Hytera PD78X User Manual

Hunt
In trunking mode, the radio must register with a BS for
normal operation. The radio can adopt versatile Trunked
Station Control Channel (TSCC) strategies to ensure a
quick registration.
Hunt Before Registration
Before registering, the radio hunts through the control
channels for available BSs.
Two hunting plans are adoptable: Fixed Trunking Station
Control Channel (Fixed TSCC) and Flexible Trunking
Station Control Channel (Flexible TSCC).
When the radio has unified frequency plans, it can use
Fixed TSCC to hunt on the control channels in the fixed
list. When the radio does not have unified frequency
plans, it can use the Flexible TSCC to hunt on the control
channels in the flexible list.
The hunt modes available in the Fixed TSCC are as
follows:
