Precautions
Follow the warnings and cautions given below when handling this instrument. This information is to be
supplemented by the warnings and cautions given in each chapter.
WARNING
• Strictly observe the following precautions. Failure to do so may place the patient
and medical personnel in danger of an electric shock.
Do not souse or spill a liquid such as water over the wireless unit. If a liquid is
spilt on it, immediately wipe it. Should a liquid penetrate the wireless unit,
immediately stop using it and contact Olympus.
Do not prepare, inspect, or use the foot switch with wet hands.
Should a liquid enter the foot switch during the battery replacement, for
example, immediately remove the batteries to prevent a fire or electric shock
hazard. Once a liquid has entered the foot switch, do not use it because the
equipment may have been damaged.
• Never install and operate the foot switch in locations where:
The concentration of oxygen is high;
Oxidizing agents (such as nitrous oxide (N2O)) are present in the atmosphere;
Flammable gases are present in the atmosphere;
Flammable liquids are near.
Otherwise, explosion or a fire may result because the foot switch is not
explosion-proof.
• Do not use for purposes other than those described in “Intended use” on page 3,
as this may result in injury of the patient or operator as well as damage to the
equipment.
• This instrument should be used under the conditions specified in “Environments”
on page 59. Otherwise, imperilment of safety or failure of equipment may result as
well as malfunction.

Important Information — Please Read Before Use
MAJ-2301 INSTRUCTION MANUAL
CAUTION
• Since this instrument has a wireless function, it may affect peripherals to be used at
the same time.
• Handle batteries by strictly observing the following. Incorrect use of batteries may
cause fluid leak, heat generation, which would lead to equipment damage.
Use batteries specified for this instrument.
Do not use charged or rechargeable batteries.
Insert batteries by observing the (+) and (–) polarity.
All batteries of the same brand name have to be used.
Do not use a battery with a broken coating.
Do not use a battery deformed by dropping or other impact.
Do not use a battery if any irregularity, including fluid leak, discoloration, and
deformation, is observed.
• Do not use this instrument in any place where it may be subject to strong
electromagnetic radiation (for example, in the vicinity of a microwave therapeutic
equipment, MRI, wireless set, short-wave therapeutic equipment, cellular/portable
phone, etc.). This may impair the performance of this instrument.
• Do not use this instrument in any place with strong magnetic force, or bring
magnetized equipment or magnets closer. This may impair the performance of this
instrument.
• Do not apply excessive force to a switch of this instrument or press it with a sharp
or hard object. Otherwise, the switch damage may result.
• Connect various connectors in a dry state without contamination of electrical
contacts. Also, do not touch the electrical contacts inside the connector directly. If
the electrical contacts are dirty or used under wet conditions, the equipment may
cause malfunction.
• Do not apply excessive force or strong impact to this instrument, ancillary
equipment, and cables. Otherwise, equipment damage or failure may result.
• Remove batteries when they are exhausted or not to be used for a long period. If
batteries are left inside the instrument, over-discharge may cause fluid leak, which
may eventually lead to a failure of this instrument.
• Remove dust and dirt from batteries before use. If the (+) or (–) pole is dirty or
dusty, a contact failure may result.

MAJ-2301 INSTRUCTION MANUAL
NOTE
Startup display icons are displayed on four corners of the observation monitor
screen for ten to twenty seconds after the power is turned ON on the surgical
microscope. Afterwards the icons will disappear. These icons are displayed until
the setup of the surgical microscope has completed and does not mean
malfunction.
Figure 1
EMC
• For safety, always use this instrument in combination with equipment compliant to the EMC
standard. Otherwise, interference from or to other equipment may result.
• The foot switch and wireless unit radiate RF energy to achieve their intended use (control of
the surgical microscope). This means that they could produce electromagnetic interferences
when they are placed in the proximity of equipment carrying the symbol marking below or
mobile and portable RF communications equipment such as a cellphone. If an
electromagnetic interference occurs, a relief measure such as displacement of interfered
equipment will be required.
• The foot switch and wireless unit incorporate the radio communication function as shown in
the following table. Consequently, they may be affected by electromagnetic interference from
nearby equipment that uses the same frequency band as them. Before using them, make
sure that there is no risk of electromagnetic interference from nearby equipment.

Summary of Equipment Functions
MAJ-2301 INSTRUCTION MANUAL
This instrument is designed to be connected to the Olympus-designated surgical microscope. By
pairing between the foot switch and wireless unit, the control signals of the surgical microscope can be
transmitted with either wireless or wired connection. The function incorporated in this instrument is
outlined below.
Note that only one foot switch can be pairing with a wireless unit.
Pairing of foot switch and wireless unit
Pairing of the foot switch and wireless unit enables wireless communication between them.
Pairing can be set using the foot switch cable provided with this instrument. Wireless control of
the functions of the surgical microscope is possible by controlling the foot switch.
Refer to Section 3.6, “Pairing”.
Wired connection of foot switch
In case the wireless signal is weak or the batteries are exhausted, the foot switch can be
connected directly to the Olympus-designated surgical microscope using the provided foot
switch cable. When the foot switch is connected through the foot switch cable, the functions of
the surgical microscope can be controlled from the foot switch even when it contains no
batteries in it.
Refer to Section 5.3, “Wired control of foot switch”.
NOTE
• The foot switch cannot control the microscope functions unless the provided
wireless unit is connected to the microscope. Be sure to connect the wireless unit
to the surgical microscope even before the wired control operation.
• Wireless communication is not performed when wired connection.
