Radios always
in service.

Speak to technical support before shipping the equipment. Tell us the brand, model and what happens during use: does the radio fail to turn on, lose charge, receive but not transmit, have low audio or fail intermittently? This report helps determine which items should be sent with it.

Where possible, identify each unit by its serial or asset number. If the problem involves a battery, charging cradle, power supply or microphone, tell the team so you can agree on which items to send. You do not need to disassemble the radio to describe the problem.

Include a contact responsible for approval and a list of items sent to technical support. Packaging, receipt and return must be previously agreed upon, especially when there is a damaged battery. To organize the shipment, use the form on this page or the channels on the ABC Mais Telecom Contact Us page.

The timeframe depends on the diagnosis, available parts and authorized service. Therefore, a description by phone helps with triage, but does not replace equipment evaluation nor allows confirming the completion date in advance.

Intermittent failures require a detailed report: in which shift they occur, after how much usage time, with which accessory and in which location. Also inform if there was a fall, contact with liquid or recent configuration change. These data help differentiate the reported symptom from a condition that does not appear during a quick check.

Before work begins, confirm the scope, price and applicable estimated timeframe in the technical support proposal. If your operation cannot be without communication, ask about renting radios during maintenance. This option depends on availability and compatibility; backup equipment is not automatically included in the repair.

We service Motorola Solutions and Hytera radios. The assessment considers the exact model and condition of each unit. Radios of the same brand do not necessarily use the same battery, charger, antenna, connector or programming tool.

Send a readable photo of the equipment identification and describe the accessories used. In fleets with different models, indicate which radio has the failure and which continue to function. This helps organize technical support without attributing an entire operation's problem to a single device.

Service for other brands and older equipment depends on parts availability and technical feasibility. We do not promise to repair every model or replace components without an assessment. If repair is not feasible, you can consult our catalog of two-way radios and discuss with the team about a replacement compatible with the intended use, without choosing solely based on appearance.

The warranty conditions for technical support are stated in the proposal and the service documentation, according to the service performed. Before authorizing, check which items will be repaired or replaced, which tests are part of the scope, and how to request an evaluation if the symptom returns.

A repair warranty does not provide unrestricted coverage for every radio component. A later fault may require a new assessment to establish whether it is related to the work performed. Keep the unit identification, approved proposal and guidance you received.

When returning equipment, report whether the problem is the same as before or if a different condition has appeared. Inform changes in battery, accessory, charger, or usage environment. If there is an active factory warranty, notify before authorizing interventions so the team can evaluate the applicable approach, without assuming that all service will follow the same procedure.

Technical support evaluates power supply, audio, transmission, reception, controls, connectors, accessories, and configuration failures. The diagnosis determines the possible repair; it is not correct to indicate the replacement of a board, battery, or antenna based only on the initial report.

For a radio that won't turn on, describe the signs observed on the unit and base. In audio problems, indicate whether the fault occurs in the speaker, external microphone or both. When communication fails only in certain locations, state whether other units exhibit the same behavior.

Not every communication difficulty is a device defect. Coverage and infrastructure also need to be considered within the operational context. If the problem involves multiple teams or areas, ABC can guide the conversation toward a coverage project with repeaters, without presenting this as a required repair. Preventive maintenance organizes inspection and care; corrective maintenance investigates a fault that has already been identified.

The technical support proposal identifies the parts and conditions available for the equipment. We consider the source and compatibility of parts before replacement. Mentioning a brand on this page does not mean every part is in stock or that all models use the same component.

To evaluate battery or charger, also provide the part code when readable. For antennas, microphones and cables, send the accessory identification used. A similar fit is not enough to confirm application. Do not force connectors or make adaptations to try to fix a fault.

As per manufacturer guidelines, equipment with visible damage or abnormal operation should be evaluated before being put back into use. In case of deformed battery or abnormal heating, stop using it and seek guidance on handling and routing. Do not open the battery. The team informs the viable alternative before any authorized replacement.

Yes. The service records receipt, diagnosis, authorization and completion. The team informs about the progress through the agreed channels. The sequence illustrated on this page explains the technical support process; it is not a real-time tracker for a service order.

To check a unit, have your identification and the service reference at hand, when provided. In shipments with several radios, indicate which equipment you wish to follow up. Two units sent together may have different diagnoses, parts needs and deadlines.

Keep a person responsible for approval and communicate changes in phone or email contact. Before return, check the items that will come back and usage guidelines. If the company operates on shifts, relay this information to whoever delivers and receives the radios. The service history helps avoid losing the failure report between different departments and responsible persons.

Yes. ABC Mais Telecom is located in São Bernardo do Campo, in the Greater ABC region, and shipping for technical support can be arranged with companies from other regions. The shipment and return must be aligned before dispatch, considering the equipment and accessories involved.

Confirm the receiving address, the responsible person and the identification that should accompany the packages. Register the list of radios, batteries, bases and other items sent. Do not send an additional accessory without notifying: a clear list facilitates checking what left your company and what arrived for evaluation.

Inform if your operation has a critical date, such as an event, scheduled stoppage or contract start. This allows discussing the service without promising a deadline that still depends on the diagnosis. For a site visit, please consult address and hours of operation and combine with the team. Costs, transportation conditions and return must be confirmed for each shipment.
