How do I tell which model of LD900 I have?

The product label on top of the LD900 will indicate the model, with the system available in three models:

LD900L (L-band)
LD900 (L-band & GNSS)
LD900M (L-band, GNSS & MF)

If the product label is missing, the model can be determined by checking the display. The Status page of LD900L models will feature beam tracking information only:

If Corrections can be seen on the Status page, the unit will be either a LD900 or LD900M model. If MF is not shown under Corrections, the system will be a LD900 model. If MF is shown under corrections the unit will be a LD900M model:
