Eads TGR990 - Transmit Inhibit

Trunked Mode Operation - TMO

Q Transmit Inhibit
You can activate the Transmit Inhibit (TXI) Mode before entering RF
sensitive areas, for example in hospitals or in potentially explosive
areas, where safety can be jeopardized due to TGR990
transmission radiation.
Note: Radiation of the TGR990 is only suppressed if the TXI
Mode is activated or the TGR990 is separated from power
supply.
In TXI Mode the TGR990 will not transmit under any circumstances,
except for the Emergency Call, which can be initiated even if the
TGR990 is in TXI Mode.
All TGR990 functions and keys which cause transmission, for
example registration to the network, change of talkgroup or folder,
sending messages, pressing
PTT , and so on, are disabled.
When no danger to safety exists anymore (for instance if you leave
the RF sensitive area), the TXI Mode can be deactivated and the
TGR990 returns to standard operation.
