To change the Battery Discharge Profile V+ must be 
connected to the set up pin (2). After V+ is applied to 
pin 2 press and hold the left button until the time of day 
clock flashes the 4 clock digits. If no change in clock 
setting is desired use the left button to progress to the 
discharge profile 
Configuring Your Gauge 
Access to these operations is sequential in this order. 
Adjustments of the following functions can be 
performed in the Configuration Mode: 
 
1. Time-of-Day Clock 
2. Battery Discharge Indicator Profiles 
 
During configuration, the right button is used to 
increment. The left button is used to: 
 
1. Enter a selection 
2. Advance to the next configurable item 
 
If no change is desired to a specific gauge function, 
continue to press the left button until the next desired 
function is reached. The time-of-day clock is entered 
by setting the hours digits between 01 and 12, then 
"minutes" digits between "00" and "59". 
 
 The profile of the BDI is settable with the front panel 
buttons. 
 
Setting the Battery Indicator 
Profiles 
 
The display flashes the 3 digits of the discharge full 
profile. Press the right button to increment by 0.10 
VPC or hold the button to increment continuously. 
When the display reaches 2.30 it will automatically 
restart at 1.80 VPC. When the desired reset profile 
setting is reached, press the left button once. 
 
The display flashes the 3 digits of the discharge empty 
profile. Press the right button to increment by 0.10 
VPC or hold the button to increment continuously. 
When the display reaches 2.20 it will automatically 
restart at 1.50 VPC. When the desired reset profile 
setting is reached, press the left button once. 
 Setting the Time-of-Day Clock 
 
The display will flash the two "Hours" digits. Press the 
right button to increment by one hour, or hold the 
button to increment continuously. When the desired 
number of hours is reached, press the left button once. 
The display will flash the two "Minutes" digits. Press 
the right button to increment by one minute or hold the 
button to increment continuously. When the desired 
number of minutes is reached, press the left button 
once. 
 
The gauge remains in configuration mode for 30 
seconds without input from the user. When configuring 
each function (time-of-day, BDI Profile), you must 
enter in all data for that function for it to be saved. If 
incomplete data is entered for a function and the 
programming mode is timed out (after 30 seconds of 
no input received by the gauge), the gauge will revert 
back to what was previously stored for that item.

 Operation 
 
When the main power (9-60 VDC) is applied to V+ and 
V-, a power-up sequence is initiated. All display 
segments are illuminated for one second. The display 
is then turned off until the key switch is activated.
