POWER SWITCHES: There are two round, momentary push button switches used to turn the
unit on and off. The GREEN "ON" push button switch is used to turn the unit on. The RED "OFF"
push button is used to turn the unit off. Please note that the RED "OFF" push button switch is
equipped with a time delay circuit. You must press and hold this push button switch for 3-4
seconds before the unit will shut off. This time delay function serves to keep you from
accidentally shutting down the PSC Baby Zeus unexpectedly while working.

FUEL GAUGE: The PSC Baby Zeus is equipped with an easy to read and easy to understand multi-
colored battery "Fuel Gauge". Just a quick glance and you will immediately know the charge
condition of your battery. A full row of Green LEDs indicates a fully charged battery. As the
battery is discharged, the LEDs slowly go out. It is similar to reading the fuel gauge in your car.
When the last (left most) RED LED goes out, the unit will shut down to protect the LiFE batteries
from deep discharge. The unit must then be plugged into AC power to re-charge the batteries
and/or power up your equipment. Both charging and use can be done simultaneously.
