*1.Preset tuning
The preset tuning is a system by which any desired broad-
cast station which has been preset by using one of the
preset-tuning buttons can be tuned by simply touching one
button.
*2. Most-recent memory
The most-recent memory is a system by which the unit
“remembers” the FM or AM broadcast station last heard

This unit includes an AM loop antenna. No outdoor antenna is
necessary unless the broadcast signals in your area are
especially weak. (Connect the loop antenna even if an outdoor
antenna is used; if it is not connected, AM reception will not be
possible.)
E Installation of the AM loop antenna
Pay attention to the following points when attaching the
antenna.
1)Do not attach it horizontally (to do so would impair
reception).
2) Do not attach it close to metal surfaces (to do so would
result in noise).
3) Do not attach it close to power cords, speaker wires, etc.
(to do so would result in noise).
4) Do not attach it close to a tape deck (when the tape deck is
being used, chirping or beeping sounds may be received).
1. Connect the AM loop antenna to the AM antenna terminals
located on the rear panel of the unit.
2. Find the height and direction of the antenna where reception
is best and then fix it vertically to the wall, rack, etc.
1) When attaching the antenna to a wall, cloumn or rack.

Sirviéndose de un destornillador (-), poner el selector de voltaje
(ubicado en el panel de abajo) a la posición que corresponda al
voltaje de la región en que habrá de ser usado el aparato.
Es de recordar que de no hacer este ajuste como es debido, el
aparato resultará seriamente perjudicado.
(En el caso de algunos países, no hay selector de voltaje; el
voltaje ya viene puesto como es debido.)
