Balance Control Port Hole Location
There are 4 holes strategically placed on the front of the control panel, between the green display and the red
displays. These holes are used to access and adjust the balance variables. Use an appropriate sized tool or
paper clip to access balance keys through the port holes in the control panel. Reference the sketch of the
control panel for location/identification of balance control port holes which will need to be accessed to perform
balance time/date setting, balance resetting, and balance calibration procedures.
