Service / repairing requirements
For you to give fastest possible response to the end users, we recommend:
You buy and keep a learning device in your warehouse. So you technicians can learn the
operation and repairing.
Your technicians collect and keep the technical documentation. So they can check and learn
quickly if there is complicated problem. They include:
o User Manual
o Service Manual
o Newest program file
o Some important operation guidance
o Learning materials: video
You buy and store some key spare parts of the devices you are selling. So you can do crosscheck
quickly when users raise repairing issue and you are not sure which part is faulty.
