Digital Battery Meter
The digital display will show the external battery voltage when the power pack is connected.
If the polarity is incorrect on the battery connection, there will be no display. Pressing the
internal battery voltage button will display the internal voltage expressed either as 12V or
24V depending on the switch setting on the back of the power pack. When the power pack
is being recharged, the meter will show charging with the letters CH and animation speed
depending on the amount of current flow. When the unit is fully charged, the display will
read FUL.
LED Indicator Lights
The yellow Low Voltage LED indicator light will illuminate whenever the Rescue 2100 is
turned on and the external voltage at the clamps is low, or they are not connected. This is
normal. See the section on using the Rescue 2100 as a 12V or 24V power source.
The voltage indicating LED lights will indicate internal low battery voltage by flashing. The
more discharged the internal battery becomes, the faster the light will flash. Press the inter-
nal battery voltage button to see the exact internal battery status.
12V Auxiliary Power Outlet
The 12V auxiliary outlet is protected by a 15 amp circuit breaker, which resets automatically.
Troubleshooting
Problem: Rescue 2100 turns off under load.
• The internal battery may be low.
• Check the internal battery voltage and recharge as needed.
• Extremely high current draw is present. This may be because there is a short circuit
in the system to be jump started.
• Check the system for short circuits.
• The load required may exceed the capacity of the Rescue 2100. Very large batteries or
battery banks may require recharging, not jump start assistance.
Problem: Green power light fails to light when the start button is pressed.
Unit is sounding a tone.
• Check the reverse polarity light. If it is illuminated, reverse the clamp connections.
• Check the voltage error light. If it is illuminated, select the correct battery voltage.
• The internal battery voltage is below 8.5V. Check the internal battery voltage, and
recharge the unit.
Problem: The Rescue 2100 will not recharge.
• If no tone is sounding, check the power cord for secure connection, and verify that the
wall power outlet is live.
• If tone is sounding, turn the voltage selector to 12V.
Problem: The low voltage light is lit and the unit will not engage.
• This can happen if the battery on the unit to be started is severely discharged.
1. Verify that the proper voltage has been selected on the Rescue 2100.
2. Verify that the clamps are connected correctly, positive to positive and negative
to ground.
3. Press and hold the Start button for 4 seconds.
4. Verify the green Power light is on. The unit is now connected.
