CAUTION 
Do not change the quantization level settings unless 
absolutely necessary.    If set at an inappropriate value, 
the acquisition or tracking function of the target tracking 
function (TT) deteriorates, and this may lead to accidents.
Make sure to shut off the main power before replacing 
parts.    Failure to comply may result in electrocution or 
equipment failure. 
When replacing magnetrons, make sure to shut off the 
main power and let the equipment stand for more than 5 
minutes to discharge the high-voltage circuit.    Failure to 
comply may result in electrocution. 
Make sure to take off your watch when your hand must 
get close to the magnetron. 
Failure to comply may result in damage to the watch 
since the magnetron is a strong magnet. 
Make sure that two or more staff member work together 
when replacing the LCD.    If only one person attempts to 
replace the LCD, he/she may drop it and become injured. 
Do not directly touch the inverter circuit of the LCD 
display with a bare hand since high voltage temporarily 
remains in the circuit even after the main power is shut 
off. 
Failure to comply may result in electrocution. 
Any adjustments must be made by specialized service 
personnel. 
Failure to comply may result in accidents or equipment 
failure.
