• User Mode
This mode allows you to operate the TKR-750/850/
751/851 as a base station or repeater. The TKR-750/
850/751/851 automatically starts up under User Mode
when turning it ON while data is correctly configured.
In this case, you do not have to press any keys. You
can configure a base station function or repeater
function on each channel. (Refer to 4 Channel
Information.)
With this mode, DSP program in a internal flash
memory is written to the DSP RAM when turning it
ON. When it is controlling remotely, high/low signal is
entered from an external device via an auxiliary input
terminal, then various functions are activated. (Refer
to 20 Function Port.)
This mode supports DTMF Air Remote function.
(Refer to 17 DTMF, 18 Remote Control.)
• PC Mode (Refer to 24 PC Mode.)
PC Mode is a mode activated after starting up under
the User Mode and this mode is controlled with
commands entered through a PC. Data
communication is made through the microphone
connector (8-pin connector) located on the front
panel or the control interface jack (25-pin connector),
which is in conformity with the RS-232C standard
located on the rear panel. The baud rate of data
communication is 9600 bps. (Refer to Table 1-2
Assigning signals to 25-pin connector.)
• PC Programming Mode (Refer to 24.1 PC
Programming Mode.)
This Mode is activated by the PROGRAM command
sent from a computer and allows you to read or write a
configuration data between FPU and TKR-750/850/
751/851.

• PC Test Mode (Refer to 24.2 PC Test Mode.)
The PC Test Mode is a mode to activate by the
TUNING command sent from a computer, and in this
mode, you can control transmission and reception by
the computer.
• PC Tuning Mode (Refer to 24.2.3 PC Tuning Mode.)
This mode allows you to adjust various transmission
and reception adjustment under the PC Test Mode.
• Firmware Programming Mode (Refer to 25 Program.)
You can program a firmware update in this mode. You
are able to program the firmware using a special
software (FPRO.EXE) and a programming speed is
115200 bps, 57600 bps, or 38400 bps. The DSP
software is also written into a flash memory.
