Press the SETUP button located on the front panel to toggle between repeater setup and knockdown,
with LED indications. While in setup state, both radios turn on at power up; in knockdown state, only
receive radio turns on at power up. There are three repeater types: base station, uni-directional and
bi-directional in the repeater setup state. The repeater is initialized to base station mode when it toggles
from knockdown to setup state. But in the knockdown state, the repeater works only as a receiver.
In base station mode, the repeater function is disabled, with the slave radio as a receiver and the main
radio as a transmitter. In bi-directional repeater mode, the front panel PTT is disabled.
The repeater setup/knockdown status will be recorded after the repeater power failure. (E.g. If the
repeater operates in forward directional mode, it will still work in such mode after the power recovers)
PC Programming Mode
Connect the PC with the repeater via programming cable. Data can be transmitted from PC to the
repeater. Repeater LCD displays “PROGRAMMING” while reading/writing data from/into the radio, with
red LED flashes indicating programming the main radio, and then green LED flashes indicating
programming the slave radio. The repeater resets automatically after programming is finished.
