5 Battery or accupack operation

The EK 3053-U can be powered by either batteries or rechargeable accupacks. We recommend using a 9 V PP3 battery (IEC 6 LR 61). If powered by a 9 V PP3 battery, the receiver has an operating time of approx. five hours with the volume set to a medium value. Since the power consumption depends to a large extent on the volume adjustment on the EK 3053-U, the operating time will be reduced by up to 30 % if the volume is set to a high value. The operating time can be increased by up to 20 % if you choose a low volume. If the receiver is operated with a rechargeable 9 V accupack, the operating time will be reduced to less than two hours.

6 Inserting / Changing the battery

Slide the cover of the battery compartment towards the bottom side of the receiver, then open the cover. Insert the 9 V PP3 battery as shown above. Close the battery compartment by carrying out the operating steps in reverse order.

To remove the battery, push the small lever	in the battery
compartment towards the bottom side of the receiver.

Note

Please observe correct polarity when inserting the battery!

7 Connecting the antenna

Screw the supplied antenna onto the Lemo socket on the EK 3053- U.

8 Connecting the headphones

Connect the headphones to the 3.5 mm Ø stereo jack on the EK 3053-U. If you use the receiver as part of the in-ear monitoring system, please connect in-ear headphones. If you use the receiver for other applications, you can also connect any Sennheiser stereo headphones.

	Note
	Only connect headphones with a stereo jack plug to the
	3.5 mm Ø stereo jack !
9	Setting the receiving frequency

Slide back the coverplate . Use the channel selector switch to set the desired receiving frequency. The assignment of a switch position to a frequency is listed on the type plate on the back of the receiver. Up to 16 receiving frequencies are available.

Note

Transmitter and receiver must be set to the same frequency!

10 Switching the receiver on

Turn the volume control clockwise (the volume control has an inte- gral on/off switch - the receiver is switched off when the control is turned fully anti-clockwise until it clicks).
