The meanings of these symbols are as follows:

This  symbol  indicates  explanations  about

incorrectly,  serious  injury  or  death  could
result.

This  symbol  indicates  explanations  about
dangerous  matters.  If  users  ignore  this
symbol and handle the device incorrectly,
bodily  injury  and  damage  to  the  equip-
ment could result.

Please observe the following safety tips and precau-
tions to ensure hazard-free use of the G1u.

Power requirements

Since power consumption of this unit is fairly high,
we recommend the use of an AC adapter whenever
possible. When powering the unit from batteries, use
only alkaline types.

[AC adapter operation]

• Be sure to use only an AC adapter which supplies 9

V DC, 300 mA and is equipped with a "center

minus" plug (Zoom AD-0006). The use of an

adapter other than the specified type may damage

the unit and pose a safety hazard.

• Connect the AC adapter only to an AC outlet that

supplies the rated voltage required by the adapter.

• When disconnecting the AC adapter from the AC

outlet, always grasp the adapter itself and do not

pull at the cable.

• During lightning or when not using the unit for an

extended period, disconnect the AC adapter from

the AC outlet.

[Battery operation]

• Use four conventional IEC R6 (size AA) batteries

(alkaline).

• The G1u cannot be used for recharging.

• Pay close attention to the labelling of the battery to

make sure you choose the correct type.

• When not using the unit for an extended period,

remove the batteries from the unit.

• If battery leakage has occurred, wipe the battery

compartment and the battery terminals carefully to

remove all remnants of battery fluid.

• While using the unit, the battery compartment

cover should be closed.

Environment

To prevent the risk of fire, electric shock or malfunc-
tion, avoid using your G1u in environments where it
will be exposed to:

• Extreme temperatures

• Heat sources such as radiators or stoves

• High humidity or moisture

• Excessive dust or sand

• Excessive vibration or shock

Handling

• Never place objects filled with liquids, such as

vases, on the G1u since this can cause electric

shock.

• Do not place naked flame sources, such as lighted

candles, on the G1u since this can cause fire.

• The G1u is a precision instrument. Do not exert

undue pressure on the keys and other controls. Also

take care not to drop the unit, and do not subject it

to shock or excessive pressure.

• Take care that no foreign objects (coins or pins

etc.) or liquids can enter the unit.

Connecting cables and input and output jacks

You should always turn off the power to the G1u and
all other equipment before connecting or disconnect-
ing any cables. Also make sure to disconnect all con-
nection cables and the power cord before moving the
G1u.

Alterations

Never open the case of the G1u or attempt to modify
the product in any way since this can result in dam-
age to the unit.

Volume

Do not use the G1u at a loud volume for a long time
since this can cause hearing impairment.

Usage Precautions

Electrical interference

For safety considerations, the G1u has been designed to pro-
vide  maximum  protection  against  the  emission  of  electro-
magnetic  radiation  from  inside  the  device,  and  protection
from external interference. However, equipment that is very
susceptible  to  interference  or  that  emits  powerful  electro-
magnetic  waves  should  not  be  placed  near  the  G1u,  as  the
possibility of interference cannot be ruled out entirely.

With  any  type  of  digital  control  device,  the  G1u  included,
electromagnetic  interference  can  cause  malfunctioning  and
can  corrupt  or  destroy  data.  Care  should  be  taken  to  mini-
mize the risk of damage.

Cleaning

Use a soft, dry cloth to clean the G1u. If necessary, slightly
moisten the cloth. Do not use abrasive cleanser, wax, or sol-
vents (such as paint thinner or cleaning alcohol), since these
may dull the finish or damage the surface.

Please keep this manual in a convenient place for
future reference.

SAFETY PRECAUTIONS / Usage Precautions

Terms Used in This Manual

This section explains some important terms that are used throughout the G1u manual.

• Effect module

As shown in the illustration above, a patch in the
G1u can be thought of as a combination of up to
eight single effects. Each such effect is referred to
as an effect module.

• Effect type

Some effect modules have several different effects
which are referred to as effect types. For example,
the MODULATION module is comprised of
chorus, flanger, pitch shifter, and other effect
types. Only one of these can be selected at a time.

• Effect parameter

All effect modules have various parameters that
can be adjusted. These are called effect parameters
or simply parameters. When thinking of an effect
module as a compact effect, the parameters change
the tone and effect intensity similar to the knobs
on the device.

• Patch

n the G1u, effect module combinations are stored

and called up in units referred to as patches. A patch
is comprised of information about the on/off status
and effect parameter settings used in each module.

• Bank

A group of ten patches is called a bank.
The memory of the G1u is comprised of a total of
20 banks, labeled with letters A to J (user-editable
banks) and numbers 0 to 9 (read-only preset
banks), as shown in the illustration at top right.

• Mode

The internal status of the G1u is referred to as the
operation mode. The function of keys and controls
differs, depending on the respective mode. Modes
of  the  G1u  include  play  mode  for  selecting  and
playing  patches,  rhythm  mode  for  playing  a
rhythm  pattern,  edit  mode  for  modifying  effects,
and store mode for saving patches.

When the batteries are

getting low, the indication

"bt" appears on the display.

When operating the G1u on

batteries, it is advisable to

disconnect the guitar cable

plug from the [INPUT] jack

when not using the unit, to

conserve battery power.

Close the cover of the

battery compartment.
