NOTICE CONCERNING FCC REGULATIONS

This equipment generates and uses radio frequency energy and may cause interference to radio and
television reception if you do not operate it in strict accordance with the procedures detailed in this
OPERATING MANUAL.
This unit complies with Class B computing device rules in accordance with the specifications in
Sub-part J or Part 15 of the FCC Rules, which are designed to provide reasonable protection against
such interference in a residential installation. There is no guarantee, however, that interference will
not occur in a particular installation. If the unit does cause interference to any radio or television
reception, try to reduce it by one or more of the following means:

a) Reposition the other unit and/or its antennae
b) Move this unit
c) Move this unit and the other unit(s) further apart
d) Plug this unit into a different AC outlet so that it is on a different circuit from the other
equipment.

This note is in accordance with Section 15.838 of the FCC Rules.

This unit does not exceed the Class B limits for radio noise emission from digital apparatus set out
in the radio interference regulations of the Canadian Department of Communications.

For 220-volt use in USA, use NEMA style 220-volt plug. For other countries

use proper plug for local outlet.

DOUBLE INSULATED - When servicing use only identical replacement parts

VERY IMPORTANT

Please read this section before connecting these monitors to your

For optimum performance:

• Always make sure that AC power is OFF while making any connections.

• Never use spray cleaners on the control knobs. Residues cause excessive

dirt build-up and this will void your warranty. In normal use, control knobs

can last for many years. If they malfunction (usually because of a dirty or

dusty environment) consult a professional technician.

• Use appropriate cables throughout your system. Do not use excessively

long cables (i.e. over 50ft/14m) Be sure plugs and jacks are tightly mated.

Loose connections can cause hum, noise or intermittents that could easily

damage your speakers. Make the input and output connections with readily

available low-capacitance stereo cables. Quality cable makes a big

difference in audio fidelity and punch. See your ION dealer or an

electronics or audio specialist store if you are not sure which cables to use.

• Never attempt to make any adjustments other than those described in this

manual, or repairs. Take the unit to your dealer or to an authorized ION

Service Center.

• Always remember: “TURN AMPS ON LAST AND OFF FIRST”. Begin with

master faders or volume controls on minimum and the amplifier gain/input

control(s) down. Wait 8 to 10 seconds before turning up the volume. This

prevents transients which may cause severe speaker damage.

• Use restraint when operating controls. Try to move them slowly. Rapid

adjustments could damage equipment due to amplifier clipping.

• Avoid amplifier “clipping” at all costs: this occurs when the red LEDs

(usually on the front panel of most professional power amplifiers) start

flashing. “Clipping” is when the power amplifier is distorting and working

beyond it's limits. Amplifier distortion is THE major cause of speaker

failure.

• To prevent fire or shock hazard, do not expose the unit to rain or moisture.

Never place cans of beer, soda, glasses of water or anything wet near or

on top of the unit!
