To connect a pair of headphones to the receiver, you will need an optional MK HP
adapter cable from AKG. This cable provides a mini XLR connector and a TS mini
jack for connecting headphones with a mini jack plug.

In order to avoid overloading the headphone amplifier, do not connect
headphones with an impedance of less than 16 

to the headphone out-

put.

1. Plug the mini XLR connector on the adapter cable into the AUDIO OUT 

jack (1r) on the receiver.

2. Connect the headphones to the mini jack on the adapter cable.
3. Use the rotary control (1e) to set the volume level for the headphones.

The optional MK HP/C Y cable from AKG lets you connect the receiver to a cam-
corder or mixing console and monitor the received signal using headphones with
a mini jack plug.

In order to avoid overloading the headphone amplifier, do not connect
headphones with an impedance of less than 16 

to the headphone out-

put.

1. Plug the mini XLR connector on the Y cable into the AUDIO OUT jack (1r) on

the receiver.

2. Plug the XLR connector on the Y cable into the desired XLR input jack on the

camcorder or mixing console.

3. Connect the headphones to the mini jack on the Y cable.
4. Use the rotary control (1e) to set the volume level for the headphones.

The line output level is not adjustable.

For optimum reception, point each antenna (1g) away from the receiver at an
angle of 45 degrees. With the antennas aligned like this, the diversity function will
operate optimally and prevent disturbances such as noise or dropouts most 
efficiently.
If you wear the receiver on the belt it makes no difference whether you point the
antennas (1g) up or down as long as you align them in a "V" as described above.
If you mount the receiver on a camcorder, align the antennas in the same way and
make sure the antennas (1g) will protrude above the camera case. This will pre-
vent dropouts due to shadow effects of the camera case.

To replace the black color code platelet (1) on the receiver with a different-color
platelet from the optional CC 60 Color Coding Kit,

1. Lift the end of the black color code platelet (1h) on the top panel of the receiv-

er and remove the color code platelet (1h).

2. Select a color code platelet of the desired color from the CC 60 Color Coding

Kit and snap the selected platelet onto the receiver.
