On August 1, 2025, China’s mandatory national safety standard GB 3836.16-2024, Explosive Atmospheres — Part 16: Electrical Installations Inspection and Maintenance Specification, officially came into effect, replacing GB/T 3836.16-2022. The standard applies to locations where explosive gas or dust mixtures with air, or layers of combustible dust, may create hazardous conditions under atmospheric environments, and specifies general requirements for the inspection and maintenance of electrical installations.

As critical communication equipment used in hazardous locations, intrinsically safe radios require systematic inspection and maintenance to support continued compliance and safe operation. The implementation of the updated standard has further increased the need for professional inspection, maintenance, and repair services.

Building on extensive technical expertise, manufacturer-authorized quality control practices, and a nationwide service network, Dynercomm provides customers with professional, compliant, efficient, and reliable inspection, maintenance, and repair services—guided by national standards, supported by professional qualifications, and delivered by experienced technical personnel.

3. Lifecycle Protection Through Professional Inspection & Maintenance

Dynercomm provides visual inspection, close inspection, detailed inspection, periodic inspection, and continuous supervision in accordance with the requirements of the updated standard, covering critical stages throughout the equipment lifecycle.

The following standardized inspection services are available to support safe and reliable equipment operation.

• Visual Inspection
  A visual inspection identifies readily apparent defects through direct observation without the use of access equipment or specialized tools.
• Close Inspection
  Building on the visual inspection, a close inspection uses appropriate access aids or simple tools, such as flashlights or magnifying devices, to identify externally visible defects in greater detail.
• Detailed Inspection
  Building on the close inspection, a detailed inspection may involve opening the enclosure of an intrinsically safe radioand, where necessary, using professional tools and test equipment to identify defects and evaluate equipment condition more thoroughly.
• Periodic Inspection
  Systematic and standardized routine inspections are conducted on intrinsically safe radios, systems, and installations at defined intervals to identify potential issues and help maintain safe and reliable operation. In general, the inspection interval should not exceed three years.
• Continuous Supervision
  Continuous supervision is carried out by experienced professionals familiar with the specific equipment and its operating environment. It includes ongoing care, inspection, monitoring, servicing, and maintenance of intrinsically safe radios to help ensure that their explosion-protection characteristics remain in an appropriate condition.

5. Value-Added Services

• Regular Inspection Services
  Dynercomm places strong emphasis on customers’ long-term operating experience and provides on-site inspection services according to individual customer requirements.

  Tiered inspection service programs are available for different customer needs, providing comprehensive preventive inspections of Motorola professional radio systems and indoor wireless signal coverage systems under non-fault conditions.

  Inspection services may include, but are not limited to, hardware inspection, functional and operating-condition checks, server status assessment, equipment cleaning and dust removal, performance optimization, and database maintenance.

  Regular inspection plays an important role in identifying and addressing potential issues before they develop into equipment failures. This helps improve system stability and reliability, extend equipment service life, and reduce long-term maintenance costs.

  Following completion of an inspection, Dynercomm provides a written inspection service report containing the inspection results and recommended maintenance actions.

• Spare Parts Inventory Services
  Dynercomm provides customers with professional spare parts inventory services, with spare parts categorized into wear-prone components and critical spare parts.

  Wear-prone components refer primarily to products or components whose performance parameters may deteriorate over time or under frequent use. During routine system inspection and maintenance, these components require particular attention and periodic testing of key performance indicators.

  Critical spare parts are components essential to continued system operation. Adequate availability of these parts is important because, if a critical component fails, a compatible replacement may need to be installed promptly to restore normal system operation.

  If an original equipment manufacturer discontinues a product and the corresponding spare parts are no longer available, Dynercomm is committed to providing an appropriate alternative solution and replacement equipment of a comparable specification and performance level.

• Professional Technical Training Services
  Building on Dynercomm’s extensive technical expertise and the training experience of its engineering team, the company has developed a comprehensive professional training program and curriculum covering its communication products and solutions.

  The training program is designed to improve customers’ overall understanding of professional wireless trunking communication systems, familiarize users with standardized operating and management procedures, and develop practical capabilities for everyday equipment operation and maintenance.

  Training can cover dispatch equipment operation, network monitoring and management systems, routine system maintenance, and correct operation and use of radio terminals, helping customers strengthen internal technical capabilities and improve system management efficiency.

• Technical Response & Support Services
  Dynercomm regards customer satisfaction and long-term trust as important measures of service quality and has established a dedicated after-sales technical support system.

  Customers have access to a 24/7 technical support hotline, together with online technical and application support through WeChat and email.

  Technical incidents are handled according to defined priority levels. For urgent P1 incidents or high-priority P2 incidents, Dynercomm recommends reporting the issue through the service hotline to help ensure that critical information is received promptly.

  Customers with an active Dynercomm maintenance service agreement may also receive access to dedicated support channels and enhanced service levels, depending on the applicable service plan.

• Extended Warranty Services
  Standard equipment warranties are typically limited in duration and may not fully address customers’ long-term maintenance requirements. To provide greater lifecycle support, Dynercomm offers extended warranty services for professional radio systems and terminals based on customer needs.

  Customers may extend the maintenance and service coverage of eligible system equipment and terminals by up to three additional years, helping reduce the financial uncertainty associated with unexpected repair costs.

  Extended warranty services also help customers plan maintenance budgets and equipment lifecycle decisions more effectively.

  For customers who purchase eligible extended warranty services, Dynercomm commits to completing equipment inspection and repair within five working days, excluding transportation time. Repair periods for certain system equipment may require additional time depending on the equipment type and technical requirements.

  Through professional inspection, standardized repair, genuine spare parts support, preventive maintenance, technical training, rapid response, and extended warranty services, Dynercomm provides a comprehensive lifecycle service framework for intrinsically safe professional communication equipment—helping customers strengthen compliance management, improve equipment availability, reduce operational risks, and maintain reliable communications in demanding industrial environments.
