Sepura plc has engineered an innovative audio solution for the radio. Duplex audio (for
telephone type calls) and the half duplex audio (for radio calls) are directed to different
loudspeakers.
Duplex audio is routed to the low power Duplex Earpiece on the front of the radio. A more
powerful loudspeaker, situated behind the alpha-numeric keypad on the STP8000 radios,
behind the panel on the lower front of the STP8100 and STP8200 radios and on the rear of
the SRH3000 series radios, is used for half duplex audio. This loudspeaker directs the loud
audio away from a user‟s ear should the user accidentally answer a half duplex call as though
it were a duplex call.
WARNING:
Hold the radio close to the ear only when making, or receiving, duplex calls.

If the radio is used in extremely heavy rain it is possible that some water may seep
behind the keys on the keypad. This will not harm the radio but may reduce the
volume of the loudspeaker. If this occurs it may be easily remedied by holding the
radio firmly and shaking it once or twice to remove the water.
