Section III 

OPERATING THE INOmini 674 

Hey, why is the screen flashing? 

The INOmini 674 activates alarms for reception problems.  

This is detailed later in this section, but you may encounter 

an alarm shortly after you power-up the unit.  These alarms 

identify the condition, flashing their warning against a red 

background, quite visible even across the room. 
If you have not yet set-

up the unit for use, the 

LOW SIGNAL

 and/or the 

AUDIO LOSS

 alarms will 

begin to flash soon after 

the receiver is powered up.  If you push or turn the knob, 

you  will  get  a  few  seconds’  breather  from  the  flashing,  

enough  time  to  navigate  to  any  of  the  setup  menus.    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  setup  item,  the  

front-panel flashing alarm is inhibited while that parameter 

is  being  programmed.    The  edit  mode  times  out  after  30  

seconds if no change is made. 
The rear-panel tally outputs will always be active for the du-

ration of an alarm, even when front-panel flashing pauses 

temporarily. 

NOTE:

  Do not confuse flashing alarms with ‘blinking’ menu 

callouts, which indicate options for editing. 

Menu Navigation Basics 

By  the  time  you’ve  read  this,  you’ve  probably  already  fig-

ured out the INOmini 674 menu for yourself, being as intui-

tive as it is.  Quite simply: 1) 

turn

 the knob to navigate from 

one menu to the next, 2) 

push

 the knob to enter any menu 

associated with setup, 3) 

turn

 the knob to make a selection 

or to set a value, and then 4) 

push

 again to accept the selec-

— 8 — 

tion  and  lock  it  into  non-volatile  memory,  and  to  be  re-

turned to menu navigation. 
In setup menus, any parameter that can be edited will begin 

blinking when the knob is pushed.  Blinking indicates that a 

different option or value may be selected.  Turn the knob to 

make your choice, and then push once again to transfer that 

selection to memory. 
Each INOmini 674 menu screen will be discussed separately 

and in order, except that the last menu is discussed first, as 

it could hinder your progress. 

Locked Menus

 (Menu Screen 11)

 

To guard against inadvertent menu editing or casual tam-

pering, the very last menu in the sequence lets the user 

lock-out the knob from the editing mode.  If you find that 

when you push the knob you are unable to enter the menu 

to change a setup selec-

tion,  go  all  the  way  to  

Menu Screen 11, shown 

here.  Push the knob and 

the  word 

Menus

  will 

begin blinking.  You can then turn the knob to select 

Men-

us:

 

Unlocked

 and push the knob again to set this selection.  

From there you may navigate back to whichever screen you 

wanted to edit.

 

 

Tuning the Receiver

 (Menu Screen 1)

 

When power is applied to the 674 receiver, a ‘splash screen’ 

with the product ID pops up immediately on the LCD.  With-

in a few seconds this will 

revert to Menu Screen 1, 

shown here.

 

 

Push the knob and 

FREQ

 

will begin to blink.  Tune 

the  receiver  by  turning  the  knob.    A  series  of  bars  to  the  

right  of 

RF

  will  give  a  basic  display  of  incoming  carrier  

strength. 
Once the receiver is tuned, push the knob again.   

FREQ

 will 

stop blinking and the tuned frequency will be transferred 

into non-volatile memory.  This releases the knob to navi-

gate to other menus.
