DIGITAL TEMPERATURE CONTROLLER
INSTRUCTION MANUAL
Before using this product, please carefully read this manual for its correct use. In addition, after reading the manual,
keep it available easily anytime.
OPERATION PRECAUTIONS
Before cleaning the instrument, check that the power is turned off.
Please using the soft clothes or tissue paper to remove stains on the display unit.
Because the display unit is easily scratched, please do not scrub or touch it with a hard object.
Do not operate the front key with a pointed object such as a ballpoint pen or screwdriver, as this may scratch or
damage the key.
