Description

Default

Parameters

Key auto repeat

25

Use this setting to select whether or not holding down a key causes 
repeated input of the key. For keys that normally cause a set value to 
increase when held down (for example, holding down the [ZOOM] 
key), this program can be used to have the set value not change 
when the key is held down.

0 (OFF)

1 (ON)

Key press time

26

Use this setting to select how long a key must be pressed for the 
input to be accepted. By selecting a longer time, you can prevent 
settings from being changed by the accidental pressing of a key.

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.

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.

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.
