way. Be sure to insert the plugs fully. Connect the free end
of the cable to the single connector on the rear of the IRIS
Preamp.
OPERATION
For now, make sure that the four SPECIAL FUNCTION
switches
(11-I
4) are in the OUT position.
(1-5) PRESET KEYS
These keys allow five station frequencies to be STORED
into memory and recalled whenever desired.
STORING may be accomplished by first tuning to the
desired station, and then pressing the STORE key
(10)
,
followed by a PRESET key
(1-5)
,
to which this station
assignment is desired.
You may use any order of the
presets you choose.
The STORE key is intentionally located away from the
PRESET
(1-5)
keys to minimize the nuisance of accidentally
erasing your stored presets.
Recalling a PRESET station requires only pressing the
desired PRESET
(1-5)
key.
Stations preset into memory are stored indefinitely, using
a non-volatile memory. No external power or batteries are
necessary. The memory unit also provides automatic
power-up return to the station tuned at power-down.
(6-7) DOWN AND UP KEYS (MANUAL
TUNING)
Pressing either of these causes tuning changes in 50 kHz
increments (per keystroke), shown on display
(17).
HOLDING either of these causes first a slow “scrolling”,
followed, after one second, by a fast “scrolling”, of tuning
frequency.
The tuning process stops as soon as you release either
key--whether a station is present or not.
FM stations in North America are assigned only to odd
tenths of a megahertz spacing--i.e. every
200
kHz. The
