2. GENERAL DESCRIPTION
WM-5420 is a multifunctional press-to-talk wireless microphone, employing a unidirectional condenser microphone unit.
3. FEATURES
An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient temperature or
voltage fluctuation.
Locking the talk switch and switchable the microphone sensitivity allows the hands-free usage..
Employs a chime function.
Transmitter channels may be configured with various functions to be used for different purposes.
Equipped with external microphone input. It is available to turn on/off using the switch on the external microphone.
Curved shape fits into user’s hand
Power/Battery lamps indicate battery consumption to prevent the unit from malfunctioning when the battery level
remarkably decreases.
Operates on a single AA battery..
Antimicrobial surface treatment.
Employs a built-in antenna.
4. HANDLING PRECAUTIONS
Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may
result in unit failure.
Never open nor remove the unit case to modify the unit. Refer all servicing to your nearest TOA dealer.
Take care not to drop the unit onto the floor nor bump it against a hard object as the unit could fail.
Do not place the unit in locations of high temperature (ex. in an ill-ventilated car in summer) or high humidity as the unit
could fail.
Do not use the unit in locations where it is exposed to seawater.
To clean, use a dry cloth. When the unit gets very dirty, wipe lightly with a cloth damped in a dilute neutral cleanser,
then wipe with a dry cloth. Never use benzine, thinner, or chemically-treated cleaning towel.
Avoid using a mobile telephone near the wireless microphone in use. Noise could be picked up.
When using two or more wireless microphones, keep them at least 50 cm away from each other to avoid malfunctions
or noise.
Keep the wireless microphone at least 3 m away from the receiving antenna. Using the microphone in close proximity
to the antenna could result in malfunctions or noise.

Note
Setting should be done when talk-switch is off.
If you change setting when the power is on, the transmission frequency will not be changed.
Refer to the frequency table when setting. If you configure a bank or channel that is not on the frequency table, signals
will not be transmitted. When the setting is incorrect or done improperly, the red and green indicators of the
power/Battery lamps will blink alternately, indicating an error. Check again and reconfigure your setting.
Step1. Turn off the talk-switch. Remove battery cover.
Step2. Using the supplied screwdriver, set the BANK setting switch to
the desired bank number.
Step3. Using the supplied screwdriver, set the CHANNEL setting
switch (A) and (B) to the desired channel number.
* If not using the A/B switch function, set (A) and (B) to the
same channel.
Step4. Replace the battery cover.
8. OPERATION
Step1. Confirm that the wireless microphone and the wireless tuner are identical in the channel number. If not identical,
turn off the talk switch, then set the channel number to the same channel number as the tuner.
Step2. Press talk switch to turn on the wireless microphone.*
Both green and red indicators on the Power/Battery lamps will flash and
either green or red indicator will remain lit depending on battery power,
microphone is then turned on.
Step3. After use, press talk switch to turn off microphone.*
*When talk switch is set as “unlocked” (default setting), it will only be on when it
is pressed and off when released.
When it is set as “locked”, press once for on and press again for off.

9. A/B SWITCH FUNCTION AND USAGE METHOD
WM-5420 sets different combinations of channels
and functions as mode A or mode B. By switching
the A/B modes, one microphone can be used in
two different ways. The following may be
configured differently for mode A and mode B:
Channel number
Talk switch option
Chime option
Microphone sensitivity option
* All other settings except those above are
common for both modes.
[Operation]
Step1. Slide the A/B switch to choose “A” or “B”.
Step2. Press talk switch to turn on microphone.

The external talk-switch on the optional microphone is
not available.
The external talk-switch on the optional microphone is
available.
WM-5420 internal talk-switch is also available to turn
on/off using talk switch. However, if either one of
internal or external talk-switch is turned on, it is not
available to turn off by the other talk-switch.
Note
If the external microphone function is set to “on”, WM-5420 will sometimes turn on when the external microphone is
being plugged or unplugged.
Check if WM-5420 is on/off using Power/Battery lamps when plugging or unplugging external microphone. When WM-
5420 is on, use the talk-switch on WM-5420 or the external microphone to turn “off”.

15. TROUBLESHOOTING
Problem Possible Causes Solution
Power/Battery lamps does not light
(for both red and green indicators)
even when the microphone is
turned on.
Is the battery polarity correct?
Is the battery capacity low?
Replace the battery correctly.
Replace with new battery.
Interference from other wireless
microphones used at the same
time.
Is other wireless microphones set the
same bank number and different
channel number?
Is the distance between wireless
microphones too close?
Is the wireless microphone too close
to the antenna?
Refer to frequency table and reset
Bank/Channel.
Keep a distance of at least 50cm
between microphones when using.
Keep a distance of at least 3m between
wireless microphone and antenna when
using. (*Depending on the antenna
location and the coaxial cable length.)
Sometimes the chime is not
activated.
Are the A/B switch and the chime
switch set correctly?
Have you turned on the microphone
immediately (within one second) after
turning it off?
Ensure correct setting.
This is normal.
Do not turn on the microphone within
one second of turning it off. Incorrect
operation may cause the chime to
repeat continuously.
