4.5.1 RSSI, Tx Power, Temperature Status (Mode 2, 3 , 4)
Front panel modes 2, 3, and 4 all display a bar graph to indicate the level of RSSI, transmit power, and
temperature respectively. The top LED that is lit indicates the current value, if the LED is lit green then the
value shown in Table 3 applies, while if the LED is lit red then the current value is half way between the
listed value in Table 3 and the previous value.

NETWORK LINK
When network link is green it shows that the unit can hear a remote radio that is on the same network and
hopping pattern. Slave radios should show network link constantly, as master radios are constantly
