Note 1: if the external power source is cut off during charging, charging will be interrupted and
resumed from the same point it had reached before being interrupted when the power source has
been restored. This represents an extra guarantee of the reliability of the recharge system.
Note 2: during discharging and recharging, Racetime2 becomes slightly but noticeably warm. This
is absolutely normal.
It is also possible to access these functions when the chronometer is on. In this way, you can begin
to recharge the device without interrupting your timing session. To access recharge management,
choose 'A: Recharge batt.' from the third screen display of the main menu.

During discharging, it is possible at any time to go straight

over to charging by pressing F1 (A: Rep. charge/disch.). This
will shorten the time needed for recharging. However, you are
advised not to charge the batteries without first discharging

them as this could cause a reduction in the capacity of the
batteries (memory effect).
At any moment, you can interrupt discharging/recharging by

have a considerable amount of time to finish your work,
nearly two hours without using the printer (but much less if
the printer is used frequently). If it is not possible to quickly

connect the chronometer to an external power source, it might
be better to disconnect the printer (see para. C8.10) in order to
increase remaining autonomous functioning.
Remember that when fully charged the batteries can be used
continuously for approximately 8-9 hours, if the printout of a
time is made every 20 seconds. Length of duration may be
less in particularly harsh climatic conditions or if the batteries
are worn out. It is absolutely normal for battery efficiency to
decline after approximately 500-1000 recharge cycles. If you
notice a significant reduction in the duration of the batteries,
please contact Microgate for replacements
