Installation & warranty
A large panel weighs 40–60 kg, so mounting is not a job for a drill and good intentions. Our engineers check the wall type, set the mount height for the room, run and conceal the cabling, commission the Android and network settings, and hand over only after your staff have used it.
Warranty is handled on-site by our own service team — you call us, we come to the room. Spares for the brands we distribute are held in Pakistan, so a panel is not out of service waiting on an import.
