AUXILIARY MECHANISM: TEMPERATURE SETTING TRIMMER
The trimmer compensates for differences in range of ±3°C (±6°F) between temperature setting (temperature
control dial position) and temperature felt by customer.
Operating procedures for this trimmer are as follows:
1. Set fan control dial to OFF.
2. Turn ignition switch ON.
3. Set in self-diagnosis mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press intake switch for at least 5 seconds.
4. When intake switch is pressed, temperature shifts in following order: 0°C (0°F)→ 1°C (2°F)→ 2°C (4°F)→
3°C (6°F)→ −3°C (−6°F)→ −2°C (−4°F)→ −1°C (−2°F)→ return to 0°C (0°F).
When battery cable is disconnected or battery voltage is below 9 V, trimmer operation is canceled. Tempera-
ture set becomes that of initial condition, i.e. 0°C (0°F).

AUXILIARY MECHANISM: FOOT POSITION SETTING TRIMMER
Wind distribution ratio in FOOT mode can be set.
Operating procedures for this trimmer are as follows:
1. Set fan control dial to AUTO.
2. Turn ignition switch ON.
3. Set in self-diagnosis mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press intake switch for at least 5 seconds.
4. Press intake switch as desired.
When battery cable is disconnected or battery voltage is below 9 V, trimmer operation is canceled. Wind distri-
bution ratio set becomes that of initial condition.
AUXILIARY MECHANISM: INLET PORT MEMORY FUNCTION
When ignition switch is turned from OFF to ON, inlet port memory function at manual mode can be set.
Operating procedures for this trimmer are as follows:
1. Set fan control dial to 1st - 12th speed.
2. Turn ignition switch ON.
3. Set in self-diagnosis mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press intake switch for at least 5 seconds.
4. Press intake switch as desired.
