S3500, S4000 & S4000F Handheld Transmitters:
•
Setting Up:
For the S4000 & S4000F, screw the external helical antenna into the antenna connector on the base of the microphone. For maximum range and
performance it is important not to place your hand around this antenna whilst the microphone is in operation. The S3500 handheld microphones have a built in
antenna.
Turn the microphone’s collar round to the left and gently slide down the body shell to reveal the battery compartment. Insert a 9v (MN1604) battery observing
the correct polarity. Close the body shell and turn the collar back to lock it in place.
Switch on the microphone using the switch on its base. The LED will light up if the battery is good. Note that the LED will extinguish when the battery needs
replacing. On the S3500 and S4000, the LCD display will also indicate the current channel and bank - the bank is indicated at the bottom of the display.
•
Changing the Transmitting Channel - S3500 & S4000 only:
Sliding open the body of the microphone as described above will not only reveal the battery compartment, but also two small push button switches. These are
located on the opposite side of the microphone to the battery compartment, adjacent to the LCD.
Whilst the microphone is switched on, press and hold the switch nearest to the base of the microphone until
FrEq
is displayed on the LCD. Releasing the
switch at this stage will advance the transmitting frequency to the next frequency in the current bank. Continuing to hold down the switch will scroll through the
available frequencies in the current bank, and whatever frequency is displayed when the switch is released will be chosen as the transmitting frequency. This
setting is stored in memory within the microphone and will be retained even when the microphone is switched off.
The exact selection of channels available in each bank will depend on how the transmitter has been programmed in the factory. It can contain up to 32
unique channels, which can be arranged in up to 4 banks, but your transmitter will not necessarily contain this many channels or banks.
•
Changing the Current Bank - S3500 & S4000 only:
Slide open the microphone body and locate the two push button switches as described above.
Whilst the microphone is switched on, press and hold the switch nearest the LCD until
BAnc
is displayed on the LCD. The current bank (displayed at the
bottom of the LCD) will then scroll through the available banks (up to 4 in total). Release the switch when the desired bank is shown, and this will become the
current bank. After changing the current bank, it will probably be necessary to choose the desired transmitting frequency from the new bank as described
above. This setting, like the transmitting frequency, is stored in memory and will be retained even when the microphone is switched off.
As already mentioned above, the exact selection of banks available will depend on how the transmitter has been programmed in the factory. There can be
up to 4 banks, but if there is only 1, this option will not be functional
.

Changing the Audio Gain - S3500 & S4000 only:
Locate the two push button switches as described above and press them both down together. After a short delay,
GAIn
will be displayed on the LCD along
with a number from 0 to 9. This number is the current gain setting. Continuing to hold down only the right hand switch (nearest the LCD) will increase the gain
up to the maximum of 9, whilst holding down only the left hand switch will decrease the gain down to the minimum of 0. When neither switch has been
pressed for a period of time, the display will revert to showing the transmitting frequency, and the new gain will have been selected and stored. Refer to the
receiver instructions for details on how to optimise the gain of your system to best suit the application for which it is to be used. Normally setting 9 (maximum)
will be best for low SPL level microphone applications such as interviews and conferences and gain 0 (minimum) is best for high SPL level applications such
as stage use with high vocals. The gain is initially set to 5 or 6 in the factory. Note that the S4000F has its gain optimised in the factory.
