Putting the diversity receiver into operation Putting the diversity receiver into operation Inserting the batteries/accupack For powering the diversity receiver, you can either use two 1.5 V AA size batteries or the rechargeable Sennheiser BA 2015 accupack (see “Accessories” on page 24). 왘 Open the battery compartment by pushing the two catches 쐈 in the direction of the arrows and open the cover 쐅. 쐅 쐈 쐂 쐅 쐂 왘 Insert the two batteries or the accupack as shown above.
Putting the diversity receiver into operation Connecting the earphones 왘 Connect the earphones to the socket 쐇. 쐇 The ground connection of the earphones cable serves as the antenna for the second diversity section. For details on the connector assignment, refer to the diagram on page 26. Attaching the diversity receiver to clothing You can use the belt clip 씍 to attach the diversity receiver to clothing (e.g. belt, waistband).
Putting the diversity receiver into operation To detach the belt clip: 왘 Lift one side of the belt clip as shown. 왘 Press down the belt clip at one fixing point and pull it out of the housing. 왘 Repeat for the other side.
Using the diversity receiver Using the diversity receiver To establish a transmission link, proceed as follows: 1. Switch the transmitter on (see the instruction manual of the transmitter). 2. Switch the diversity receiver on (see next section). The transmission link is established and the receiver’s RF level display “RF” 햲 reacts. It is vital to observe the notes on frequency selection on page 20.
Using the diversity receiver To adjust the volume: CAUTION! Danger of hearing damage! Listening at high volume levels for long periods can lead to permanent hearing defects. 왘 Set the volume to a low level before putting the earphones on. 왘 Do not continuously expose yourself to high volumes. 왘 Turn the volume control 쐃. Deactivating the lock mode temporarily You can activate or deactivate the automatic lock mode via the “Auto Lock” menu item.
Using the diversity receiver Selecting a standard display ESC 왘 Press the ESC button to select a standard display. In stereo mode you can alternatively press the UP/DOWN button 왖/왔.

Using the operating menu Using the operating menu A special feature of the Sennheiser 2000 series is the consistent, intuitive menu structure of transmitters and receivers. As a result, adjustments to the settings can be made quickly – even in stressful situations, for example on stage or during a live show or presentation.
Using the operating menu Display Function of the menu item Main menu “Menu” Squelch Adjusts the squelch threshold Easy Setup Scans for unused frequency presets, releases and selects frequency presets Frequency Preset Sets the frequency bank and the channel Name Enters a freely selectable name Balance Adjusts the balance Mode Selects stereo or Focus mode High Boost Activates/deactivates the treble boost Auto Lock Activates/deactivates the automatic lock mode Advanced Calls up the extended m
Using the operating menu Working with the operating menu If the lock mode is activated, you have to deactivate it in order to be able to work with the operating menu (see page 14). By way of example of the “Frequency Preset” menu, this section describes how to use the operating menu. Changing from a standard display to the operating menu SET 왘 Press the SET button. The current standard display is replaced by the main menu. The last called up menu item is displayed.
Using the operating menu Canceling an entry ESC 왘 Press the ESC button to cancel the entry. The current standard display appears on the display panel. To subsequently return to the last edited menu item: SET 왘 Press the SET button repeatedly until the last edited menu item appears. Exiting a menu item To return to the next higher menu level: 왘 Change to the “Exit” menu item. Menu Exit SET 왘 Confirm your selection.
Synchronizing a transmitter with the diversity receiver Synchronizing a transmitter with the diversity receiver When synchronizing the SR 2000 IEM or SR 2050 IEM transmitter with a diversity receiver, please observe the following: 왘 Only use a transmitter and a diversity receiver from the same frequency range (see the type plate on the transmitter and the diversity receiver). 왘 Make sure that the desired frequencies are listed in the enclosed frequency information sheet.
Cleaning the diversity receiver Synchronizing transmitters with diversity receivers (Sync) In a second step, you transfer the frequency bank and channel settings from the transmitters to other diversity receivers (synchronization) and thus establish the transmission links. If you want to carry out synchronization at a later time: 왘 Press the jog dial on the transmitter. The frequency bank and the channel are stored. The transmitter’s RF signal is activated again.
Recommendations and tips Recommendations and tips ... for the diversity receiver • Make sure that the antenna and the earphones cable do not cross. • For best results, make sure that the transmitter sensitivity is correctly adjusted. ... for optimum reception • Transmission range depends to a large extent on location and can vary from about 10 m to about 150 m. There should be a “free line of sight” between transmitting and receiving antennas.
If a problem occurs ... If a problem occurs ... Problem Possible cause Possible solution Diversity Lock mode is activated Deactivate the lock mode receiver cannot (see page 14). be operated, “Locked” appears on the display panel No operation indication Batteries are flat or accupack is flat Replace the batteries or recharge the accupack (see page 10). No RF signal Transmitter and receiver are not on the same channel Set the transmitter and receiver to the same channel.
Accessories Problem Possible cause Audio signal has Transmitter sensitivity a high level of is adjusted too low background noise Audio signal is distorted Possible solution Adjust the transmitter sensitivity correctly (see the instruction manual of the transmitter). Transmitter sensitivity Adjust the transmitter is adjusted too high sensitivity correctly (see the instruction manual of the transmitter).
