Emergency Signalling Options
Conventional Digital and Trunking Channels
The KNG portable radio supports P25 Emergency Operation. When
Emergency Operation is engaged the radio will transmit the P25 ID
of the radio along with the required P25 Emergency bit. Emergency
operation applies only to channels programmed for Digital or Mixed
Mode transmissions.
On channels programmed for analog transmissions, pressing PTT in
Emergency Mode will result in a normal analog transmission.
On channels programmed for Mixed Mode transmissions, pressing PTT
will result in a digital transmission, regardless of the position of the ‘TX
Digital’ switch.
All scanning and priority functions will be disabled during Emergency
operation.
Depending on the radio’s PC programmable settings, emergency signal
will be sent automatically or with each Push-to-Talk.
