Introduction:

Congratulations!  You have just purchased the latest in rally clock technology. The 

ALFA

-

Checkpoint

 

has been the leading rally clock on the market since 1983, and its newest incarnation is the best yet.  
In addition to its function as a multi-split clock with memories, the 

ALFA

-

Club

 now incorporates a Dual

Correctable Odometer as well!   

The 

ALFA-Club

 is a more advanced version of the 

ALFA-Checkpoint

. It provides a 3 times larger 

display area, a more efficient user interface, plus all of the advanced features of the 

ALFA-

Checkpoint

. The 

ALFA-Club

 is perfect for laying out rallies as well working controls and competing.

Power On !

The 

ALFA-Checkpoint

 and 

ALFA-Club

 do not have a power on/off switch!  As soon as you insert the 

battery, or plug in the 12-volt power cord, the unit begins working.  (Without a power switch, it 
becomes impossible to accidentally shut off the clock in the middle of a rally.)  To insert the 9-volt 
battery, slide the battery cover off of the bottom of the 

ALFA

 to expose the battery compartment.  The

battery attaches to the snaps found inside the compartment.  To make sure the battery snaps fit 
snugly (with  a “click”) you may have to occasionally give the snaps a gentle squeeze. 

It is important to use 

only 9-volt 

Alkaline

 

batteries in your 

ALFA

 clock.  (Energizer and Duracell are 

examples of appropriate batteries.)  In normal operation, the battery will last for more than 24 hours of
continuous operation.  This life will vary depending upon the display lighting and other selected 
options.  We suggest a fresh battery for each full day of operation for best results.

(When operating from an external 12-volt power source, the internal battery is used as a backup.)

When the 

ALFA

 first turns on, it will briefly display its serial number, and then will begin normal 

operation in Clock Mode.

Normal Operation:

Your new 

ALFA

 clock has two modes of

operation, “Clock Mode” and “Odometer Mode”. 
Within each mode there are various options
which you may turn on and off.  You may switch
between these two basic modes whenever you
like without effecting either the clock or the
odometer.  

See the “Menu Options” section of this manual
for instructions on changing modes, setting the
clock, and selecting various options.   Refer to
the illustration for the location of all controls,
connections and displays:

1.

The 

LCD

 display shows the user all time, distance and memory information.  It is also used to 

create interactive menus to configure the clock for use.  The display lights up for use at night.
