Service diary, February 25

Outbreaks continue, relevant state ministries and commissions and local government introduced a series of supporting enterprises, project to return to work and production, policy measures to promote the economic and stable operation, is also gradually restore construction of highway engineering construction industry, major projects have been started, who has road just holding group equipment (group), I wish you all good luck in the old and new users start!

Customer service center during the outbreak of service uninterrupted, through a number of service measures to assist users to participate in the anti-epidemic project construction, in order to understand the upcoming resumption of user equipment use and actual demand, through the E, wisdom & throughout; All customer service engineers are online 24 hours a day to answer calls and reply messages at any time, providing timely and effective services for overseas and domestic users, especially for participating in the construction of each region. Xiaotangshan & throughout; Users of hospitals and major highway construction projects provide support and security.

At the same time, after-sales team also many times video work meeting, summarize all around for a long time in ten years after-sales service line of actual combat experience, creating multiple devices common faults and maintenance technical guidance and a short video, through constant communication with customers, we are delighted to hear and see more and more users have been or will be on the road to return to work, here, to just road just holding group equipment (group) customer service center for partners on a return to work first boot check tips.
