Tunable Frequencies, Channel Separation, Reference Frequency, and Intermediate Frequency
Stores six stations in each band (FM1/FM2/FM3/AM), giving a total of 24 stations.
Tunes to the stations stored in the preset memory, holding each station for about five seconds, in each of the
FM1, FM2, FM3, and AM bands.
Searches through the entire frequency range of the received bands and stores the frequencies of the detected
stations in the preset memory.
Stores the frequency of the most-recently received station in each of the FM1, FM2, FM3, and AM bands, totaling
four stations.
Automatically starts auto-tuning if the SD signal is not detected for about 30 seconds during broadcast reception.
Also starts seek up if traffic information is not received for four seconds in TP/SK mode.

Tunable frequency
Each time one of these keys is pressed, the frequency is increased or reduced by one step,
respectively. If either of the keys is held down, the frequency is increased or reduced in high-
speed mode until the key is released.
Search for a station, moving either up or down through the frequency range, respectively.
When a station is detected, the corresponding frequency is retained.
