Protection Functions
If one or more of the causes of the following problems occur, the protective circuits will acti-
vate, and you will no longer be able to use the TOS5200. This is referred to as PROTECTION
mode.
When the TOS5200 switches to PROTECTION mode, “PROTECTION” on the screen lights.
Follow the instructions below to remove the cause of the problem and clear the PROTEC-
TION mode.
If the TOS5200 has switched to PROTECTION mode because of several causes, the cause
with the highest priority is displayed. After you eliminate the cause, the cause with the next
highest priority is displayed to indicate that there are more causes.
If you cannot clear the mode even by pressing STOP, turn the TOS5200 off and then back on.
If you cannot clear the PROTECTION mode even after you have corrected all the causes, the
TOS5200 may be malfunctioning.
Stop using the product, and contact your Kikusui agent or distributor..
