This warning occurs when the battery charge is calculated as This warning occurs when the battery charge is calculated as being less or equal to being less or equal to 10% of a10% of a
full charge and the full charge and the BATTERY CHECK parameter is set to a value other than BATTERY CHECK parameter is set to a value other than 0 (located in the0 (located in the
SET OPTION menu).SET OPTION menu).
In such a case, charge the battery. If it does not help, measure the battery voltage with aIn such a case, charge the battery. If it does not help, measure the battery voltage with a
voltmeter and compare it with the value voltmeter and compare it with the value of the BATTERY VOLTAGE parameter. If they areof the BATTERY VOLTAGE parameter. If they are
different, adjust the value of different, adjust the value of the ADJUST BATTERY parameter.the ADJUST BATTERY parameter.
When adjusting the battery voltage, voltage should bWhen adjusting the battery voltage, voltage should be measured from the key line, after e measured from the key line, after thethe
