MASK mode
During AF search, PI stations and non-RDS (Radio Data Station) stations with strong
signal will be masked, in the latter case, the non-RDS stations may cause interference,
resulting the real AF to be masked due to the misjudgment of the radio under
interference. Rotate the VOL knob to select the desired mode: MASK DPI and MASK ALL.
-
MASK DPI: To mask only the AF with different PI.
-
MASK ALL: To mask both PI and strong signal non-RDS station.
