Quick Start Guide
Base Station Operation
1. Power: Insert a standard 120VAC IEC power cable into the power connector located on
the back of the base station.
2. Antennas: Connect antennas to ports on back of Base Station.
3. Connect Headset: Insert the headset connector into the base station until it snaps into
place.
4. Powering Up: Press the power button. The display will turn on as well as various LEDs.
5. Tx & Rx Frequencies: Program the transmitter and receiver frequencies as desired. See
Section 6: Base Station Operation or Section 8: PC Application for information on how to
program frequencies from the Base Station itself or from the PC Application. Note: the
defaults for Rx 1 – Rx 6 are 175MHz, 176MHz, 177MHz, 178MHz, 179MHz, and 180MHz.
The default for Tx1 is 519MHz and Tx2 is 520MHz.
6. Intercom 2W / 4W:
Belt Pack
1. Batteries: Place five (5) new “AA” lithium or alkaline batteries into the provided battery
sled, in the correct polarity.
2. Connect Headset:Insert the headset connectors into the belt packs until they snap into
place.
3. Powering Up:Press the Power / Menu button that is located on the side of the belt
pack. The display will turn on and the belt pack will power on.
4. Tx & Rx Frequencies: Program the transmitter and receiver frequencies as desired. See
Section 7: Belt Pack Operation or Section 8: PC Application for information on how to
program frequencies from the Belt Pack itself or from the PC Application. Note: the
default for Rx1 is 519MHz, Rx2 is 520MHz, and Tx is 175MHz. These values will work
with the Base Station defaults for one belt pack (belt pack #1). The other belt packs will
need their frequencies changed from the defaults. See notes above.
Congratulations, your new base station is ready for use!
