7. Frequencies

The transmitter and receiver of your WMS 80 system have been
factory programmed for up to 15 selectable carrier frequencies.
The carrier frequency label (1k) on the receiver, (2g) on the hand-
held transmitter, or (3k) on the bodypack transmitter lists the
Frequency Set your WMS 80 system uses and all available carrier
frequencies.

7.1. Frequency Sets

Prior to powering up your WMS 80 system, check that the trans-
mitter and receiver use the same Frequency Set. If they do not, you
may not be able to find a common carrier frequency for the trans-
mitter and receiver.
The following Frequency Sets are currently available:
Designation Frequency
Range (MHz)
EU58 770,6 - 773,4
EU59 777,6 - 780,4
EU60 785,6 - 788,4
JPA 802,5 - 805,5
NZ1 812,2 - 815,0
NZ2 833,2 - 835,0
UK69A 854,9 - 857,625
UK69B 858,2 - 860,9
US54 710,2 - 713,0
US55 719,0 - 721,8
US58 734,4 - 737,2
US59 742,8 - 745,6
For frequencies allocated in the various countries and frequencies
suited for intermodulation-free simultaneous operation, refer to the
Frequency List in section 12.
7.2. Ordering Transmitters and Receivers
If you want to order additional transmitters or receivers operating
on the same set of frequencies as your original equipment, be sure
to state the designation of your original Frequency Set (1k/1l, 2i,
3k/3l) and the serial number of the original device. We need this
information to make sure your new equipment will be compatible
with the original units.

8. Multichannel Systems

Carrier frequencies allocated to wireless microphones differ from
country to countr y. Depending on local frequency allocations and
available carrier frequencies you can operate two to four
WMS 80 systems simultaneously. (Refer to the Frequency List in
section 12.)
In each carrier frequency table (1k, 2h, 3k) and in the Frequency
List in section 12, the basic frequencies you can use simulta-
neously and without risk of intermodulation are marked with *.
If you have any questions regarding allocated frequencies contact
your dealer, the competent authority, your AKG representative, or
the AKG head office in Vienna, Austria.
Alternatively, you are welcome to visit the AKG website at
www.akg-acoustics.com where you can download a FREE fre-
quency management program for AKG Wireless Microphone
Systems.

9. Setting Up

Prior to connecting the receiver to AC power and inserting the bat-
teries into the transmitter, set the transmitter and receiver to the
same carrier frequency. The carrier frequency tables on the trans-
mitter (2h, 3k) and receiver (1k) and the Frequency List (section 12)
on page 44 list the channel number corresponding to each carri -
er frequency.
