Notes on chip component replacement
Never reuse a disconnected chip component.
Q
Q
Notice that the minus side of a tantalum capacitor may be
damaged by heat.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
TEL 13942296513 QQ 376315150 892498299
Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 °C. Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

VERSION MODE
When this mode is used, the model, the destination and the software version number are displayed.
Procedure:
KEY CHECK MODE
This mode is used to check the key.
Procedure:
STR-KS500
1. While pressing the [SOUND FIELD +] and [PRESET TUNING --] buttons, press the I/1 button to turn on the main power.
2. The model, the destination and the software version number appear.
1. While pressing the [MUTING] and [INPUT SELECTOR] buttons, press the I/1 button to turn on the main power.
2. The message “REST 06” appears.
3. Every pressing of any button other than the I/1 button counts down the buttons. The b uttons which are already counted once are not counted again.
4. When all buttons are pressed, the message “REST 00” appears.
