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.
CAUTIONS
n
Risk of explosion if battery is replaced by an incorrect type.
Dispose of batteries according to the instructions.
n
Do not leave the unit with the battery discharged for more than one month. 
It will shorten the battery life. 
If the unit is left unused for a long period, be sure to charge the battery fully. 
Also note that the battery must be charged periodically (once a month) because it will discharge naturally.

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.
