When DUAL watch is activated, “DUAL“ is displayed on the lowest line.
The pointer next to the DUAL display indicates the frequency on which
there is reception.
The Active frequency always has priority, so the receiver remains on the
Active frequency as long as there is reception on the Active frequency.
When there is no reception on both the Active frequency and the Standby
frequency the receiver scans both frequencies 5 times per second.
When there is reception on the Standby frequency the receiver stays on
the Standby frequency, however it switches to the Active frequency every 2
seconds for 0.3 seconds. When reception is detected on the Active
frequency the receiver stays on the Active frequency.
The pointer next to the DUAL display indicates on which frequency there is
reception.
