Changes to be made on Ver. 2.22 SPU
The eliminated problems are;
1) Keyboard locks up when the route (in RTE sentence) contains 31 or more waypoints,
including own ship’s number (00).
Note: Maximum 30 waypoints can be processed as one route in FAR2xx7 radar.
When connecting to GP-90 for external route navigation, the number of waypoint
should be 29 or less for one route.
2) Own ship’s vector is not updated when COURSE vector is selected through
[MENU]-9-7-6, while the radar is operating in cross mode in Interswitch function.
3) After CU/RESET operation in CU-Off center mode, the plotter display does not
overlay the radar picture exactly.
4) REVERSE selection of wheel drive through [MENU]-9-7-2 is not backed up when
power is removed.
5) Range ring and Heading line is presented by dot line when Gyro Error is generated.
6) Setting of AUTO STC (STC level) is not restored when PM or SART operation is
turned off.
Changes to be made on Ver. 1.03 DRAW FPAG (0005 in selftest screen)
Following bugs are fixed.
1) The third color bar from the top in the factory test display is displayed in different color.
2) The 12th color of echo trail is presented by darker color.
Changes to be made on Ver. 1.20 RFC
Following bugs are fixed.
1) Tuning search is performed when the pulselength is changed.
2) Check sum is added to the data from the RFC to the SPU.
3) The RFC setups MIC tuning voltage every five seconds.
4) TUNE IND voltage less than 50 % of maximum level is ignored during Tune Tracking
function.
5) RF error due to check sum does not appear even if RFC 1.20 or newer is used with
older version of SPU 2.14 or older. Tentative versions SPU 2.17 gives RF error if the
RFC ver 1.10 or older is connected.
Changes to be made on Ver. 01.22 RFC
Following bugs are fixed.
1) Small search of Auto tuning is activated when the sector blanking area, resulting in the
burred echo. This happens with Ver.2.20 SPU and Ver.2.20 RFC.
2) Gain and STC control is disabled when the mode is changed to STBY, then to TX
within six seconds.

How to read program versions
1. Press [2], [3] and [4] keys in this order while pressing [1:HL OFF] key.
2. Select “4: FACTORY TEST”. The FACTORY TEST screen looks like below.
FPGA program version and RFC program version are displayed as below.
1 2 3
004F 0009 0004
0009 001F
DO NOT use RFC FPGA of Ver.0015. It should be updated to 0017 or 1F (replace RFC
board). With Ver.0015, the data from SPU board may be partially lost at initial power
on.

History of RFC board
As of March 2005, the current RFC board is 03P9346-33A.
When RFC 03P9346-33A (with J806) is used:
- In X-band, J806 is not used (open).
- In S-band having MD board 03P9244-55E, connect J806 to J816 on MD board.
- In S-band having MD board 03P9244-33E, J806 is not used.
When RFC 03P9346-11 (without J806) is used:
- In S-band having MD 03P9244-55E, J816 from 03P9244 is not used. The noise ring
suppression does not work in this case.

How to change DVI I/F board
To replace DVI I/F board;
1. Place the monitor face down on a soft flat surface.
2. Remove 28 screws from the back of the monitor.
3. Unplug CN10, CN14, and CN16 and remove five screws from DVI I/F board.
4. Remove CN1 metal reinforcement from the connector, loosening two Hex screws.
5. Fix the CN1 metal reinforcement onto the replacement board, DVI I/F board.
6. Reverse steps 1 to 3.

How to check modification on Inverter board
Diodes, D23 and D24 are removed from Inverter board to disable low-current protector.
Use the following steps to gain access to diodes.
1. Take steps 1 and 2 on the previous page.
2. Unplug J3 on 03P9360 and CN10 on DVI I/F board.
3. Remove the aluminium cover.
4. Make sure that D23 and D24 are removed. If not, unsolder these diodes.
5. Reverse the above steps.
