1. HOW TO USE THE CHRONOSPLIT HL 640
Terminology: "Activate“ refers to pushing and holding the button indicated.
If the ChronoSplit is off (LCD display blank), activate START/STOP and SPLIT/LAP simultaneously with SET
and keep them held for 2 – 3 seconds to turn ON. Use the same method to turn OFF (if not to be used for
long periods). If any abnormal operation is encountered, perform a reset of the ChronoSplit in the same way.
All operating parameters (Time-of-Day set, date, etc.) must be reintroduced when a reset is performed.
If the
ChronoSplit will not respond to any button use, open the ChronoSplit and remove and reinsert the battery.
ATTENTION. Make certain you have a real problem with the ChronoSplit before opening the case.
Access to the different timing modes can be seen by using the MODE button. Activate (Hold down) the
MODE button and use the SPLIT/LAP button to scroll through the timing mode options as follows:
T I M E
Sets Time of Day. To set, press the SET button until the Hours segment starts to flash. Adjust the hours with
START/STOP (+) or SPLIT/LAP (-). Press SET to confirm the selection and proceed to the same functions
for minutes and seconds. At the exact moment of correct synchronization, press SET again.
D A T E
Same as for TIME but affects date setting. Confirm with SET.
A U T O S P L I T
Selects
Automatic
Timing Mode with SPLIT functions. This mode is driven by remote
radio signals
from
the transmitters HL 640 - 1 attached to your timing sensors at each timing point (photocells, start gate, etc.. )
(Channel 1 / START - Channel 2 or 3 / INTERMEDIATE - Channel 4 / FINISH - A new timing session is
triggered automatically from any new Channel 1 START signal received by the ChronoSplit. All timing
session must end with a Channel 4 FINISH if you don’t want to be disturbed by other impulses
(intermediates).
A U T O L A P
Selects
Automatic
Timing Mode with LAP functions. This mode is driven by remote
radio signals
from the
transmitters HL 640 - 1 attached to your timing sensors at each timing point (photocells, start gate, etc.. )
(Channel 1 / LAP - Channel 2 or 3 / INTERMEDIATE - Channel 4 / FINISH - A new timing session is
triggered by manually activating the SET and START/STOP buttons. (Note: intermediate times are not
shown on the LCD display but they are memorized for download and review later).
M A N S P L I T
Manual
stopwatch timing mode in SPLIT that takes all timing signals from the ChronoSplit buttons with no
radio connection to remote sensors. Use START to begin timing, SPLIT to effect Intermediate times, and
STOP to finish. RESTART using START. After a STOP, use (hold down) SPLIT to reset the ChronoSplit to
zero and begin a new session.
M A N L A P
Manual
timing mode in LAP that takes all timing signals from the ChronoSplit buttons with no radio
connection to remote sensors. Use START to begin timing, LAP to effect lap timing, STOP to finish. After a
STOP, use LAP to reset the ChronoSplit to zero and begin a new session.

data on the ChronoSplit for viewing any of the recorded timing sessions. FIFO (First-in, First Out)
memory recall. Use START/STOP to recall most recent session times. Use SPLIT/LAP to move to other
timing sessions in memory. The best timing session encountered in the memory of all sessions will feature a
“BEST” in the LCD display. To erase the memory activate SET and START/STOP (the LCD display will
indicate REC -- -- -- --).
