FAQ
Which Hytera radios does the SM50M1 work with?
The SM50M1 connects through the Hytera commercial accessory port and is listed for iSeries portables such as the PD402i, PD482i, and PD502i, along with BD5-series radios. The exact fit depends on your radio's connector. Confirm your model with our team before ordering, and we will verify the connector and firmware fit for your fleet.
Does the waterproof rating change when I plug in an earpiece?
Yes. On its own, with the audio port cover closed, the SM50M1 is rated IP67 for dust and short water immersion. When you connect a receive-only earpiece to the 3.5 mm jack, the sealed rating drops to IP54, which protects against dust and splashes. Keep the port cover closed whenever no earpiece is in use.
