Black & Decker VEC054D Troubleshooting, Common Audio/Visual Problems, Resetting the Unit

TROUBLESHOOTING

Common Audio/Visual Problems

Problem	Solution
“Buzzing” sound in audio	Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from
systems	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 amplified supply.
Television Interference	The Inverter is shielded to minimize interference with TV signals. 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 the antenna feeding the television provides an adequate (“snow
		free”) signal and that high quality, shielded antenna cable is used.
	•	Do not use the inverter to operate high-power appliances or tools at the same
		time you are using it to operate the TV.
	•	Make sure the inverter’s case is properly grounded (refer to the “Permanent
		Installation Procedure” section of this Instruction Manual).

Resetting the Unit

After over-voltage or thermal automatic shutdown, the VEC054D will reset automatically. To reset all other units, turn the ON/OFF Power Switch to the “OFF” position, then back “ON.”

Trouble/Indication

Possible Cause

Suggested Remedy

No AC output —	DC input is below 10 volts	Recharge or replace battery.
red LED lit
	Excessive appliance load	Turn unit OFF. Reduce the load, wait for the
	— thermal shutdown	inverter to cool down, then turn the unit ON
		again.
No AC output —	Fuse(s) open	Check DC input — fuse(s) in vehicle. Replace
green LED not lit		the fuse with one of the same type and
		rating if necessary.
Low battery alarm	Low battery voltage	Recharge battery. Remove load from the
sounds continuously		inverter while recharging battery.
	Bad connection or wiring	Tighten all DC connections.
Motorized power tool	Excessive start-up load	If appliance does not start, appliance is
will not start		drawing excessive voltage and will not work
		with inverter.
Motorized power tool	Purely inductive load	Make the load not purely inductive. Operate
does not operate at		an incandescent lamp at the same time as
correct speed		motor.
Television/radio	Snow in picture,	Keep inverter and antenna distant from each
interference	“buzzing” sound	other. Use shielded antenna. Connect antenna
		to amplifier.
