The radio can be switched into Transmit Inhibit should the user enter a RF sensitive area (e.g.
a hospital). This mode is indicated by the tri-colour LED rapidly flashing amber 4 times at
approximately two second intervals and the display of the transmit inhibit icon in the top right
hand corner of the screen.
In this state, the radio does not transmit under any circumstances in either TMO or DMO,
except when using the emergency key if customised to do so. The radio remains on the
selected group and in some circumstances can still receive conversations from this talkgroup.
The radio can automatically send a status message to the customised destination when the
radio enters Transmit Inhibit, and again when it leaves Transmit Inhibit.
Use of the emergency key whilst in Transmit Inhibit is supported; however, the time to set up
the emergency call could be increased by a few seconds.

When fitting the antenna, do not over-tighten. Do not use the radio without the antenna
attached unless the radio is being used with an external antenna (e.g. on RSM).

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 STP9000 and
STP8000 radios, behind the panel on the lower front of the STP9100, STP9200, STP8100,
STP8200 and STP8X radios and on the rear of the SRH3000 series radios, is used for half
duplex audio. This loudspeaker directs the lou
d 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.
For
STP8X
radios do
not
insert or remove the SIM Card or Micro SD card in a
hazardous environment. When closing the SIM / SD plastic cover tighten the screw to
0.1 Nm. This ensures that a seal is maintained.
For
STP8X
radios a Sepura approved ATEX/IECEx Antenna
must
be used.
The radio must not be operated without an antenna fitted.
Do not
fit, remove or
replace the antenna in a hazardous environment!
To ensure that a seal is maintained between the antenna and the Radio, screw on
antenna until contact is made and follow with a minimum ¼ turn.
