Quick Start Guide
BASE STATION
1. POWER: Insert power supply plug into the power connector located on the back of the Base Station
and connect Standard 120v IEC power cord to power supply.
2. ANTENNAS: Connect the supplied antennas to ports on back of Base Station. For proper
performance, adjust antenna length for the desired frequency using the tuning chart found on the
antenna.
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 the Base Station Operation section or the UV-1G PC Application (supplied) for information on
how to program frequencies from the Base Station itself.
NOTE: the defaults for Rx 1 – Rx 6 are 175MHz, 176MHz, 177MHz, 178MHz, 17 MHz, and 180MHz.
The default for Tx1 is 51 MHz and Tx2 is 520MHz.
6. INTERCOM 2W / 4W: For 2W intercom, select Audiocom (Telex), Clear-Com, or RTS mode via the
menu. Enable the 2W or 4W intercom using the intercom 1 and 2 select buttons (see Front Panel
Button Descriptions).
After connecting the UV-1G 2W intercom to an external 2W device, the given intercom channel
(CH1 or CH2) must tune itself for maximizing the nulling of undesirable audio artifacts. Upon power-
up, the Base Station will automatically perform the 2W tuning process, which consists of a low level
of white noise being sent on the given 2W channel line for a few seconds. When the tuning process
is complete, the wired intercom is ready to use. If a wired intercom is connected while the UV-1G
Base Station is powered on, the tuning process needs to be manually started by the user. This can
be achieved by pressing the Intercom Select button (CH1 or CH2) until the intercom goes from the
disabled state to the enabled state, at which point the tuning process will begin.
This tuning process is only for wired 2W intercoms. It does not affect the 4W intercoms.
BELT PACK
BATTERIES: Place battery pack (with five (5) new Energizer L 1 AA Lithium batteries, or equivalent into the
provided battery sled as indicated) in Belt Pack. If using UV-1 Li-ion Rechargeable Battery, be sure to fully
charge the batteries prior to use.
1. CONNECT HEADSET: Insert the headset connectors into the Belt Packs until they snap into place.
2. 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.
3. TX & RX FREQUENCIES: Program the transmitter and receiver frequencies as desired. See Belt Pack
Operation section or PC Application for information on how to program frequencies from the Belt Pack
itself. Note: the default for Rx1 is 51 MHz, 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 UV-1G IS READY FOR USE!
