Here is one of my original Oceanic transmitters, SN prefix BM, manufacture date 04/12, no manufacture date on sticker
Here is the replacement transmitter I just received, BM SN prefix. Manufacture date of 07/19, but with an R suffix. Manufacture or something date on over-sticker of 07/20 with an R prefix
I couldn't stand it and took the over-sticker off. Now the manufacture or something date on the sticker matches 07/19 with an R prefix
My initial transmitter purchase was in 2010, I have the serial number, but did not record the SN prefix or the manufacture date. I sent it for replacement in 2017. The 2017 transmitter was recently sent in exchange for the one pictured above. I have the SN for that transmitter also but did not record the SN prefix or the manufacture date. I am quite sure that the manufacture date had no R suffix or prefix. The sticker label was long gone.
So, what have I learned, not much. The R suffix or sticker prefix may represent refurbished transmitters. Who knows when they may have started this practice, i.e. not present on my 2017 replacement. Perhaps my current replacement was refurbished twice, 2019 and 2020?
Yes,
@Joneill is correct, they make replacement with units that are already available. From Oceanic Service:
** Note: As the Full Service and Calibration processes for digital and analog instruments may take a number of weeks to complete, depending on our manufacturing department’s backlog, we typically replace returned units with similar instruments that have already undergone the Full Service and Calibration process. This allows us to turn a repair around in a matter of days, rather than weeks, while still insuring that the instrument is factory-new and completely within specification when it leaves our facility. Dive computer logs are erased.
Sorry, see that Brian has already responded to the last point
