ITEC 5300 RADIO MICROPHONE SYSTEMS
With the ITEC 5300, you have a modern and professional radio microphone system in the UHF frequency
range. The receivers (the receiver module and the 19“ installation module) are True-Diversity receivers,
guaranteeing a wide range and interference-free reception without temporary cancellations. An innovative
„Pilot Tone“ procedure provides reliable protection against interference caused by external transmitters and
prevents switching clicks during switching on and off of the transmitter.

1.3. General assembly instructions
1.3.1. Positioning of the receiver
For proper operation, the receiver should be po-
sitioned as high as possible, at least, however,
1 m above the floor. The clearance from walls
and metal surfaces should also be at least 1
m. For proper operation, the transmitter (micro-
phone) must not be positioned closer than 1 m
from the receiver. Proximity to sources of inter-
ference, such as e.g.: motors, fluorescent lamps,
spotlights with ballasts, cars, mobile telephones,
computers etc. should also be avoided.

Settings:
Pressing the SET button changes the setting mode in the order listed below:
GRP (group) CH (channel) FRQ (frequency) SQ (squelch - noise suppression)
When the corresponding display flashes, the setting can be changed using the arrow keys.
Group and channel: see Appendix List of permanently programmed frequencies
Frequency: free setting of the frequency only possible in group 11!
Squelch: 1 bar (low noise suppression = high range) up to
5 bars (high noise suppression = low range)
If a transmitter is in operation in the environment, its frequency cannot be selected!
Disable/Enable by a long press of the SET button. If the button lock is active, a key symbol appears on the
display.
The frequency setting of the corresponding microphone or pocket transmitter takes place by pressing the
ACT button. For this purpose, the microphone / pocket transmitter must be switched on and the IR receiver
diode of the transmitter must be held at a distance of approximately 10 cm from the IR transmitter diode of
the receiver.
Caution: No other microphones in the vicinity may be switched on during the updating procedure. They may
otherwise accidentally receive the IR data.

3.1.2 Batteries
The WM-5300 is operated with 2 AA batteries. Please make sure that both batteries are always replaced by
new ones of the same type. When inserting the batteries, please pay attention to correct polarity. The status
of the battery is shown on the LCD display. The red LED battery status display also indicates the battery
status: when switching on, the display lights up for approximately 1 second and then goes out again. If this
indicator lights up permanently, this is a warning that signalises the low charging status of the battery.
3.1.1 Replacement of the capsule
The capsule can be unscrewed for replacement. The microphone is equipped with an electret capsule as
standard. A dynamic capsule is available upon request.
Battery change:
Unscrew the cap at the bottom end of the microphone and insert two new
batteries. Ensure correct polarity (minus pole resp. at the spring contact,
top and bottom)! Battery type: 2x Mignon “AA” 1.5V
Note: Old batteries are special waste and must be disposed of accordingly.
Some batteries (mainly cheap products) may leak in case of longer sto-
rage, which may lead to corrosion and destruction of the battery contacts.
Use high-quality alkaline batteries from brand manufacturers; these also
have a longer service life.

standard. A dynamic capsule is available upon request.
3.2.2 Lithium ion battery
The WM 5320 has a lithium ion battery of type 18500. When charging, only use the original ITEC-HC 80 char-
ger. The external charging contacts enable charging by simply placing the microphone into the charging
station without having to remove the battery. However, changing the battery and charging the removed bat-
tery are also possible (keep a spare battery for long periods of use). The operating time with a fully charged
battery is approx. 10 – 12 hours.
Replacing the lithium ion battery:
Unscrew the microphone capsule. Remove the round contact plate by pressing the two catches. The lithium
ion battery can now be easily removed. Pay attention to correct polarity when inserting the replacement
battery. The plus pole (marked by a groove) is at the top.
