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
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.
CAUTIONS
THERE IS A RISK OF EXPLOSION IF THE BATTERY
IS REPLACED BY AN INCORRECT TYPE.
PROPERLY DISPOSE OF USED BATTERIES ACCORDING
TO THE INSTRUCTIONS.

If the user forgets to replace the battery and the battery voltage falls
below a certain level, or if a power failure occurs with no batteries
installed, the memory contents cannot be retained. The CPU judges it
as no battery and performs the master reset. In this case, all the settings and registrations are cleared. If, however, the power is continuously supplied to the AC cord, the memory contents are retained.

CHAPTER 3. MASTER RESET
Master reset:
Clears all the memory and initializes each preset parameter.
The master reset should be performed by using the following procedure.
1. Turn off the power (Power OFF). (See Note 1.)
2. Remove the memory back up battery from ECR.
3. Turn the mode switch to any position other than Power OFF.
4. Turn on the power (Power ON). (See Note 2.)
When the master rest is completed, the buzzer sounds three times.
5. Install the memory back up batteries back into the ECR.
The master reset can also be accomplished in the following case.
(See Note 3.)
Note 1) Power OFF:
Means disconnecting the AC power supply to the
machine. (Specifically, unplugging the machine.)
Note 2) Power ON:
Means connecting the AC power to the machine. (Specifically, plugging in the machine.)
Note 3) In case a power failure occurs when the machine has no
battery installed, the master reset operation is automatically performed after the power has been restored.
