3 Setting Up
If the receiver finds no clean frequencies:
•
Check the antenna system.
•
Slowly increase the squelch threshold from -100 dBm to -82 dBm.
Make sure never to set the squelch threshold any higher than absolutely nec-
essary. The higher the squelch threshold (-82 dB = max., -100 dB = min.), the
lower the sensitivity of the receiver and thus the usable range between transmit-
ter and receiver.
1. Select the "GROUP/CHANNEL" menu.
The currently active GROUP starts flashing.
2. Confirm the selected GROUP or use the arrow keys to select a different GROUP.
3. Having selected and confirmed a GROUP, you can use the arrow keys to select
any CHANNEL within this GROUP.
4. Select a CHANNEL to which you wish to program your system.
5. Program the transmitter to the same GROUP and CHANNEL referring to the
section on "Selecting Frequencies from the Preset Screen".

1. Insert the earbuds into your ears. The earbuds are marked "L" (left) and "R"

2. Route the cable above your ears to the back of your head and slide the cable
sheath up far enough to make the cable rest snugly against your neck.
3. Plug the mini jack connector into the HP OUT jack on the receiver.
4. Use the rotary control on the receiver to set the desired volume.

with your IVM 4500.
