3. INSPECT BATTERY VOLTAGE

(a) Measure the battery voltage.

Standard Voltage:

11 to 14 V

* If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.

NEXT -- Continue to next step.

4. CHECK CABIN

(a) Check that condensation is not likely to occur in the cabin, and that the temperature is not high or extremely low in the cabin.

OK:

Condensation is not likely being produced and the temperature is not high or extremely low.

HINT
* A humid cabin and a rapid change in temperature may lead to condensation. Condensation in the cabin may cause a short circuit.
* The audio and visual system may not operate normally when the temperature is -20°C (-4°F) or lower, or 65°C (149°F) or higher.

NG -- SET CABIN TO APPROPRIATE TEMPERATURE
OK -- Continue to next step.

5. PROBLEM SYMPTOMS TABLE

(a) Refer to Problem Symptoms Table Problem Symptoms Table.
