Request composition and delivery

When replacing a satellite compass, it is important not to re-purchase a serviceable part and at the same time not to leave the inappropriate one. For JLR-21, start with a list of existing blocks: what is established, what is faulty, and what is planned to be saved. Such a request allows for agreement on the subject of delivery before the equipment is removed from the ship.

Two blocks, two lines of the statement

In the documentation JRC system JLR-21 sensory NNN-21 display NWZ-4701. The processor is built into the sensory part. Therefore, the antenna photo does not describe the entire order, and the display designation itself does not prove which sensor and what accessories will be supplied.

The price in our list is 660,000 RUB. The actual composition of the quotation, the condition of the equipment and accessories are confirmed by the specification. We do not consider any option from the factory brochure automatically included in this amount. If you only need a specific block, it is a separate request with confirmation of availability and price.

What can be saved

The decision is made by the service organization on the exact designations and condition of the parts. For initial calculation, send photos of markings, track lengths and a list of connected data consumers. Especially useful are the images of the connectors from existing cables and information about previous replacements.

Leaving an old cable just because it's already laid is not enough. It must correspond to the desired connection and be suitable for further work. Similarly, the same appearance of the units does not confirm the compatibility of different generations of equipment.

Date - separate acceptance point

JRC issued a GPS rollover notice for JLR-21/31 with a date of August 3, 2025. It describes the possible return of the calendar date after certain actions, including the reset or replacement of the internal battery. This is a reason to check the date and service history of a particular instance, rather than declaring any such system malfunctioning.

The application can include a requirement to confirm the correct date and time in the agreed inspection. If the device has been serviced after the battery has been reset or replaced, please let the service know. The order of setting is taken from the manufacturer's documentation; random operations for checking before buying are not necessary.

Boundary of supply and work

Separately determine who performs dismantling, connection, verification of data exchange and registration of the result. The price quotation of equipment does not include these works silently. Additional cables and mounting accessories are also explicitly listed so that the total amount relates to the agreed set.

Specify the amount, the city of receipt and the date required. For delivery to the repair site, it is useful to appoint the recipient in advance and transfer the statement to him. At acceptance, markings, completeness and documents are compared, then the equipment is transferred to specialists for connection. So the order, the actual delivery and the task of replacement remain linked.

Questions before ordering

660 000 RUB is the price of any configuration option?

Nope. This is the quotation price from the list provided. The actual composition and condition are specified in the specification; a separate unit or additional accessories are agreed separately.

Can I leave an old display or cable?

The ability to save is checked by accurate models, versions, connections and condition. The same appearance is not a confirmation of compatibility.

Why check the calendar date?

The manufacturer has a GPS rollover notification for JLR-21/31. Acceptance of a particular instance should take into account the date, time and history of service.

The main product is listed first. The other compass is selected separately for the task; its blocks are not automatically compatible.

Delivery in Russia and Kazakhstan. The cost and delivery time are agreed on by the city and the composition of the order. The actual availability, condition, documents and completeness are confirmed in the quotation. The information is not a public offer.
