Outdoor displays: 1 year. Indoor displays: 3 years. Both warranty periods begin on the shipment date.

Keep the order reference, selected model and shipment record with the service request. The period is calculated from shipment, so retain the actual shipment date when preparing a warranty enquiry.

RUILED provides return-to-factory repair service, video assistance and remote technical support. Send the order reference and fault evidence so the applicable coverage and service action can be reviewed.

Keep component identifiers and the reported fault together. Do not assume that coverage for a part also includes every local task needed to replace it.

Freight costs are borne by the customer. Confirm the shipment instructions and freight arrangements before sending equipment for repair or arranging a replacement.

Customs handling, local labour, lifting or access equipment, site attendance and commissioning need to be agreed separately where relevant. Include those responsibilities in the order terms or case-specific service proposal.

After the warranty period, service is charged at prevailing market rates. Confirm the proposed work and quotation before proceeding. Freight costs are borne by the customer. Ask for an assessment of the reported issue and the available repair or replacement options.

Availability for an older product needs to be checked. Keep the original model and configuration records so a replacement proposal can be assessed against the installed system.

Provide the order documents, fault evidence and relevant operating or incident history. Ask which exclusions and service conditions apply to the specific agreement.

If equipment has been damaged, modified or serviced previously, describe what happened. Coverage should be reviewed against the written terms and case evidence rather than assumed from a photograph.

Complimentary spare parts are provided at 1% by quantity. The applicable items and quantity breakdown are specified in the order.

Review the required modules, power components, receiving equipment, cables and layout-specific accessories against the selected system. Confirm which items make up the included allowance and quote any additional stock separately. Consider access difficulty, local service skills and replenishment needs when planning extra spares.

Provide the original part identifier, model, relevant hardware revision and position in the display. Ask what matching, calibration or configuration information is required for the proposed replacement.

The same outside dimensions do not establish compatibility. Keep the 500 × 250 mm RUFO and 480 × 320 mm FAB module ranges as separate product records.

Agree the correct part, service procedure, tools, trained personnel, safe isolation and access method for the selected product. Confirm any configuration backup or restoration requirements with the responsible technical team.

Internal electronics work should be performed by qualified personnel. Follow the applicable instructions rather than treating a general website guide as a component-replacement manual.

Keep the final cabinet layout, component list, approved configuration files where applicable, supplied manuals, agreed service instructions and spare-stock inventory together.

After a replacement, record the affected position, old and new identifiers, date, action and verification result. Update the spare-stock count and arrange replenishment as needed.

Video assistance and remote technical support are available. Describe the task, controller/player model, software version and symptoms first. Have a suitable local contact available and agree the session and scope.

If remote access is agreed, authorise the specific session and keep a local operator present. Do not place unattended-access passwords in a website enquiry. Record any approved configuration changes and retain the agreed backup.

Describe the audience and tasks: assembly, content updates, operation, fault reporting or component service. Ask which documents, demonstrations or training arrangements are available for the selected product.

Confirm the format, language, participants, scope and any charges in the proposal. Operator guidance and qualified electrical or structural work are different responsibilities.

Share the country, location, required work and proposed dates. Ask whether a suitable on-site arrangement is available and obtain a defined scope before making travel or site commitments.

Agree local responsibilities, personnel requirements, travel, accommodation, access equipment, charges and scheduling where relevant. Include the approved site-service arrangement in the project scope.

Monday–Friday, 09:00–19:00 Beijing time (UTC+8). Saturday and Sunday support requires advance appointment.

Initial response within 2 hours during working hours and within 12 hours outside working hours. Weekend support requires advance appointment. These timings refer to the first response; repair completion and parts delivery are assessed for the case.

State the deadline, affected function and any local spare stock or backup display available. Provide the model and evidence with the first report so the urgency can be assessed in context.

Confirm the actual response plan and parts/logistics availability for the case. Do not assume a delivery or repair completion time until the relevant arrangement has been agreed.

Record visible display changes, recurring symptoms, unusual environmental conditions and any incident. Keep service routes accessible and report concerns to the responsible technical contact.

Set the inspection frequency and operating checks using the approved product instructions and the site’s maintenance plan. Do not open enclosures or inspect live internal electronics as a routine operator task.

Request cleaning instructions applicable to the exact display surface, product and installation. Confirm the approved materials, method and personnel before work begins.

Do not assume a method used for one LED product is suitable for COB, transparent film, a rental cabinet or another surface. Internal work and electrical isolation require the relevant qualified personnel and procedure.

Keep approved configuration and layout records with the system documentation. Before an authorised update, confirm the correct file, software and hardware context and the backup or recovery method.

Record the purpose, date, person responsible and result of each change. Avoid applying an unknown receiving-card file or resetting a system while trying to describe a fault.

Record any damage or reported symptom, check the agreed parts and accessories inventory, and update the maintenance history. Follow the applicable handling and storage instructions for the product.

After service, review the agreed operating checks and representative content, record the result and replenish any used spare stock. Keep unresolved observations attached to the same service record.
