LCD

 submenus. Descriptions of the letter codes are as follows:

• 

BV

 = Battery Voltage

• 

LOK

 = Battery Lock Level

• 

ACT

 = Deck Actuator Current

• 

SOL

 = Solution Solenoid Current

• 

BRU

 = Brush Motor Contactor Current

• 

VAC

 = Vacuum Motor Contactor Current

• 

DET

 = Detergent/Chemical Pump Current

The default setting is
