5-1 PREPARATION

The receiver (IC-R2) must be adjusted on the adjustment mode after programmed adjustment frequency data into memory chan-
nel. When you program adjustment frequency data into memory channel, optional CS-R2
CLONING CABLE are requird

' ' SOFTWARE INSTALLATION
NOTE: Before using the program, make a backup copy of the original disk. After making a backup copy, keep the original disk
in a safe place.
q Boot up DOS.
w Insert the backup disk into the floppy drive A.
e Type the following to install the adjustment program:
A:\>INSTALL A C:\CSR2 [Enter]
' ' ADJUSTMENT FREQUENCY DATA
When program adjustment frequency data (at right) into memory
channel, back up the original memory data using the optional CS-
R2, OPC-478, and re-program it after adjustment.
CAUTION: When clone the adjustment frequency data to the
receiver, the receiver's memory channel wiil be over-
written the data and deleted original memory data at
same time.
' ' ENTERING THE ADJUSTMENT MODE
q Connect a JIG (see illustration at CONNECTION) to the [SP]
jack.
w Push and hold [FUNC], then turn power ON.
e Disconnect the JIG and connect a PC with an OPC-478.
r Boot up DOS.
t Type the following to start up the adjustment program:
C:\>CD CSR2 [Enter]
C:\CSR2>CSR2 [Enter]
• Main menu appears at the top side of the cloning program,
select the sub-menu "Screen"–"Memory CH"–"Bank 1", then
input adjustment frequency (at right).
y Select "Write –> Receiver" of the Clone on the top menu.
• Application writes adjustment frequency data to the connected receiver.
u Disconnect the cloning cable and turn power OFF, then turn power ON to start adjustment.
' ' OPERATING ON THE ADJUSTMENT MODE
Change the value
Change the channel [UP]
Change the channel [DOWN]
' ' EXITING THE ADJUSTMENT MODE
When the adjustment is finished, the receiver must be cancelled adjustment mode to use normal operation, otherwise receiver
does not work properly.
q Turn power OFF.
w Push and hold [FUNC] and [V/M], then turn power ON.
NOTE: All memory data except adjustment value will be cleared at this operation.
