LOW VOLTS ADJUST - LED 5 (green) FLASHING
To avoid total discharging of your battery the WM1500 shuts down at a pre-set low voltage. As all
batteries are different, so too is the minimum voltage they should be discharged to. The WM1500 will
leave the factory with a setting of
22.0 Volts
, change this setting if required.
From Demand Start Adjust, page 6, hold the Mode button down, (approximately 1 second), until LED 5
is FLASHING, indicating you are ready to adjust this setting. Now press the Mode button until the
desired value is sought. LED’s 1 – 4 will return to Status Indication after 10 seconds if a key is not
pressed.
