a flashing “X”. When this happens, please change the battery immediately!  To retain the time during 
a battery change, be sure to first plug the unit into a 12 volt power source.

See the “Menu Options” section of the manual for other Clock controls and options.

Odometer Mode:

Your 

ALFA-Club

 contains dual odometers.  In the Odometer Mode, your display shows these two 

odometers on the left side of the display, and displays the Time of Day in the upper right corner.  The 
odometer is fully factor correctable (6 digit factor) like all other 

ALFA

 odometer products, and may be 

setup to display miles or kilometers.  

In Odometer Mode, pressing the HOLD button will alternately freeze and release the time and 
distance on the display.  These continue to progress unseen, and the up to date values are displayed 
as soon as the Hold is released.  (The Speed readout continues to update even during HOLD.) The 
word “HOLD” appears in the lower right corner to remind you that the display is frozen.  

The 

  

 switch controls the direction of the odometer.  Pressing the 

  

 switch upward causes the 

odometer to run forward, pressing it downward once parks the odometer (odometer off) and 
downward again runs the odometer in reverse.  Note that the shape of the decimal point in the 
odometer display indicates the direction of the odometer.  

The lower right corner of the display contains the battery condition when in Odometer Mode.  The 
indications are the same as in the Clock Mode.

See the “Menu Options” section of the manual for other Odometer controls and options.

Clearing:

Moving the center switch downward activates the Clear function.  In Clock Mode, the Clear function 
will erase all of the memorized splits.  In Odometer Mode, the Clear function resets the second 
odometer (incremental distance) to zero.

Setup Options:

The final 

ALFA-Club

 mode is the Setup Mode.  This is where you set the clock, odometer factor, and 

other operating features of the device.  At any time during the setting of values or options, you may 
move the switch to the SETUP position to abort and access the standard Clock or Odometer modes.

Whenever a menu appears, you will be asked to make a selection using the 

  

 switch.  To select the

option on the top line of the display, press the 

  

 switch upward, and to select the option on the 

lower line of the display press the 

  

 switch downward.  For menus requiring that you enter a value, 

the HOLD button will serve to enter the value.
