6. Firmware Programming Mode
6-1. Preface
Flash memory is mounted on the TK-280. This allows the TK-280 to be upgraded when new features are released in the future. (For details on how to obtain the firmware, contact Customer Service.)

1. If you press the [MON] switch (top of left side) while "PROG 57600" is displayed, the version is displayed. If you press the [MON] switch again while the version is displayed, "PROG 57600" is redisplayed. 2. If you press the [CALL] switch (bottom of left side) while "PROG 57600" is displayed, the display changes to "PROG 19200" to indicate that the write speed is low speed (19200 bps). If you press the [CALL] switch again while "PROG 19200" is displayed, the display changes to "PROG 38400", and the write speed becomes the middle-speed mode (38400 bps). If you press the [CALL] switch again while "PROG 38400" is displayed, the display returns to "PROG 57600". 3. If you press the [CALL] switch while the version is displayed, the checksum is displayed. If you press the [CALL] switch again while the checksum is displayed, the version is redisplayed. Note: Normally, write in the high-speed mode.

6-2. Connection procedure
Connect the TK-280 to the personal computer (IBM PC or compatible) with the interface cable (KPG-36). (Connection is the same as in the PC Mode.)

7. Clone Mode
Programming data can be transferred from one radio to another by connecting them via their external universal connectors. The operation is as follows (the transmit radio is the master and the receive radio is a slave).

6-3. Programming
1. Start up the firmware programming software (Fpro.exe). 2. Set the communications speed (normally, 57600 bps) and communications port in the configuration item. 3. Set the firmware to be updated by File name item. 4. Turn the TK-280 power ON with the [A] switch held down. Hold the switch down until the display changes to "PROG 57600". When "PROG 57600" appears, release your finger from the switch. 5. Check the connection between the TK-280 and the personal computer, and make sure that the TK-280 Is in the Program mode. 6. Press write button in the window. A window opens on the display to indicate progress of writing. When the TK-280 starts to receive data. the [P] icon is blinking. 7. If writing ends successfully. the LED on the TK-280 lights and the checksum is displayed. 8. If you want to continue programming other TK-280 s, repeat steps 4 to 7. Notes: q This mode cannot be entered if the Firmware Programming mode is set to Disable in the Programming software (KPG60D). q When programming the firmware, it is recommend to copy the data from the floppy disk to your hard disk before update the radio firmware. Directry copying from the floppy disk to the radio may not work because the access speed is too slow. 1. Turn the master TK-280 power ON with the [D] key held down. If the Data password is set to the TK-280, the TK280 displays "CLONE LOCK". If the password is not set, the TK-280 displays "CLONE MODE". 2. When you enter the correct password, and "CLONE MODE" is displayed, the TK-280 can be used as the cloning master. The following describes how to enter the password. 3. How to enter the password with the keypad; If you press a key while "CLONE LOCK" is displayed. the number that was pressed is displayed on the TK-280. Each press of the key shifts the display in order to the left. When you enter the password and press the [�] key, "CLONE MODE" is displayed if the entered password is correct. If the password is incorrect, "CLONE LOCK" is redisplayed. How to enter the password with the encoder; If the encoder is rotated while "CLONE LOCK" is displayed, numbers (0 to 9) are displayed flashing. When you press the [D] key, the currently selected number is determined. If you press the [CALL] key after entering the password in this procedure, "CLONE MODE" is displayed if the entered password is correct. If the password is incorrect, "CLONE LOCK" is redisplayed. 4. Power on the slave TK-280. 5. Connect the cloning cable (No. E30-3325-05) to the universal connectors on the master and slave.
