We are there for you
We are here for you - even years after you have purchased our products. For us, qualified service in all areas is just as important as comprehensive consulting by our sales team.
G&D regards these aspects as the basis for a working partnership.
Our support – personal and competent
As in many sports, some personal bests are only possible when working closely with a strong team. The G&D technical support team is such an essential player within the G&D service philosophy.
Our staff is only one phone call away to take charge of your request.
G&D support offers more…
- Consulting and planning of complex KVM installations
- Free of charge loan equipment - before purchasing and during repairs
- On-site installation and start-up of G&D devices
- Reliable troubleshooting
