Digital delivery timing confirmed separately
$ 1,995.00
The SiNGRAY G2 Developer Support License is an optional one-year developer enablement and engineering-support program from HMS for developers, ISVs, system integrators and enterprise innovation teams building or validating G2 applications.
Included support
- SiNGRAY SDK and API integration guidance; OpenXR integration support; Unity/MRTK development assistance subject to the supported toolkit version.
- Architecture review, development-strategy consultation, recommended practices and performance-optimization guidance.
- Investigation of SDK integration issues, runtime errors and device/API behavior; issue reproduction and technical analysis.
- Access to SDK packages, API documentation, sample projects, firmware/software release notes and technical updates.

Custom application development, customer application debugging, source-code modification, customer-specific implementation, on-site engineering, hardware modification, product customization and third-party software debugging/support are excluded.
How it differs from standard support
Standard product support handles usage issues, operational problems, defects and RMA. This separate optional program supports application development and integration. It is not a third-party software license, a custom-development contract or a headset warranty extension.
Engagement and delivery
One-year remote program. Commencement, scheduling and project scope are confirmed with HMS. No physical item is shipped. Headset hardware, third-party applications and implementation work are separate.
FAQ
Is this a software application license?
No. It is a one-year technical-support program for development on SiNGRAY G2. It does not provide a third-party business application or include headset hardware.
How much consultation is included?
Up to four hours per month of remote engineering consultation. Scheduling and service commencement are confirmed by HMS; no carry-over allowance or guaranteed response time is stated.

Frequently asked questions
Is G2 optical see-through or camera passthrough?
Optical see-through. The wearer views the workplace directly through the optics, with digital content overlaid. Electrochromic glass adjusts transparency.
Which software is included?
The operating system and HMS system software are included. Authorized administrators can use SiNGRAY G2 Configure. Third-party applications, subscriptions and optional developer support are specified separately.
Can an existing HoloLens or OpenXR app run directly?
Applications are reviewed, migrated and tested rather than assumed to install directly. Confirm the engine version, OpenXR extensions, input model and dependent services.
Can the battery be changed while the headset is running?
Yes. The replaceable 2500 mAh / 7.6 V (19 Wh) battery is hot-swappable. Follow the user-manual procedure; backup power keeps the device running during a compliant swap.
Does G2 work offline?
Compatible applications can run on-device. Remote assistance, cloud content and other online functions still require a network connection.
What about PPE and prescription glasses?
G2 accommodates prescription glasses. Fit with the specific PPE required at a site must be evaluated; this is not a blanket safety-equipment certification.
How are delivery and certification confirmed?
SiNGRAY G2 is available to order through Knoxlabs. HMS confirms that SiNGRAY G2 mass-production units are undergoing FCC and CE conformity assessment. Documentation is pending. Confirm the applicable model, destination-market requirements and dispatch timing with Knoxlabs before ordering. Delivery timing is confirmed for each order.
What warranty applies to mass-production headsets?
HMS's August 2026 RMA policy describes a 12-month limited warranty from the HMS ship date. An evidenced later start may be adjusted by up to 90 days. The supplied Limited Warranty and applicable law govern; contact Knoxlabs before returning a unit.
