	the unit up on a ship or other place where DC is used.

	AC mains lead protection
	Ensure the AC mains lead is connected correctly and not damaged. Poor
	connection and lead damage can cause fire or electric shock. Do not pull,
	bend, or place heavy items on the lead.
	Grasp the plug firmly when unplugging the lead. Pulling the AC mains
	lead can cause electric shock.
	Do not handle the plug with wet hands. This can cause electric shock.

	Foreign matter
	Do not let metal objects fall inside the unit. This can cause electric shock
	or malfunction.
	Do not let liquids get into the unit. This can cause electric shock or mal-
	function. If this occurs, immediately disconnect the unit from the power sup-
	ply and contact your dealer.
	Do not spray insecticides onto or into the unit. They contain flammable
	gases which can ignite if sprayed into the unit.

	Service
	Do not attempt to repair this unit by yourself. If sound is interrupted, indi-
	cators fail to light, smoke appears, or any other problem that is not covered
	in these instructions occurs, disconnect the AC mains lead and contact
	your dealer or an authorized service center. Electric shock or damage to
	the unit can occur if the unit is repaired, disassembled or reconstructed by
	unqualified persons.
	Extend operating life by disconnecting the unit from the power source if it
	is not to be used for a long time.
