Lead Free Solder
Among some types of lead free solder currently available, it
is recommended to use one of the following types for the
repair work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
1. As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than that of the lead
solder, be sure to use a soldering iron suitable to each solder.
2. If lead solder must be used, be sure to remove lead free solder from each terminal section of the parts to be replaced and from
the area around it completely before soldering, or make sure that the lead free solder and lead solder melt together fully.

The protection function worked due to a DC voltage appearing at the speaker terminal.
A cause could be a defect in the amplifier. If the power is
turned on with the abnormality unsolved, the protection function works in about 3 seconds to turn off the power.
● Operation procedure of DIAG MENU and
SUB-MENU
There are 8 MENU items, each of which has some SUBMENU items.
DIAG menu selection
Select the menu using PRESET NO keys.
DC PRT :000 Z
The protection function worked due to the temperature limit
being exceeded. Causes could be poor ventillation or a defect related to the thermal sensor. The abnormal voltage is
displayed in % based on 5V as 500%. If the power is turned
on with the abnormality unsolved, the protection function
works in about 1 second to turn off the power.
SUB-MENU selection
Select the sub-menu using w (Forward) and q (Reverse)
keys of TUNING.
TMR PRT:000 Z
For detection of each protection function (except I-PROTECT) , refer to DIAG MENU No.3 AD DATA CHECK (p.13).
● History of protection function
When the protection function has worked, its history is stored
in memory with a backup. Even if no abnormality is noted while
servicing the unit, an abnormality which has occurred previously can be defined as long as the backup data has been
stored.
The history of the protection function is cleared when DIAG is
cancelled by selecting PRESET RESERVED (Memory initialized) of DIAG menu No.2 or when the backup data is erased.

With this sub-menu used, the key scanning, A/D value of
the voltage at the abnormality detect (protection) port, etc.
are displayed. The A/D conversion value is displayed in %.
The state before audio signal processing is kept.
When K0/K1 menu is selected, keys become nonoperable
due to detection of the values of all keys.
However, it is possible to advance to the next sub-menu by
turning the INPUT of the main unit. When using this function, note that turning the INPUT more than 2 clicks will
cause the volume value to change.

8. MICROPROCESSOR INFORMATION
Note) Changing the function setting may hinder the proper
operation.
This menu is used to switch the function settings on P.C.B.
through the software so as to activate the product.
The operation mode can be changed by selecting the submenu and then using the EDIT key.
The protection function follows the P.C.B. settings.
When connected to AC, the unit is initialized to the P.C.B.
setting. Display of each function after initialization varies
depending on settings on P.C.B.
The version, checksum and the port specified by the
microprocessor are displayed. The checksum is obtained
by adding the data at every 16 bits for each program
area and expressing the result as a 4-figure hexadecimal
data.
