Replacement of the Motorola GM microphone: how to order a suitable MDRMN4025

GM340.ru · updated 12.10.2026

First, define the boundaries of replacement.

A missing microphone, a damaged body, inconvenient placement and a problem of speech transmission are different grounds for treatment. Write down what exactly is required: to staff the station, replace a known faulty accessory or deal with the symptom. The wording affects the composition of the application: for an unknown reason of silence, one purchase of a microphone may not be enough.

If the task is to replace a confirmed faulty accessory, specify its code and model of the station. If another placement in the machine is required, further describe the operator’s place of work and the existing mount. The length of the cord, fastener and compatibility are not assigned under the common name "Motorola GM".

Five photos that replace long correspondence

1. Radio nameplate with full designation.
2. Mark the old microphone, if it has survived.
3. The microphone plug so you can see the connection.
4. The station's nest without self-disassembly.
5. Common installed kit, including adapter or external unit.

Link the pictures to a specific machine or inventory number. In a mixed park, it's easy to take photos of two different jobs in one set. If the marking is erased, write: the seller needs data for identification, not a guess instead of a code.

Agree the sample before ordering a large batch

It is convenient for the party to allocate one typical set and coordinate the proposed accessory with it. If there are several models or adapters in the fleet, there will be several standard sets. The result of the selection fix for each option separately: a positive check of one device does not prove the conformity of all the others.

Why not combine the microphone and power supply

The handheld microphone, power cable and accessory connector solve different tasks. If the HKN4137 cable is required at the same time, make it a separate line and confirm the compliance of the specific station. Don’t add it automatically to every microphone replacement: an existing machine can have a full power supply line.

For the same reason, no handheld microphone from a nearby card is suitable. The MDRMN4025 is listed in the GM series accessories catalog; the GMN6146 manufacturer describes for automotive adapters. The selection is based on the installed set and documentation, and not on the similarity of appearance.

How to make a replacement without losing information

After agreeing, save the entry: "machine / station model / microphone code / kit / inspection date." Add a photo of the marking of the supplied accessory and a snapshot of the connection. This is useful for the next replacement and helps to separate the new order from the old unconfirmed order.

Upon receipt, compare quotation, product designation and scope of supply. If the code or kit is different, find out the compliance before issuing accessories to drivers. For several branches, include addresses and quantity for each place of receipt in the general statement.

What to send to us

Then the quotation will be tied to your equipment. The current availability, condition of the product, composition and delivery conditions are confirmed by a specific order; the catalog photo does not determine today's availability.

Order and city of receipt

If the point of receipt is Kazan, Yekaterinburg or Omsk, specify the city and address in the application. For another city of Russia or Kazakhstan, we also agree on the terms in the quotation. The cost, available quantity, composition and term are confirmed for a specific order.

Questions before ordering

Is a photo of the microphone body enough?

For accurate selection, you also need a model of the station, marking of the accessory and photos of the connection. If you have an adapter, enter its code.

Do I need to change the power supply cable with the microphone?

These are separate positions. The cable is added to the order at your own need and after checking the configuration station.

Can I order one microphone to check in front of the batch?

In the application, you can separately specify the need for a sample and a subsequent batch. Opportunity, conditions and configuration are agreed in the quotation.
