The BP410 is a rugged, light-weight, ergonomically designed beltback to be used with the BS410 base station. Single-channel operation allows any four beltpack and/or all-in-one wireless headset uses to engage in simultaneous, full-duplex communication. In dual-channel operation, three users may be in full-duplex with up to 13 additional users in listen-only mode. The BP410 has a rugged, over-mold, reinforced casing and long-lasting keypads with no mechanical switch. Using the BAT50 Li-Ion battery, the BP410 has up to 12 hours of battery life.
