Section III
OPERATING THE 632 RECEIVER
Menu Navigation Basics
If, like most of us, you’ve allowed youthful enthusiasm to
override methodical procedure, you’ve either already fig-
ured out the 632 receiver menu for yourself, or you are
ready to throw this
INO
mini
under the wheels of a passing
locomotive.
Quite simply, you turn the knob to navigate from one menu
to the next, push the knob to enter any menu associated
with receiver setup, turn the knob to set a value, and then
push again to accept the selection and return to menu navi-
gation.
In setup menus, any parameter that can be edited will begin
blinking when the knob is pushed-in. This shows that a new
value may be selected. Turn the knob to select a new value,
and then push once again to choose the selection and trans-
fer that selection to non-volatile memory.
Each Model 632 menu will be discussed separately, both for
the analog FM reception mode and the HD Radio digital-
reception mode.
Wait! What’s all that flashing???
The 632 has three alarms that indicate reception problems.
These are detailed later in the manual, but you may already
have noticed a front-panel flashing alarm. ‘Flashing’ alarms
accompany the alarm ID with large lighted block areas,
which can be seen across a room, like the
LOW SIGNAL
ex-
ample shown here.
Flashing alarms are not
to be confused with
‘blinking’ menu items
that may be selected and
edited.
If the 632 has not already been tuned to a signal, the
LOW
SIGNAL
and/or
AUDIO LOSS
alarms will begin to flash soon
— 8 —
after the receiver is turned on. If you press or turn the
knob, you will get a few seconds respite from the flashing
alarm, enough time to navigate to any setup menu. Of
course, once a station has been tuned-in properly the alarm
condition will be reset.
Whenever you are in the ‘edit mode’; that is, you have en-
tered a menu to edit (make a change to) a blinking setup
item, the front-panel flashing alarm is inhibited while that
parameter is being programmed. The edit mode will time
out after 30 seconds if no entry is made.
The rear-panel tally outputs will always be active for the du-
ration of an alarm, even when the front-panel flashing alarm
is temporarily inhibited.
Tuning and Mode Selection
Whenever power is applied to the 632 receiver, a ‘splash
screen’ with the product ID pops up immediately on the
LCD. This reverts in a few seconds to Menu Screen 1.
This is an example of
Menu Screen 1 as it
might appear when the
receiver is first powered-
up and before it has
been programmed.
Push the jog wheel knob and
FREQ
will begin to blink. Now
the receiver may be tuned by rotating the knob. When
tuned to an FM station, a series of bars to the right of
RF
will give a rudimentary display of incoming carrier strength.
FM:S
(stereo),
FM:B
(blended stereo) or
FM:M
(monaural)
transmissions will be verified in the upper, right-hand cor-
ner. (See Page 11 for selecting the FM reception mode.)
If the station is broad-
casting an RDS (Radio
Data System) subcarrier,
call letters decoded
from the station PI code
should appear on the
LCD screen below
FREQ
. In regions where the PI code is not
derived from call letters, the actual PI code will be shown.
Push the knob again and
FM
will begin to blink. Turn the
knob to force the radio into the HD Radio reception mode.
