MEMORY TUNING
You can manually store up to 6 AM and 12 FM stations in memory groups.
Each memory group (AM, FMI, and FMII) holds up to six stations. You can
also automatically store the first 6 strong AM and first 6 strong FM
stations in a separate automatic travel programming memory.
Storing Stations
1. Repeatedly press BND to select the desired memory group (AM, FMI, or
FMII).
2. Tune to the station you want to store.
3. Hold down the desired memory channel button until P-, the memory
channel number, and the frequency flash once on the display. The
station is stored.
Storing Stations in Automatic Travel Programming Memory
The stereo can store the first 6 strong AM and the first 6 strong FM
stations it finds into its automatic travel programming (ATP) memory.
This memory is separate from the stereo's memory groups, so it does not
replace the stations you manually stored.
1. Repeatedly press BND to select the desired band (AM, FMI, or FMII).
2. Hold down ATP (automatic travel programming) for about 2 seconds. The
stereo displays ATP, scans the selected band, and automatically stores
the first 6 strong stations it finds in automatic travel programming
memory.
After the stereo stores all six stations in the selected band, it
tunes to the first station it stored in automatic travel programming
