Key Description
POWER When the radio is off, this key generates a reset pulse to start the
microcontroller. The voltage stabilizer is switched on, but the radio will start
playing only after the key is released.
Pressed while the radio was on, the radio is switched off. It saves all
information about its current setting, and restores the information when
switched on again.
BAND Step cyclically through the tuning bands (not accessible in Cassette & External
mode) in the order:
FM-1 -> FM-2 -> MW -> LW -> SW -> FM-1 -> ...
FM-AST -> FM-1 -> ...
MW-AST -> MW -> ...
Depending on the installed band option diodes, the LW, MW and or SW bands
may be skipped. Depending on the option concerning the band limits and
tuning grid the LW band will be disabled (option set to USA).
When a new band is selected, the radio is tuned to the preset or frequency that
was last used in that band.
In option programming mode, this key toggles the current option:
2 SPKRS <-> 4 SPKRS
LOUD OFF <-> LOUD ON
TA LVL -2 <-> -1..0..+1..+2
