UP-820N/820F (V)   LEAD-FREE SOLDER
 LEAD-FREE SOLDER
The PWB’ s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder. The
alphabet following the LF mark shows the kind of lead-free solder. 
Example:
(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a breakdown or an accident. 
Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use soldering iron is rec-
ommendable. 
(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering capacity is inferior to
conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land separation or may exceed the heat-resistive tem-
perature of components. Use enough care to separate the soldering iron from the PWB when completion of soldering is confirmed. 
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.  
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip after com-
pletion of soldering work. 
If the soldering iron tip is discolored black during soldering work, clean
and file the tip with steel wool or a fine filer.

[MRS1 key & MRS2 key]
Position of MRS1 & MRS2 key is as follows.
MRS1 key : The key located on left upper corner. (B key)
MRS2 key : The key located on right upper corner. (A and B key)
Key board layout
[Secret key operation]
This operation is used as password of MRS operation.
Following key sequence have to enter after operate reset switch.
If you operate wrong sequence then program reset is performed.
a : The key located on right upper corner.
b : The key located on left lower corner. (Flat keyboard)
b’: The key located on left lower corner. (Normal keyboard)
c : The key located on left upper corner.
d : The key located on right lower corner.

Key board layout
Master resetting 1 and 2 can be accomplished by using the following
procedures.
*Meaning of reset switch “ON” & “OFF” positions are as follows.
ON position : The position that CKDC becomes active state 
(Normal status.)
OFF position: The position that CKDC becomes reset state 
(Reset status)
There are two possible methods to perform a master reset.
• MRS-1
Procedure :
Clears the entire memory and resumes initial values.
1) Set the reset switch to OFF position and turn-on the machine.
2) Press and hold the MRS1 key and the reset switch move to ON
position.
3) And then, enter the secret key operation.
• MRS-2
Clears the entire memory and resumes initial values. (Master resetting
2 enables the layout of fixed keys in addition to master resetting 1.)
Procedure :
1) Set the reset switch to OFF position and turn-on the machine.
2) Press and hold the MRS2 key and the reset switch move to ON
position.
3) And then, enter the secret key operation.
Program the 0 to 9 keys, 00 key, 000 key, decimal point key, CL key, X
key, SBTL key, MODE key, cursor keys, HOME key, and CANCEL key
and ENTER key and TL key in this sequence.
(This means that the key first pressed is programmed as the 0 key, the
key pressed second as 1 key ---- and the last key pressed as the TL
key.)
To inhibit a particular key, press the 0 key at the point when that key
should be programmed.
2. PROGRAM RESETTING (INITIALIZATION)
Set the reset switch to OFF position and turn-on the machine.
And the reset switch move to ON position without any key pressing.
This resetting resumes the initial program without clearing memory.
