7.1 RF Setup
Note: Never power on an FM transmitter without a suitable antenna or dummy load
connected. The V3 transmitter’s protection circuitry will prevent any internal damage,
but it is not advisable to run a transmitter without a load connected.
7.1.1 Basic setup
1. Set the desired Frequency. Note that the frequency displayed in the status
box will flash for a few seconds, indicating that the system is out of lock and has
not yet reached that frequency. Once locked, the display will become steady.
2. Set the required Power. The system will take time to ramp the power to the
selected value. During this time, the value displayed in the status box will
flash.
3. Set the 100% modulation level: This will usually be 75kHz deviation – and should
only be adjusted under special circumstances and then with caution.
4. Select whether you require the unit to send the FSK ID every hour. If enabled,
enter the FSK ID (applies only to translator application in the USA).
5. RF Mute must be switched to off once the unit is set up, to allow it to transmit.
7.1.2 Power Scheduler
This feature will switch the output power of the unit to an alternate value set in Power
Scheduler | Power during the selected time interval. This is to allow you to lower the
power of the transmitter, for example at night, to reduce power consumption.
To set up this feature, enter the Power Scheduler sub-menu:
1. In Power set the power that the unit will switch to during the scheduled
interval;
2. Set the start time at which the unit will switch to this power level;
3. Set the finish time, when the unit will switch back to its normal power level;
4. Current time is the system time. This is displayed here as a reference for use
when setting the start and finish times. It can be adjusted if required.
5. Set Enable to On. The power scheduler is now running.
