TM 11-5820-890-10-1
The ECCM fill device stores FH data. You will use the fill device to locally load this
data into the RT.
Fill devices are generally issued on a basis of one fill device per
four radios.
P1 connector. Connects to second fill device for fill
device loading.
Function switch. Turns power on and off. Spring-
loaded ZA (zero all) position zeros all data in fill de-
vice when initiate switch is pressed.
Check light. Blinks when data is transferred to RT or
from tape reader to fill device. Also blinks (confirms
that data is present) when select switch position has
data in it and initiate switch is pressed.
Initiate switch. Used (1) to “ask for” data during fill
device loading: (2) to check if select switch position
has data in it: (3) to zero fill device when FUNCTION
switch is set to ZA.
Select switch. Selects which hopset or lockout set
will be stored or transferred. “A” position is used to
transfer all data from one fill device to another. Posi-
tions 1-13 are for hopsets or lockout sets. Positions
T1 and T2 are not used.
J1 connector. Connects to the RT AUD/FILL connec-
tor by using a fill cable.
