5.12. Checking the Heater
Check if the Heater increases its temperature properly by the list of the room temperature and its time till it reaches designated tem-
peratures.
(Our criterion is that the spot touching the human body is 50 °C (122°F). However, there is the balance 5 °C (41°F) in the Heat sen-
sor and the spot of the human body touching the Massage ball, therefore in the list 45 °C (113°F) is used as criterion.)
Caution:
• Carry out the checking with nobody sitting or without operation of the Massage mechanism block.
• Heater massage balls need to be cool enough (normal temperature).
• The balance between right/left Massage balls is within ±5 °C (41°F). If the values are within this range, it is not faulty.
Checking procedures
1. Start CE mode of the Secret Mode of the Controller.
2. If you push the REPEAT button for several times,,,,,,,,
For example,
<CE>

Once <02>

Twice <05>

Thrice <2>

Fourth <4>
This means that one of Heal balls is 25 °C (77°F) and the other is 24 °C (75°F). If you push OK, it resumes to the beginning.
* You can know the original temperatures of the Massage balls.
3. Push the button of Massage block heater OFF/ON and turn on the switch, and measure the time of the increase of the tem-
perature.
4. Repeat the procedures of 2. and measure the time till 45 °C (113°F) is shown.
5. Check the Massage block heater by the list. For example, if the room temperature is 20 °C (68°F) and 45 °C (113°F) is shown
within 150 seconds, it can be judged “Good”.
