ITEC RADIO MICROPHONE SYSTEMS
WiththeITEC716-AyouhaveamodernandprofessionalradiomicrophonesystemintheVHFfrequencyrange.
The receivers (the receiver module and the 19“ installation model) are True-Diversity receivers, guaranteeing
wide range and interference-free reception without temporary dropouts.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.
For each device type, two frequency variants (EUV 232 and EUV 243) are available. In every variant are
8 different frequencies adjustable (see point 5, frequency list).
1. Introduction
1.1. System components - Overview
Transmitter

1.3. General assembly instructions
1.3.1. Positioning of the receiver
For proper operation, the receiver should be
positioned 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 (microphone)
must not be positioned closer than 1 m from the
receiver. Proximity to sources of interference,
such as e.g.: motors, fluorescent lamps, spot-
lights, cars, mobile telephones, computers etc.
should also be avoided.
Especially for WiFi routers a distance of a few
meters is recommended!
1.3.2. Assembly of the receivers in the 19“ rack
The ITEC SDR 2716-A is suitable for installation in 19 „racks.
There are two different sets of mounting brackets available.
Installation of one receiver with mounting bracket set FB 71-A
Installation of two receivers with mounting bracket set FB 72-A
In case of rack installation, the use of external antennas is recommended.

Frequency adjustment:
There are two frequency ranges (EUV232 and EUV243) with 8 adjustable channels each (see point 5,
Frequency list). The range is defined by the respective variant and can not be changed.
The channel setting on the receiver is made using the „Channel / “ buttons. To avoid unintentional ad-
justment, the buttons are normally locked. To unlock, press both buttons simultaneously for about 5 seconds
until the display flashes. Now use the / buttons to select the channel. After a few seconds, the display
automatically switches from flashing mode to permanent mode, the channel is now set and the buttons are
locked again.
Attention: During adjustment, the microphone should be off because a „busy“ channel can not be selected.

3. Hand-held Microphones or transmitters
3.1 Hand-held microphone ITEC WM-716-A
Battery indicator:
The red / green battery status indicator indicates the battery condition: when turned on, the indicator lights
red for about 1 second and then turns green. If it is constantly red, this is a warning that indicates the weak
state of the batteries.
Changing the batteries:
Unscrew the cap at the bottom of the microphone.
Always both batteries are to be replaced.
Be careful when inserting the batteries (see picture,
insert both batteries with the plus pole upwards).
Battery type: 2 pcs. „AA“ (Mignon), 1.5V.
Annotation:
Old batteries are hazardous waste and must be disposed of accordingly.
Some batteries (especially low-priced products) may leak if stored for a long time, leading to corrosion and
destruction of the battery contacts and the PCB. Use high quality alkaline batteries, these also allow a longer
operating time.
Regargeable Batteries:
Alternatively, the wireless microphone WM-716-Acan also be operated with two pieces of NiMh regargeable
batteries of size „AA“. Use the original charging station HC-92 for charging.
Never insert a microphone with a normal battery into the charging station.
Frequency adjustment:
Unscrew the cap at the bottom of the microphone.
Turn the rotary switch to the desired
channel with a small screwdriver (see point 5, frequency list).
Adjust with the microphone switched off or
after setting, turn micro on / off again so that
new selection is accepted.

3.2. Beltback transmitter ITEC WT-716-A
Battery indicator:
The red / green battery status indicator indicates the battery condition: when turned on, the indicator lights
red for about 1 second and then turns green. If it is constantly red, this is a warning that indicates the weak
state of the batteries.
Changing the batteries:
Open hinged lid, press the two snapper left and
right at the same time. Always both batteries are to be replaced.
Be careful when inserting the batteries (see picture, insert batteries with
the negative pole at the spring contact).
Battery type: 2 pcs. „AA“ (Mignon), 1.5V.
Annotation:
Old batteries are hazardous waste and must be disposed of accordingly.
Some batteries (especially low-priced products) may leak if stored for a long time, leading to corrosion and
destruction of the battery contacts and the PCB. Use high quality alkaline batteries, these also allow a longer
operating time.
Regargeable Batteries:
Alternatively, the wireless microphone WM-716-Acan also be operated with two pieces of NiMh regargeable
batteries of size „AA“. Use the original charging station HC-92 for charging.
Never insert with a microphone with a battery into the charging station.
Frequency adjustment:
Open hinged lid and turn the rotary switch to the desired
channel with a small screwdriver (see point 5, frequency list).
Adjust with the transmitter switched off or after setting, switch
the transmitter on / off again, so that new selection is accepted.
Furthermore, there are two controls in this area for adjusting the
volume of different microphones. If you get transmitter and
microphone from ITEC, an optimal setting has already been made.
Therefore, make changes to these controllers only in exceptional cases.
„MT“ adjusts the level of a microphone and „GT“ that of a guitar or a transmission cable.

4. The charging station HC-92
The charging station HC-92 can be used to charge handheld microphones of the type WM-716-A as well as
beltpack transmitters of the type WT-716-A.
In total, two of these units can be charged simultaneously - in any combination.
Attention: Never place a device that is equipped with normal batteries in the charging station.
Only suitable for handheld microphones or bodypack transmitters with
original ITEC NiMh batteries 1.5V, „AA“.
The charging station should be connected to a wall outlet with the associated 230VAC / 12VDC power
adapter.
Charging indication:
Flashing red: charging station is free or batteries are defective or contact is not correct
Solid red: battery is charging
Solid green: Battery is fully charged
Microphones or transmitters must be switched off during the charging process.
A complete charge (with NiMh 2100mAh batteries) will take
about 5 hours. Do not leave Charging station unattendet
during charging.
