Selected FPF line is now unused.
ACTION: Select appropriate FPF line having stored data.
GUN IS ADJUSTED
Adjustments have already been completed for this weapon.
ACTION: Select new weapon to adjust only after all adjustments have been completed for the
current weapon. Once new weapon is selected, previous adjustments are fixed and further
adjustment is not permitted for weapon currently in use.
ID ASSIGNED
This KNPT number or TGT number entry has already been used.
ACTION: Choose alternate number for data storage, or delete stored data before storing
new data.
ILL ENTRY
Illegal value entered into blank field of data entry menu.
ACTION: Determine proper value range for data and change data entry accordingly.
ILLEGAL CHARGE
Manually entered charge is invalid for selected ammunition.
ACTION: Leave charge field blank (MBC selects optimum charge) or enter valid
alternate charge.
ILLEGAL SWITCH
Invalid keypress.
ACTION: Check entry. Make only valid entries.
ILLEGAL TGT NUM
Target number is within target number block range assigned in SET UP.
ACTION: Manually enter a target number outside range defined in SET UP, or notify
sender to retransmit valid target number.
INST:FAIL
Processor failure.
ACTION: Return MBC to next higher maintenance level.

EXPLANATION and ACTION
MAX
NOT
MAX fire line is closer than MIN fire line.
GREATER
ACTION: Verify MIN and MAX fire line entries.
MODEM:FAIL
Modem CCA failure.
ACTION: Return MBC to next higher maintenance level.
MSG
BUFFER
No messages are stored in message buffers.
EMPTY
ACTION: DO NOT press MSG switch unless message lamp is blinking.
MSN
#
Unassigned mission selected for activation.
UNASSIGNED
ACTION: Activate an alternate mission when operating on a previously initiated
mission.
MSN ERROR
Probable MBC software fault.
ACTION: End mission and reenter. Compute mission. If error reoccurs, return MBC to
next higher maintenance level.
N TOO BIG
Computed delta northing exceeds 32767.
ACTION: Verify all entries affecting delta northing. Also, verify that MIN E and MIN
N entries in SET UP data are appropriate for mission coordinates.
NO ACTIVE MSN
No missions are stored in mission buffers or no mission is presently activated.
ACTION: Initiate new mission using GRID, SHIFT, or POLAR switch or FR message;
or select a stored mission using MSN switch and appropriate display switch.
NO ADJUST DATA
All required adjust data have not been entered.
ACTION: Do not press COMPUTE switch for an ADJ before viewing ADJ data entry
field (DEV).
NO AVAIL MSN
Mission buffers are full (three missions stored).
ACTION: Terminate one stored mission by selecting EOM, EOMRAT, or EOMFPF.
Then initiate new mission.
NO CURRENT MET
Current MET has not been initialized.
ACTION: Enter or review appropriate NEW MET data and initialize CURR MET by
pressing UPDATE*, or select STD MET.
NO FO ENTERED
No FO entry in mission input data.
ACTION: When sending digital response to manual input mission, enter FO ID when
beginning mission. FO ID is entered automatically in BMD-supported missions.
NO MAP MOD
Computation (such as computing gun orders) requires MIN E and MIN N coordinates,
and none were assigned in SET UP data entry.
ACTION: Completely initialize SET UP data.
NO OUTPUT DATA
Review of FIRE DATA or SFTY DATA or other operation (such as ADJ, REG, or
REPLOT) requires existing output data.
ACTION: Press COMPUTE switch after properly entering appropriate mission input
data.

Appendix F
ERROR MESSAGE
EXPLANATION and ACTION
NO SHEAF DATA
Special sheaf selected but without width or direction entry.
ACTION: Enter all sheaf data before pressing COMPUTE switch.
NO TGT DATA
Insufficient target location data.
ACTION: Press MSN switch, then sequence through mission input data menus. Enter
all input data on all entry menus.
NO TGT NUM
Target numbers not yet assigned for target block definition in SET UP data.
ACTION: Assign new block of target numbers using SET UP initialization menu
sequence.
NO TRIANGLE
Line segments in SURV INT or RES problem do not converge.
ACTION: Verify input angle and coordinate data entries.
NO WPN DATA
Weapon not yet selected using WPN/AMMO switch.
ACTION: Enter weapon on WPN select menu before pressing COMPUTE switch.
POWER FAILURE
MBC powered down by means other than ON/OFF switch, such as by removing battery
or external power.
ACTION: Turn power off using ON/OFF switch before disconnecting power source.
PTS AVAIL:##
Remaining number of points available in fire zone storage buffer when new fire zone
entry contains too many points.
ACTION: Define new fire zone with fewer points or delete unused fire zones to
provide additional buffer storage space.
RAM:FAIL @##
IMICRO test random access memory failure.
ACTION: Return MBC to next higher maintenance level.
RANGE
TOO
Range to target is zero, or when entering FIRE ZONES data, distance between points is
SMALL
less than 10 meters.
ACTION: Verify mission input entry or FIRE ZONES data entry.
REG TOO BIG
Range corrections exceed 999 meters when computing a registration.
ACTION: Register target only when range corrections are 999 meters or less (usually
much less).
REV NO. FAILURE

ERROR MESSAGE
EXPLANATION and ACTION
SAFETY
Impact point is outside defined safety fan boundaries.
VIOLATION
ACTION: Verify target location and safety data entries. Reenter, if necessary. No
further action can be taken.
SINGLE WPN ONLY
More than one weapon is designated on TFC sequence GUNS: @# ________ menu but
selected TFC CONtrol allows only one weapon.
ACTION: Select TFC CONtrol function allowing multiple weapons, or DO NOT enter
additional weapons.
SPC SHEAF ERROR
Weapon registration is illegal while in TFC CONtrol (SPECial SHEAF).
ACTION: To perform a registration, change TFC CONtrol selection.
SUPERSONIC
Calculated shell velocity exceeds mach 1.
ACTION: Prevailing nonstandard conditions provide inaccurate MBC calculations.
Verify all nonstandard initialization entries including AMMO powder TEMP, AMMO
weight corrections, all MET data, and target and weapon ALT.
TEMP OUT OF
Powder temperature entry outside range (-70 to 140).
RNGE
ACTION: Verify that powder temperature entry is within allowable range.
TEMP TOO LOW
MBC cannot compute gun orders for 107-mm mortars with extension when powder
temperature is below -30 degrees.
ACTION: Mission cannot be fired under given conditions. Verify ammunition powder
temperature and target location entries.
TEMP TOO LOW
Air temperature in MET data is below 1536 (153.6 degrees Kelvin or -183.2 degrees
Fahrenheit).
ACTION: Verify that air temperature entry is 1536 or above.
TGT HIGH/RN BIG
Target is beyond maximum range or maximum altitude at maximum allowable safe
charge, and charge has not been manually entered.
ACTION: Mission cannot be fired under given conditions. Verify WPN/AMMO and
target location entries.
TGT
LOW/RN
Target is below minimum range or minimum altitude at minimum allowable safe
SMALL
charge, and charge has not been manually entered.
ACTION: Mission cannot be fired under given conditions. Verify WPN/AMMO and
target location entries.
TGT TOO HIGH
Target altitude is greater than 90 percent of MAX ORD of computed flight trajectory.
Reliable results cannot be obtained.
ACTION: Increase charge or elevation entries, if possible.
