Usage and safety precautions
In this manual, symbols are used to highlight warnings and 
cautions that you must read to prevent accidents. The mean-
ings of these symbols are as follows:
Please observe the following precautions to ensure safe use 
of this unit.
Power requirements
Since the power consumption of this unit is high, we 
recommend using the AC adapter. When using batter-
ies, use either alkaline or nickel-metal hydride batteries.
Operation using an AC adapter
•  Be sure to use only a DC5V/1A/center plus AC adapt-
er (ZOOM AD-14). Use of an AC adapter other than
that specified could damage the unit, cause malfunc-
tion or result in a fire or other trouble.
•  Connect the AC adapter only to an outlet that sup-
plies the rated AC voltage required by the adapter. 
Before using the R24 in other countries (or regions)
where  the  power  voltage  differs  from  AC  100  V,
always consult with a store that handles ZOOM prod-
ucts and use a suitable AC adapter. 
•  When disconnecting the AC adapter from an outlet,
always pull the body of the adapter itself. 
•  During lightning storms or when not using the unit
for an extended period of time, disconnect the AC 
adapter from the AC outlet.
Operation using batteries
•  Use six conventional 1.5-volt AA batteries
•  The R24 cannot recharge batteries.
•  Read battery labels carefully.
•  When not using the unit for an extended period of
time, remove the batteries from the unit.
•  If  a  battery  leak  should  occur,  wipe  the  battery
compartment and the battery terminals carefully to 
remove all battery residue.
•  Always close the battery compartment cover when
using the unit. 
About grounding
Depending on the placement conditions of the unit, a
slight electrical charge might be felt when touching a 
metal part of the R24. If you wish to avoid this, ground
the unit by connecting an external ground to a screw on 
the rear panel. To avoid danger from electricity, never 
connect it to any of the following for grounding.
•  Water pipes (risk of electric shock)
•  Gas pipes (risk of explosion)
•  Telephone wiring grounds or lightning arrestors
 (danger during lightning strikes)
Operating environment
Avoid using the R24 where it might be exposed to the
following conditions that could cause it to malfunction.
• Extremely high or low temperatures
• Very high humidity or splashing water
• Excessive dust or sand
• Excessive vibrations
Handling
Never put vases or other items filled with liquids on the 
R24 as they could cause electric shock.
The R24 is a precision instrument. Do not put unneces-
sary pressure on the keys and other controls. Use of
excessive force and dropping or bumping the unit, for 
example, could cause the unit to break. 
Connecting cables with input and output jacks
Always turn the power OFF for all equipment before 
connecting  any  cables.  In  addition,  make  sure  to 
disconnect all connection cables and the AC adapter 
before moving the unit.
Alterations
Never open the case or attempt to modify the product 
in any way since this could result in damage to the unit. 
Zoom Corporation will not take any responsibility for 
damage resulting from alterations to the unit.
Volume
Do not use the R24 at a loud volume for a long time.
Doing so could damage hearing.
Interference with other electrical equipment
In consideration  of safety,  the R24 has been designed  to
provide maximum protection against the emission of electro-
magnetic radiation from the device and to be protected from 
external interference. However, equipment that is very sus-
ceptible to interference or that emits powerful electromagnetic 
waves could result in interference if placed near the R24. If
this occurs, place the R24 and the other device farther apart.
With any type of electronic device that uses digital control, 
including the R24, electromagnetic interference could cause
malfunction, corrupt or destroy data and result in other unex-
pected trouble. Always use caution around other devices.
Cleaning
Use a soft cloth to clean the panels of the unit if they become
dirty. If necessary, use a damp cloth that has been wrung out 
well. Never use an abrasive cleanser, wax or solvent including 
alcohol, benzene and paint thinner.
Malfunction
If the unit becomes broken or malfunctions, immediately dis-
connect the AC adapter, turn the power OFF and disconnect 
other cables. Contact the store where you bought the unit or 
Zoom service with the following information: product model, 
serial number and specific symptoms of failure or malfunction, 
along with your name, address and telephone number.
