2GENERAL DESCRIPTION 2NOTE ON REPAIR WORK SAFETY
The IR-200M (hand-held type) and IR-300M (hands-free type) infrared wireless microphones are
intended for speech applications and use unidirectional electret condenser microphone units featuring
high sensitivity and clear sound.
Follow the instructions below, both to prevent accidents when making repairs and to ensure post-repair
product safety.
Do not apply voltages other than those specified for the equipment or its compo-
nents.
Applying voltages other than the rated voltage could cause electrical breakdown or over-current, possi-
bly resulting in electric shock or fire.
Do not modify the design of circuit boards or other electronic elements.
Modifying circuit boards could cause electric shock or result in a fire hazard due to excessive heat
build-up. User modification automatically exempts the manufacturer from all personal and property lia-
bility caused by such modification, and the user who carried out such modification shall be solely
responsible for such accidents.
Since lead can become an environmental contaminant, this unit has been manufactured using solders
that contain no lead in the printed circuit board.
[While conventional solders are alloys of zinc and lead, lead-free solder is comprisend of an alterna-
tive alloy that contains no lead.]
NOTES
• Circuit boards using lead-free solder bear a lead-free solder designation. To maintain the integrity
of this designation, be sure to use lead-free solder when repairing such lead-free solder circuit
boards. Boards not marked with the lead-free solder designation may legally be serviced using
conventional solders.
• Because the melting point of lead-free solder (approximately 220°C) is 30°C-40°C higher than that
of conventional (lead-zinc alloy) solder, it tasks little longer to melt. It is recommended that a sol-
dering iron with controllable temperature be used and set to 20°C higher than would normally be
used with conventional solder.
Identifying printed circuit boards that use free-lead solder
Printed circuit boards that use lead-free solder have the following designation printed or stamped on
either side of the board.

Turns on and supplies 5 V DC to the entire circuit to operate when the power
switch is turned on. Once the CPU starts operating, it controls the circuit switch.
The circuit switch turns off through OFF control and termination operations
when the power switch is turned off. It also turns off when the battery voltage
drops to 2 V or less, disconnecting the following circuits and preventing
over-discharge of battery.
