Base Transmitter Settings:
You can set up the base transmitters from the Configure tab >Edit Base Transmitters box
>Base>Transmitters
as shown below:
Base Station Transmitter Power:
For the particular transmitter, Tx1 or Tx2, you can set the power level at 1, 10, 100 or 250mW from
the Configure tab >Edit Base Transmitters box >Base>Transmitters >upper table>Power column.
To change the Off/On status of the transmitter, select the Off, On, or IFB button (to enable IFB mode
only usable with dual receiver Beltpacs) in the corresponding upper table> Enable column.
NOTE: Use the lowest power level that provides sufficient range. Using too much power when
Beltpacs are close to the base will decrease performance.
Base Station Transmitter Frequency:
As shown above in the Configure tab >Edit Base Transmitters box >Base>Transmitters>upper
table>Frequency column, you can click to reveal the frequency editing form. Click on the Group to
select frequencies P1 – P4, S1 – S4 and T1 – T4 (presets in the system that cannot be changed).
Frequencies U1 – U16 can be adjusted and saved by the user. If you select a user frequency, U1 –
U16, move the cursor to the frequency box and use the up and down arrow buttons to select a
frequency. User frequencies can be selected in 25 kHz increments.
You must click on OK to save your frequency changes.
NOTE: Frequencies within the same group (P, S or T) are compatible with each other and free of
intermodulation. Never use frequencies closer to each other than 500 kHz. Because base
transmitters share the same antenna and are more powerful than those in the Beltpacs, the
frequencies must be further apart.
