Automatic Tuning System (ATS)
The DX-399 features an Automatic Tuning System which scans all
the available stations and stores them in sequence according to
their signal strength for quick tuning. The strongest signal station
will be tuned and stored in the fi rst available memory location, and
the second strongest signal will be tuned and stored next, and so
on until all nine memory location numbers are occupied.
To set your scanner to tune automatically, hold down •ATS for the
desired band
(FM,
LW, or MW) for about 3 seconds. The DX-399
beeps once while TUNING and ATS flash. The numbers 1- 9 ap-
pear one at a time indicating that the receiver is scanning. When
automatic tuning and memory preset is complete, the DX-399
beeps.
Notes:
• The DX-399 automatically tunes and stores up to 18 FM sta-
tions (nine in each of two memory banks - P1 and P2), 9 MW,
and 9 LW stations.
• ATS does not work in the SW band.
• Only 0 , POWER and
·o-n
controls can fu nction during an
ATS.
