6.4.1.6 Tactical Mode
When a transceiver is operating in Tactical mode it behaves similar too, and has all the functionality of,
previous generations of Cobham (Wulfsberg) tactical radios, such as the C-5000/RT-5000 and P-2000.
This includes preset channel tuning, P25 functionality, and, via the Manual-Channel, unlimited frequency
tuning capability. The following sections describe operation in Tactical mode.
6.4.1.6.1 Changing Channels
When the unit is operating in tactical mode and standby tuning is enabled and the operator presses the
Transfer-Button the active and standby channels shall be swapped, and the active transceiver shall be
tuned to the new active channel (previously the standby channel). Figure 19 depicts the active
transceiver both prior to, and after, pressing the Transfer-Button.
