D. CHARGE INDICATOR LIGHT
A green LED which will illuminate when external power has been applied and the unit has been placed in the battery
charging mode of operation.
E. BATTERY STATUS ENABLING SWITCH
Activates the Battery Status Indicator by toggling up or down and holding.
F. BATTERY STATUS INDICATOR
Illuminates in three different modes to indicate battery potential.
Continuous green = battery is fully charged
Pulsing green = battery is partially discharged, 50% or less capacity remaining
Red = battery is fully discharged, recharge immediately
G. CHARGE INTERLOCK INDICATOR
Illuminates when the ambient temperature within the housing is too high to charge the battery safely. When illumi-
nated, the charging circuit has been disabled. The system can be run but cannot be charged.
H. PUMP ROTATIONAL DIRECTION SELECTION AND ON/OFF SWITCH
This switch turns the pump ON and OFF and allows user to select pump rotational direction: CW or CCW. The center
position is off.
I. SPEED CONTROL
The one (1) turn potentiometer controls the pump speed. CW increases the speed, CCW decreases it.
J. MAX
A switch which bypasses the speed control circuitry to make the pump run at its maximum rated speed. Can be used
to prime or purge tubing depending on the position of the Rotational Direction Selection Switch (H).
K. DRIVE POWER INDICATOR
A green LED which illuminates when the Rotational Direction Selection (ON/OFF) Switch is in a position other than
off. This indicates that the drive mechanism is powered.

1. Select Mode of Operation

The unit can be operated in three different modes:
A. Charge the internal battery, this disables all other functions.
B. Operate the drive on the internal battery power source.
C. Operate the drive on an external power source.

2. Operation Directions

To Charge the Internal Battery with AC/DC Power Supply/Converter or other External Power Source:
CAUTION: Fully charge the unit before using for the first time. Damage to the internal battery can result if the
battery is in a fully discharged state and operation of the unit is attempted.
A. Connect the supplied AC/DC Power Supply/Converter to drive by lifting EXTERNAL POWER INPUT (A)
receptacle cover and inserting the 2.5 mm coaxial power jack into the receptacle. (See Figure 1.)
DANGER: NEVER apply AC voltages directly to the EXTERNAL POWER INPUT receptacle on the front panel.
The application of AC voltages can result in injury and death of the operator and destruction of the
unit. Use only the AC/DC Power Supply/Converter supplied with the unit to power unit from an AC
source.
B. Connect AC/DC Power Supply/Converter to an AC power source. Place the Power Source Selection
Switch (B), (EXTERNAL/BATTERY) in the "BATTERY" position.
C. Place the Mode of Operation Selection Switch (C), (RUN/CHARGE) to the "CHARGE" position.
D. The CHARGE indicator will illuminate.
E. Charge the battery for 8–12 hours.
