I know, my friend was there. I remember him talking how he stucked there for almost half an hour. LOL. I can't even imagine that, but I would like to see it 🙂
Well, try this one:
All right, here's the explaination:
1: 大 (big) causes to a large flush for soilds.
2: 小 (small) causes a small flush for liquids.
3: Lowers the lid and closes the seat
4: Lowers the seat and raises the lid
5: Raises both the lid and the seat
6: Stops all operations (7-12 only)
7: おしり(Bottoms): Regular bottom wash
8: やわらか (Tender): Gentle bottom Wash (useless, I recommend 7 instead)
9: ビデ: (Bidet): Female-use wash.
10: 乾燥 (dry): Dry your bottom
11: ムーブ (入/切)(Move): Rotates the nozzle sideways back and forth
12: マッサージ (入/切) (Massage): Massage of the bottoms by water spray.
13: Hour adjustment button
14: Minute adjustment button (13 and 14 sets the time of the day)
15: Set (confirm adjustment of time)
16: Increase seat temperature
17: Decrease seat temperature
18: Increase strength of the air to dry your bottom (see button 10)
19: Decrease strength of the air to dry your bottom (see button 10)
20: Increase water temperature of water spray
21: Decrease water temperature of spray
22: Increase room temperature
23: Decrease room temperature
24: Increase strength of the water spray
25: Decrease strength of the water spray
26: Toilet bowl CLEANS ITSELF!
😱 (start/stop this - press once to start, press again to stop)
27: Water Spray Nozzle ALSO CLEANS ITSELF (same as 26)
28: Enable/Disable sensor for cleaning (as in, toilet washes itself after every use)
29: Enable/Disable sensor for "flow" (air flow in the toilet, in other words, to purify the air after use - remember, the WHOLE toilet unit comes as one set, including air flow unit and lights - but not the sink...)
30: Enable/Disable sensor for music to play during use of toilet
31: Random electricity saving (in other words, goes into energy-saving mode when not used for a period of time)
32: Timed electricity saving (goes into energy-saving at a preset timeslot)
33: Adjust forwards nozzle position
34: Adjust backwards nozzle position
35: Start/Stop automatic air refreshener spray
36: Enable/Disable toilet cubicle air conditioning (not the same as ventilation)
37: Enable/Disable Antifreeze function
38: Set timer for toilet cubicle air conditioning
This is the most advanced, and the most popular model on highway rest stops, especially in handicapped toilets.
Non-handicapped toilets would then fall into two categories: Nearer the city and further away.
Nearer the city areas, you'll find this common:
Stop (止): Stops all operations
Bottom (おしり): Washing of the bottom
Gentle (やわらが): Gentle washing of the bottom
Move On/Off (ムーブ (入/切)): Rotates the nozzle sideways back and forth.
Massage On/Off (マッサージ (入/切)): Cyclic increase in the nozzle pressure for a masage of the bottom.
Bidet (ビデ): Female-use wash.
Move On/Off (ムーブ (入/切)) Move: Rotates the nozzle sideways back and forth.
Dry (乾燥: kansou): Blow dryer for drying the bottom
Water strength (水勢): Increase the water pressure with the top button (強) and decrease the pressure with the bottom button (弱)
Nozzle (ノズル: nozuru): Move the nozzle slightly forward with the top button (前) and backward with the bottom button (後)
And the ones further away:
That's all folks!
