7.3 BATTERY LEvEL INdICATOR
The Battery Level Indicator (BLI) indicates the status of the T7’s power system. Several modes are displayed through the BLI.
• Standby Mode: All of the T7’s BLI lights are dark.
• Charging Mode: The BLI is depicted with four bars representing increments of battery charge level. If the battery is
less than 25% charged, the lowest bar will be blinking. If the battery is less than 50% charged, the lowest bar will be
solid and the second bar will be blinking. If the battery is less than 75% charged, the lowest two bars will be solid and
the second to highest bar will be blinking. If the battery is less than 100% charged, the lower three bars will be solid and
the top bar will be blinking.
• Charging Finished Mode: When input power is removed from the cart by unplugging from the wall, all four lights
are illuminated.
• Discharge Mode: The BLI displays how much battery capacity is left. At full battery capacity, all lights are illuminated.
As power is drawn from the battery, the lights extinguish sequentially from top to bottom, counting down capacity in
approximately 25% increments. Once the cart reaches the 25% level, the bottom LED turns to yellow. Once the battery
level reaches the critically low battery level, the bottom LED turns red and an optional beeping sounds. This is an indication
that approximately one minute of run time remains and the system should be plugged in immediately to prevent loss of
operation and/or data.
