FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Parts 74, 15, and 90 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
1 Safety and Environment 1. Do not spill any liquids on the equipment and do not drop any objects through the ventilation slots in the equipment. 2. The equipment may be used in dry rooms only. 3. The equipment may be opened, serviced, and repaired by authorized personnel only. The equipment contains no user-serviceable parts. 4.
2 Description 2.3 Optional Accessories • CU 400 charger • PSU 4000 central power supply • SRA 1 (shown), SRA 2 B, RA 4000 B remote antennas • MK PS antenna cable • PS 4000 antenna splitter • Color Coding Kit • AB 4000 antenna booster • Front panel mounting kit for supplied antennas • HPA 4000 headphone amplifier • W 880 windscreen for HT 400, remote MUTE switch for PT 400 (not shown) 2.
2 Description 4 ID: If you use the receiver within a multichannel system, you can color-code each channel. Remove the transparent ID cap, replace the black plastic tab with a different-color tab from the optional Color Coding Kit, and replace the transparent cap. 5 RF LEDs: The green LED is lit to indicate the receiver is receiving RF signal, the red LED indicates that no signal is being received. 6 A and B diversity LEDs: These two LEDs are lit to indicate which of the two antennas is currently active.
3 Setting Up Important! Prior to setting up your WMS 400, check that the transmitter and receiver are tuned to the same frequency, referring to sections 3.8 and 3.9. 3.1 Inserting the Transmitter Battery Refer to fig. 5. 1. Open the battery compartment cover (1). 2. Insert the supplied battery (2) into the battery compartment, aligning the battery with the polarity symbols. If you insert the battery the wrong way, the transmitter will not be powered. 3. Close the battery compartment cover (1).
3 Setting Up ((Screenshot SR 400)) If power to the transmitter is OFF or the RF level at the antennas is zero for some other reason (e.g., shadow effects), the red RF LED will be lit and the audio output will be muted. If the antennas receive RF signal, the green RF LED will be lit, the RF bargraph will indicate the field strength of the signal received by the active antenna, and the Diversity LEDs will indicate which antenna is currently active.
3 Setting Up 3.8.1 Selecting Frequency Groups (Auto Group Setup) AUTO GROUP Use and to select the number of required channels between "1" (minimum) for a single-channel system and "12" (maximum) for a 12-channel system.

3 Setting Up 3. Set the ON-MUTE/PRG-OFF switch (19) to "MUTE/PRG". The display will alternately indicate the currently selected frequency and "Prg IR". The status LED (20) remains dark. 4. Refer to Diagram 7. PRG IR IR >PRG IR< IR >EXIT< IR IR >TX OFF/ PRG IR< Refer to fig. 11. Point the infrared sensor (1) on the transmitter at the infrared emitter (2) on the receiver from a distance of 4 inches (10 cm) max.
3 Setting Up Audio input pinout: Pin 1: shield Pin 2: audio (inphase) Pin 3: audio A positive supply voltage of 6 volts for condenser microphones is available on pin 2. Please note that AKG cannot guarantee that the PT 400 bodypack transmitter will work perfectly with products from other manufacturers and any damage that may result from such use is not covered by the AKG warranty scheme. Important! 1.
3 Setting Up • The first storage locations are assigned to dropouts, the last two for the lowest RF level and highest audio level measured (Examples 2 and 3). Example 2: Minimum RF level: -90 dB Example 3: Maximum audio level: 0 dB • The last item in the result list is followed (the first item preceded) by the "EXIT" option. 3.10.
4 Operating Notes If you have not stored a receiver name yet, you can use the "NAME" screen to assign a new name to your receiver. EXTRA X-TRA 4.1.3 Extra Functions • NAME >NAME< X-TRA NAME >_< Use and to select the first character. NAME "B>_<" Use and to select the second character, etc….

4 Operating Notes The display indicates the frequency in MHz - frequency in Preset form - "Prg IR" and changes to alternating between the currently selected Preset and "Prg IR". • If you switched from "ON" to "MUTE/PRG": The microphone is muted and the status LED (20) will change from green to red. The infrared receiver section is OFF. Since the RF section continues transmitting the carrier frequency, no unwanted noises will become audible form the sound system.
6 Troubleshooting Problem No sound. Possible Cause Remedy 1. AC adapter is not connected to receiver and/or power outlet. 2. Receiver is OFF. 3. Receiver is not connected to mixer or amplifier. 4. Microphone or instrument is not connected to bodypack transmitter. 5. Transmitter is tuned to different frequency than receiver. 6. Transmitter is "OFF" or transmitter MUTE switch at "MUTE". 7. Transmitter batteries are not inserted properly. 8. Transmitter batteries/battery pack dead. 9.
