RA3800 Operation
Initial Charge
Before using the jump start for the first time, charge the unit for 24 hours, or until the MAC02 Battery
Charger supplied with the equipment indicates fully charged.
Testing RA3800 Charge Status
Test 12VDC Status - Switch to 12V position then press and hold TEST switch. VOLT METER indicates
status
Test 24VDC Status - Switch to 24V position then press and hold TEST switch. VOLT METER indicates

Operation
1.
Turn the ignition off before making connections
2.
Ensure the RA3800 voltage selector is in the OFF position
3.
Attach the red / positive
+
clamp to the battery positive terminal
4.
Attach the black / negative
-
clamp to the battery negative terminal
5.
The RA3800 voltmeter displays the voltage of the battery being started. If less than 3 volts on 12 volt
setting, or 6 volts on 24 volt setting - do not attempt to jump start the vehicle. The battery voltage is
too low - an attempted jump start would be dangerous. Replace the battery.
6.
If displayed voltage is above 3 volts on 12 volt setting, or 6 volts on 24 - select either 12V or 24V
7.
Keep cables clear of moving objects
8.
Keep people clear of the battery area
9.
Turn vehicle ignition on.
If vehicle does not start after 6 seconds,
allow the RA3800 to cool for 3
minutes before attempting to restart the vehicle. This avoids damage to the unit.
10.
Once started, disconnect the black / negative
-
clamp from the battery negative terminal. Then remove
the red / positive
+
clamp.
•
Risk of Short Circuit.
•
The REVERSE polarity led and buzzer only provides an indication of a short circuit
if the RA3800 is switched OFF.
Leave the RA3800 on charge when not in use - the MAC02 is a Charger / Maintainer
and will maintain the batteries in peak condition longer.
Turn the switch to the 12V
position for charging. In the OFF position - only 1 of the 2 batteries are charged
