DM4600
Mobile Radio in the DM family. Bands VHF/UHF/300. Channel capacity 1000. Ingress protection IP54.
Regional naming
This catalogue lists it as DM4600; in Asia it is sold as XiR M8660, in North America it is sold as XPR 5550, and in Latin America it is sold as DGM 8500. Why one radio carries four names.
The unit we photographed is labelled AZM28QPH9RA5AN on the nameplate. Quoting that code when you ask for a price is the surest way to be quoted the same build.

Parameters
Every row carries a source position. Rows without a recorded source stay visibly empty until verified — that is the intended state, not a rendering fault.

Energy and accessories
No energy item recorded against this identifier yet
Battery fitment is recorded per model, and this model has no recorded pairing. It does not mean that no battery fits — it means the pairing has not been verified yet.
Ask for the fitment to be confirmed with the quotation.Regional naming
Regional builds differ
A regional counterpart is a naming relationship, not a substitution. Firmware, band split, keypad layout and regulatory marking differ between regional builds. Confirm the ordering code for your market before committing to a purchase order.
Price and lead time
There is no list price on this page. The same identifier is quoted at different prices depending on what ships with it, and a figure without those terms cannot be compared with the next quote you receive.
- Band build. The band and sub-band decide what the unit can do on your licence, and they are settled when the unit is built.
- Energy item. Capacity, and whether a charger is in the box, changes the unit price more than most buyers expect.
- Accessories. Antenna, earpiece, carry system and programming cable are often bundled by one supplier and itemised by another.
- Quantity. The per-unit price moves at quantity breaks, so a ten-unit quote and a fifty-unit quote are not comparable per unit.
- Delivery term. DDP and DAP differ by duty and clearance, not by freight alone.
- Warranty term. The term and who honours it belong on the quote, not in a footnote.
Send the order in those terms and the reply is a price, not another set of questions.

Most fleets need both, and the ratio is set by counting posts rather than people. Three things change with the form factor: where the antenna sits, what powers the radio, and who signs it out.
- Before you reorder, read the label — not the panel
A family name covers several builds. The label on the chassis is what distinguishes them, and a photograph of it removes the round of questions that a description cannot.
Selection questions
Model names sold in different regions are a naming relationship, not a substitution, so the decision is driven by the market you will operate in rather than by performance. What matters is the ordering code for your destination: firmware, band split and regulatory marking follow the regional build. Publish your destination country and band requirement in the enquiry and we will confirm the code that matches.
Choose the band your licence covers, then buy the hardware to match. In most markets the regulator grants specific frequencies and requires type-approved equipment; ordering a band that your licence does not cover creates equipment you cannot lawfully use. Band availability is recorded per ordering code, not per model name.
Check the serial number against the manufacturer record, compare the battery and accessory part numbers against the build sheet, and inspect the housing for refinishing. Ask for photographs of the actual serial plate before payment, and keep them — the plate, not the listing, is the evidence. We publish condition per batch in the quotation rather than defaulting every line to new.
Only with the transport documentation completed for the specific battery and packing configuration, and many carriers refuse loose lithium cells entirely. Expect a sea or road default for bulk energy items. The transport position is confirmed per shipment, and this site does not present a blanket answer as if it were one.
These four questions apply to every identifier in the catalogue. Programming, shipping energy items, unlisted models and the commercial process are answered on the selection FAQ.
