LoW inPUt VoLtAGe ALARM
An alarm will sound when the DC input
voltage from the battery drops to 10.5
volts. This is an indication that the battery
needs to be recharged. The user should
stop operation of the electronic device at
this time since the inverter will shut down
shortly thereafter, when the battery volt-
age drops to 10 volts. Start your engine to
recharge the battery. Status of LEDs and
buzzer:
red LED “fAULT” (3) .................................off
Green LED “Power” (4) ...............................oN
Yellow LED “Input fault” (5) .....................off
buzzer ...........................................................oN
reset ............................................... Auto- reset
If the low DC input voltage alarm sounds
when the battery is fully charged, follow
the steps for solving lack of output power
in the Troubleshooting guide. The alarm
will sound when the inverter is over-
loaded, in thermal shutdown, or if there
is an excessive voltage drop between the
battery and inverter.
note: It is normal for the alarm to sound while
the unit is being connected to, or disconnected
from, the power source. This is not indicative of
a problem.

read the information panel on each pow-
er tool carefully to accurately determine
the tool’s input wattage. Please remember
that the power needed to start the power
tool may be as much as 2 to 6 times its
continuous wattage requirements.
“BUZZinG” SoUnD in
AUDio SYSteMS
Some inexpensive stereo systems and
“boom boxes” emit a buzzing sound from
their speakers when operated from the
power inverter. This occurs because the
power supply in the electronic device does
not adequately filter the modified sine
wave produced by the inverter. The only
solution to this problem is to use a higher
quality sound system that incorporates a
higher quality power amplifier supply.
teLeViSion inteRFeRence
The inverter is shielded to minimize inter-
ference with TV signals. The problem may
not be with the inverter. However, in some
instances, some interference may still be
visible, particularly with weak TV signals.
Try the following corrective measures:
- Position the inverter as far as possible
from the television, the antenna and
the antenna cables. Use an extension
cable, if necessary.
- Adjust the orientation of the inverter,
the antenna cables and the TV power
cord to minimize interference.
- Make sure that the antenna feeding
the television provides an adequate
(“snow free”) signal and that high
quality, shielded antenna cable is used.
- Do not operate high-power appliances
or tools when you are watching TV.
the advanced technology of SAMLeX, L.i.t greatly reduces the
possibility of interference with tV signals and audios.
