MERCURY LUX PC V3.0
END-USER LICENSE AGREEMENT

Copyright (c) 2026 KM3KM Electronics LLC. All rights reserved.
Revision date: October 29, 2026
Contact: km3kmcontact@gmail.com

This agreement describes the license for Mercury LUX PC software and the
conditions for using its optional remote-access service. "You" means the
person or organization using it.

1. LICENSE TO USE

KM3KM Electronics LLC grants you a limited, non-exclusive, non-transferable
license to install and use the official software on compatible Windows
computers you own or control, with Mercury LUX equipment you are authorized
to operate. You may install it on both a station computer and a
remote-control computer.

The software is licensed, not sold. This license does not transfer ownership
of the software, documentation, branding or other intellectual property of
KM3KM Electronics LLC.

2. LOCAL USB OPERATION

Local USB operation is available without a Mercury account or remote-access
subscription. Compatible equipment, a suitable USB connection and supported
Windows software are required.

3. OPTIONAL REMOTE ACCESS AND BILLING

Remote sharing and remote control require an account with valid access time.
Access may come from a confirmed payment or time expressly granted by KM3KM
Electronics LLC. Creating an account alone does not activate remote access.

The standard remote-access subscription is USD 10 per month and renews
automatically until cancelled. The checkout displays the amount, first
charge date and recurring-payment terms before you authorize payment. Merely
accepting this software license does not authorize recurring charges.

Free access granted by KM3KM Electronics LLC is not, by itself,
authorization to charge you. When authorized access expires, remote sharing
and control become unavailable; local USB operation remains available.

4. CANCELLATION AND REFUND REQUESTS

To stop automatic renewal, open Remote Access > Manage Subscription > Cancel
Subscription and complete the cancellation. You may also cancel the
corresponding automatic payment through PayPal. Contact KM3KM Electronics
LLC if you need help.

Cancellation stops future recurring charges for the cancelled subscription.
Already-paid access remains available until its expiration date.
Cancellation does not automatically refund previous payments. Contact KM3KM
Electronics LLC to request a refund or report an incorrect charge; any
rights provided by applicable law or payment-provider dispute procedures
remain unaffected.

Logging out, closing or uninstalling the software does not cancel a
subscription.

5. ACCOUNT AND EQUIPMENT RESPONSIBILITY

Keep your password private and maintain an accessible recovery email. Use
only accounts and equipment you are authorized to access. Do not attempt to
access another customer's station or bypass access-time or payment checks.

Remote operation requires a working Internet connection and a station
computer running Mercury LUX PC with the amplifier connected by USB. Power,
network or service interruptions may prevent monitoring or control.

The software does not replace the amplifier's hardware protections or its
operating manual. Operate the equipment within its ratings and applicable
radio operating requirements. Do not rely on an Internet connection or an
on-screen reading as your sole means of equipment protection.

6. RESTRICTIONS

Without written permission from KM3KM Electronics LLC, you may not sell,
sublicense, commercially redistribute or distribute modified copies of the
software; remove ownership notices; or modify, decompile, disassemble or
reverse engineer it, except to the extent such restrictions are prohibited
by applicable law.

You may retain a backup of the official installer for your own use. Rights
provided under applicable third-party or open-source licenses are not
limited by this agreement. Those components remain subject to their own
licenses.

7. UPDATES AND SERVICE AVAILABILITY

Features and compatibility may change in later releases. This license does
not promise future features, permanent compatibility, uninterrupted remote
service or lifetime remote access. Paid services remain subject to the terms
accepted at purchase and any mandatory customer rights.

8. WARRANTY AND LIABILITY

To the extent permitted by applicable law, the software is supplied "as is"
and the remote service "as available," without a promise of error-free or
uninterrupted operation. Except for express commitments made by KM3KM
Electronics LLC and rights that cannot lawfully be excluded, KM3KM
Electronics LLC disclaims implied warranties of merchantability and fitness
for a particular purpose.

To the extent permitted by applicable law, KM3KM Electronics LLC is not
liable for indirect, incidental, special or consequential losses arising
from use of the software or remote service. Nothing in this agreement
excludes liability or remedies that applicable law does not allow to be
excluded, or changes a separate written warranty provided for the amplifier
hardware.

9. END OF LICENSE

You may end this license by stopping use of the software and removing your
copies. Cancel any remote subscription separately as described above.

KM3KM Electronics LLC may terminate this license or restrict remote access
for a material breach of these terms, subject to applicable law and any
required notice or opportunity to correct the breach. Mandatory customer
rights are preserved.

10. CUSTOMER RIGHTS AND CONTACT

This agreement does not limit non-waivable consumer rights or override
applicable law. If a provision is unenforceable, the remaining provisions
continue to apply to the extent permitted by law.

This license is not a substitute for a privacy notice concerning the account
and remote-access service.
