RT DISPLAY SIGNALS AND USES

PURPOSE

SIGNAL

SIG

Signal strength is shown as a lighted vertical bar at the left side of the RT

display window; the higher the bar, the stronger the signal. Activation of this

(Signal)

bar advises the operator that traffic is on the net or that an ERF or OTAR

message has entered the radio. Continuous activation of the signal display

bar is an indication of enemy jamming or friendly interference.

LOW HUB

When the Hold-Up Battery (HUB) becomes weak, a diamond-shaped light at

the right side of the RT display will flash; if the HUB is dead or missing, this

light will remain on. This light appears only while the RT display is active.

Some versions of the SINCGARS radio display an "M" near the right side of

the RT display indicating that traffic is being sent over the net.
