■ 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.

(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 rec­ommendable.
(2) NOTE FOR SOLDERING WORK
Solder composition code
a
b
z

n
s
p
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 tem­perature 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 com­pletion 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.

9. BATTERY
1) MEMORY BACK UP BATTERY
For memory back up, the dry battery AA (3 pieces) are needed.
1. Memory holding time:
Approximate 1 year after New dry batteries are inserted.
2. Battery exchange method:
When the low battery symbol “L” lights up, batteries (3 pieces) exhange by the following method, with 2 days.
1) Power on the ECR.
2) Mode switch turn to “REG” mode.
3) Release the OLD dry batteries (3 pieces).
4) Insert the NEW dry batteries (3 pieces).
5) Confirm the low battery symbol “L” lights off.
2) LOW BATTERY
Low battery indication will appear on the left side of display when the battery voltage is low.
CASE 1: When any numeric entry & any item entry is not done or just
after finalization.
The machine can indicate the low battery condition. (Always)
CASE 2: When numeric entry or item entry is done.
Battery condition will not appear. Exceptionally, when the power is restored after a power failure, the low battery condition will appear on the display only when the bat­tery is low. And the indicator will disappear after any key entry.

CHAPTER 3. MASTER RESET AND PROGRAM RESET
1. MASTER RESETTING
Master resetting clears the entire memory and resumes initial values.
Master resetting can be accomplished by using the following procedure:
Procedure A: 1) Unplug the AC cord from the wall outlet or set the
mode switch to OFF Position.
2) Let the ECR be without the memory back up battery.
3) Wait over 1 muinite for discharging.
4) Set the mode switch to any position except OFF.
5) Plugin the AC cord to the wall outlet or turn the mode switch from OFF Position to another position.
The master reset can also be accomplished in the following case.
In case power failure occurs when the machine has no battery attached to it, the master reset operation is automatically performed after the power has been restored. (This is because if power failure occurs with no battery attached to the machine, all the memories are lost and the machine does not work properly after power recovery; this requires the master reset operation.)
2. PROGRAM RESETTING (INITIALIZATION)
This resetting resumes the initial program without clearing memory.
This resetting can be operated at below sequence in PGM mode.
Procedure: 1) Unplug the AC cord from the wall outlet.
2) Wait over 1 muinite for discharging.
3) Set the mode switch to the PGM position.
4) While holding down the FEED key, plugin the AC cord to the wall outlet.
Note: In case power failure occurs when the machine has no battery
attached to it, the master reset operation is automatically performed after the power has been restored.
