2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
● Meter impedance should be equivalent to 1500 ohms

WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and
possibly other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.

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.

Start the DIAG function of the main unit and check that
the checksum value (F : After boot area) is the same.
* If there is a difference, perform the procedure again
* If writing is not successful or the power cannot be
turned on after writing, it is possible to enter the
updating mode by using "FORCED BOOT MODE" and
execute writing again.
Preparation
• Perform Steps a to d of MAIN writing procedure.
• Remove the "VOLUME" knob from the front panel of the
main unit.
• Connect the power plug to the AC outlet.
• Prepare a flatblade screwdriver.
1. While pressing the "MULTI CH INPUT" key of the main
unit, press the "RESET SWITCH" key using a flatblade
screwdriver.
2. Immediately after releasing above two keys ("MULTI
CH INPUT" key and "RESET SWITCH" key), press and
hold the "MULTI CH INPUT" key until "232C BOOT
xxxx" is displayed.
If the display remains unchanged from "Upgrader xxxx",
start all over from Step 1.
When "232C BOOT xxxx" is displayed, go to Step h of
MAIN writing procedure and continue the procedure.
