The S-Meter is displayed on top of the VFO frequency. The user can refer to this when giving a signal strength report to the station they are working.
To the right of the S-Meter is the battery voltage monitor. This is used to quickly gauge the condition of the battery. It’s recommended not to operate the radio below 6V to avoid damaging the batteries.
When the radio goes into transmit, the SWR and output power are shown instead of the S-meter.
The VFO frequency is displayed below the S-Meter. It indicates the VFO in use (A/B), and the frequency that the radio will transmit on.
When RIT is on, the VFO displays the RX frequency, while maintaining the previously chosen transmit frequency. Use this when Dxing or contesting to receive stations that are slightly away from your own transmitting frequency.
