In continuous operation, treat that as planned maintenance.
Is the monaural model available for a platform other than Teams?
We carry the 7410 Office only in the Microsoft Teams version. We do not have a universal version of the monaural form in the price list. The stereo 7420 Office comes in both platforms.
