1-5. Item List in Test Mode
The item list in the test mode used for operation confirmation is described below. To enter each item,
hold down the
[SET]
button. The setting of each item can be switched using
[+]
and
[_]
buttons. There
are items in which the change in setting brings a violation of the law. For the item whose change is
prohibited, therefore, do not change the setting. Turn on the power again when you changed the setting
incorrectly. The change in setting may be able to be recovered.
Entering the test mode
1. Turn on the power of this unit.
2. Move a menu to VERSION.
3. Hold down the
[SET]
button for two seconds or more.
4. Press the
[+]
,
[_]
, and
[+]
buttons sequentially.
5. Lastly, hold down the
[_]
button for two seconds or more.
Exiting the test mode

Item Change Function
MAIN CPU VER-
SION
_
Displays the firmware version of CPU (IC402) on the DPR-396 board.
FPGA VERSION
_
Displays the firmware version of FPGA (IC201) on the DPR-396 board.
REMOTE VERSION
_
Displays the firmware version of remote CPU (IC2000) on the RM-215 board.
CH PLAN VERSION
_
Displays the version of the channel plan built in EEPROM (IC813) on the
TX-172 board.
SERIAL NUMBER
_
Displays the serial number of this unit.
DESTINATION Prohibited Sets the destination of the RF circuit. Change is prohibited.
Not used for maintenance service.
RANGE0 Prohibition
of numerical
change Changes the GAIN of the amplifier circuit of the RF circuit per frequency. The
value cannot be changed. In the service, the transmission frequency can be
changed by moving the screen to B (C), B (L) and B (H) used for the setting
of frequency during the measurement of RF.
