NOTE: Indicator LED will not illuminate in this position.
NOTE:
• The audible alarm may make a momentary "chirp" when the
inverter is turned OFF (O). The same alarm may also sound
when the inverter is being connected to or disconnected from
the 12 volt power source.
• The use of an extension cord from the inverter to the appliance
or equipment being operated will decrease the power being
delivered to the load. For best operating results, the extension
cord should be no more than 50 feet long.
• Check frequently to ensure that the input and output
connections are secure. Loose connections may damage the inverter,
the power source, or may generate excessive heat.
Important Information on Battery Chargers
Using your inverter with battery chargers for power tools, flashlights,
video cameras and laptop computers may cause damage to the
inverter or the charging unit. Check with the appliance manufacturer
for compatibility with modified sine wave inverters if you're unsure.
Although we advise against it, if you attempt to use a charging
unit, monitor the temperature of the charging unit for
approximately 10 minutes. If the charging unit becomes
unusually warm, disconnect it from the inverter immediately.
