Check the BJC circuit pack to see if
the green LED is extinguished and
the yellow LED is lit. If so, perform
the following steps:
1. Reset the BJB microprocessor
board and see if the problem is
resolved.
2. If the problem recurs, replace the
BJC board.
3. If the problem remains, call your
local RTAC representative.

If the front panel LCD module,
LEDs, or switches fail, perform the
following steps:
1. Verify that the ribbon cable from
the backplane to the display is not
cut, abraded, or otherwise
mangled. Replace the cable if
damaged.
2. Reset the BJB microprocessor
board after replacing the cable but
before retesting.
3. If the problem remains, replace
the BJE alarm relay/display board.
4. If the LCD module is still not
functioning, but LEDs and
switches are working, replace the
LCD module; if the switches and
LEDs are still not operating,
replace the BJG board.
