The LED display The red LED provides information on the operating state of the transmitter. Red LED lights up normally: The transmitter is switched on and the capacitiy of the battery is sufficient (ON). Red LED is flashing: The battery is going flat (LOW BATT)! Red LED lights up brightly: The transmitter is fully modulated (PEAK).
Preparing the transmitter for use Inserting and changing the battery For powering the transmitter, use a 1.5 V AA size alkaline-manganese battery. Open the battery compartment by pushing the two catches in the direction of the arrows and open the cover . Insert the battery as shown in the diagram on the left. Please observe correct polarity when inserting the battery. Close the battery compartment.
Connecting the microphone The transmitter is designed for use with Sennheiser lavalier microphones and headmics (-4 versions). The power supply of these microphones is via the microphone input of the transmitter. Connect the microphone to the microphone input of the transmitter. Screw down the coupling ring. Connecting the antenna The transmitter is supplied with a plug-on antenna. Connect the antenna to the antenna socket of the transmitter. Screw down the coupling ring.
Attaching the transmitter to clothing The transmitter is attached to clothing (e.g. belt, waistband) with the supplied belt clip. The clip is detachable so that you can also attach the transmitter with the antenna pointing downwards. To do so, withdraw the clip from its fixing points and attach it the other way round. Using the transmitter Switching the transmitter on/off Open the battery compartment. To switch the transmitter on, briefly press the ON/OFF button .
! The transmitter can only be switched off when the lock mode is deactivated (see “The automatic lock mode (autolock function)” on page 13). To switch the transmitter off, press the ON/OFF button until “OFF” appears on the LC display panel . The red LED and the LC display panel go off. Note: ! When in the setting mode of the operating menu, the ON/OFF button will cancel your entry (ESC function).

Button Mode (UP)/ Display mode (DOWN) Function Changes to the previous parameter ( ) or changes to the next parameter ( ) Selection mode Changes to the previous menu ( ) or changes to the next menu ( ) Setting mode Increases ( ) or reduces ( ) the setting of the selected menu The automatic lock mode (autolock function) The transmitter has an automatic lock mode (autolock function) that can be activated via the “LOCK” menu (see “Activating/deactivating the automatic lock mode – LOCK” on page 25).
Deactivating th e autolock function temporarily To make changes to the settings via the operating menu, you can temporarily deactivate the lock mode. Press the ON/OFF button or the multifunction switch (switch position SET). “LOCK” appears on the LC display panel . Slide the multi-function switch to the position (UP) or (DOWN). “UNLOCK” appears on the LC display panel . Press the multi-function switch (switch position SET). You can now change the settings.
Working with the operating menu The operating menu has three modes: ! Display mode In display mode, you can display the current menu settings one after the other – even when the lock mode is activated. ! Selection mode In selection mode, you can select the menu whose setting you want to change. To change to the selection mode, the lock mode must be deactivated. ! Setting mode In setting mode, you can change the setting of the selected menu.
After switch-on After switch-on, the standard display is shown on the LC display panel . Depending on the setting, the transmission frequency, the channel number or the name of the transmitter is displayed. Displaying the menu settings in display mode In display mode, and with the lock mode activated, you can display the current menu settings one after the other (see “Overview of the operating menu” on page 19). After a few seconds, the display returns to the standard display.
The following menus are available: Menu Function of the menu CHAN Selecting a channe l TUNE Setting transmissio n frequencies for t he channel bank “VA R” (va riable bank) NAME Ent ering a name ATTEN Adjusting the micro phone sensi tivity LOWCUT Adjusting the ba ss roll-o ff frequency VIEW Selecting the sta ndard display RESET Lo ading the fa cto ry pre-set default settings POWER Adjusting the output power LOCK Act ivat ing/de act ivating the autolo ck function EXIT Exiting t he o perat
Storing a setting Press the multi-function switch SET DOWN UP (switch position SET) to permanently store a setting. “STORED” appears on the display panel, indicating that the setting has been stored. The display then returns to the top menu level. With most menus, new settings become effective immediately without having to be stored. An exception are the “TUNE” and “CHAN” menus.
Overview of the operating menu Deactivate the lock mode before adjusting the settings (see “Deactivating the autolock function temporarily” on page 14). Pressing the ON/ OFF button will cancel your entry (ESC function) and return you to the display mode. Display mode Setting mode Selection mode 530.050 1 sec. MHz CH MHz Transmission frequency 1 sec.

Adjustment tips for the operating menu Selecting a channel – CHAN Via the “CHAN” menu, you can switch between the channels in the channel banks “FIX“ and “VAR“. The transmitter is not transmitting while this adjustment is being made. When changing to the setting mode of the “CHAN” menu, the current channel number appears on the diplay. After approx. 1 second, the currently assigned transmission frequency is displayed. 1 sec.
The frequencies are tunable in 5-kHz steps within a switching bandwidth of 36 MHz max. Note: When operating a multi-channel system, make sure to only use intermodulation-free frequencies. There are two options for setting the frequencies: ! You can set a new frequency for the selected channel: In the selection mode of the “TUNE” menu, SET press the multi-function switch (switch position SET). The current channel number appears on the display and then the currently assigned frequency is displayed.
RF MHz MHz The current frequency of the selected channel is displayed. Change the frequency by sliding the multifunction switch to the position (UP) or (DOWN). Store your setting. Entering a name – NAME Via the “NAME” menu, you can enter a freely selectable name for the transmitter. This name can be displayed on the standard display and can consist of up to six characters such as: ! letters (without pronounciation marks), ! numbers from 0 to 9, ! special characters and spaces.
Adjusting the microphone sensitivity – ATTEN Via the “ATTEN” menu, you can adjust the transmitter’s sensitivity. RF AF dB The sensitivity is correctly adjusted when the level display for audio signal “AF” shows full deflection only during the loudest passages or when the redLED lights up brightly. The sensitivity can be adjusted in 1-dB steps from + 40 dB to –30 dB. Note: ! The bargraph has a resolution of approx. 3 dB per segment with a display range of 45 dB.
Loading the factory pre-set default settings – RESET Via the “RESET” menu, you can load the factory pre-set default settings. After the reset, the standard display is shown on the LC display panel. Low-cut frequency flat Microphone sensitivity 0 dB Name SK5212 Standard display frequency Autolock function deactivated Channel FIX 01 Output power high Frequencies in the channel bank “VAR” are reset.
Adjusting the output power – POWER Licensing regulations may require a limitation of the output power to 10 mW. The transmitter therefore features a switchable output power. With reduced output power, the operating time increases. Exiting the operating menu – EXIT Via the “EXIT” menu, you can exit the operating menu and return to the standard display.
If problems occur...
Tips for optimum reception ! Transmission range depends to a large extent on location and on the selected output power. There should be a “free line of sight” between transmitting and receiving antennas. ! To avoid overmodulating the receiver, observe a minimum distance of 5 m between transmitting and receiving antennas. Tips for multi-channel operation ! When operating a multi-channel system, make sure to only use intermodulation-free frequencies.
