4. Starting
4.1. Introduction
The best way to learn to use Microgate’s REI2 stopwatch is to begin trying. Bear in mind that there
is no sequence of keys which can damage your stopwatch. However, make sure you read this
manual carefully before connecting any accessories.
This chapter will guide you step by step in the operations to be carried out when starting to use your
REI2.
4.2. First switching on
Start by connecting the mains power supply to the Supply connector, wait a few seconds and switch
on the device.
In the initial screen display the firmware release and language appear for a few seconds. In this case
you will see 1.07.9 followed by 0 or 1 indicating the battery type. 1 indicates longlife batteries
while 0 indicates standard duration.
Note: The request for synchronization does not appear if the internal clock of your REI2 is still
synchronized; the data not valid message does not appear if REI2’s memory contains valid data.
4.2.1. Synchronization
!!! ATTENTION !!!
The system has lost synchronization
A) Synchronize
B) Do not synchronize

The first time REI2 is switched on, its internal clock is
not synchronized. With <F1> select the option

5. Operational philosophy
The various choices possible as regards the various menu choices, the various options and the
various modifiable values are assigned each time to the 5 function keys <F1>…<F5>. All the
operational choices are shown on the bottom line of the display.
There are two possible assignment modes:
1. A function/choice appears above the corresponding function key
2. A letter at the beginning of the line refers to the corresponding function key.
HH:MM:SS.D
A:xxx xxxx xxx xxxxx xxxxx
B:yy yyy yyyyy yyyyy yyy
C:kkkkk kkkkkkk kk
A B C zzzz list
1: Press <F5> to activate this function
2: Press <F3> to activate this choice
The presence or absence of particular choices depends on the function/program activated.
It will often be necessary to insert numerical data (for example, an athlete’s start number) with the
numeric keyboard. The possibility of doing this is indicated by the presence of a cursor (vertical bar
or black square) on the field concerned. After setting the required value, this value can be confirmed
by pressing <ENT>.
The <ALT> key does not have its own function but is used simultaneously with other keys to
modify their behaviour.
The <ESC> key has several functions
• Inside a menu it allows you to return to the previous menu
• During the insertion of a numerical value, it deletes the last figure keyed in and if pressed down
for a long time it deletes the whole field.

6. Synchronization of REI2’s internal clock
REI2 can be synchronized by means of the keyboard, the external line or via radio with the
LinkGate system. If necessary, synchronization can be corrected by putting the internal clock
forward or back.
6.1. Synchronization
Through this function, REI2’s internal clock is synchronized. The operation is performed by
inserting the time of synchronization, confirming each field (hour, minutes, ….) with the <ENT>
key and then the date.
Attention: To be able to carry out synchronization the start line must be’at rest’ when <F4> is
pressed (open for line N/O, closed for line N/C). If the line is not ‘at rest’, the message
‘!!!ATTENTION!!! START line unable to give synchronization impulse………’ will appear.
With:
• <F2> the inserted data can be modified if a mistake has been
• <F4> to confirm synchronization data. With the next start impulse, the internal clock starts
• <F5> to return to the previous menu.
6.2. Modifying synchronization value
In certain situations it may be necessary to change the synchronization of REI2 to align it with other
devices which cannot be resynchronized. After establishing the gap in synchronization between the
two devices (for example with a stop in parallel), insert its value as ‘Time change’ (paying
attention to the alignment; for example, 3 hundredths should be inserted as 300 ten-thousandths).
The date can also be changed. Each value should be confirmed with <ENT>.
The enabled function keys are:
• <F1> Time+ to change the sign of variation, with each press it enables the increase or reduction
of values
• <F3> Correct to change any incorrectly inserted data
• <F4> OK to carry out correction of synchronization
• <F5> menu to quit the function.
6.3. Synchronization verify
Calling up this function makes REI2 ready to receive an impulse from a line (main or LinkPod) or
the LinkGate system
The message SYNCHRONIZATION VERIFY – Wait for impulse… appears on the display.
When REI2 receives an impulse, the channel the impulse comes from and the date and time when it
was acquired are printed on the printed strip.
6.4. Signal
With this function a synchronization impulse for the synchronization of other devices can be
generated. When the function is activated, a request is made for the time and date for generation of
the impulse. Every value must be confirmed with <ENT>.

7. Battery recharge
During normal functioning, the presence of a valid external source of power supply (with a socket
as symbol) or low battery condition (with the symbol of a battery) is shown in the display to the
right of the first line. From the moment the symbol appears, about 90 minutes of autonomy remain.
Recharging of REI2’s internal batteries is managed entirely by the microprocessor. In this way it
has been possible to implement a recharge control which guarantees maximum efficiency of the
batteries at all times, at the same time prolonging their operational life.
When you enter this function, the current state of power supply is shown on the sixth line of the
display as follows:
• ‘Battery use …’ the internal batteries are being used
• ‘Maintenance’ the stopwatch is supplied by the external power source and at the same time the
efficiency of the batteries is maintained by a trickle charge but they are NOT recharged
• ‘Discharge…’ the internal batteries are completely discharged before being subsequently
recharged
• ‘Recharge’ recharge in progress; on the right, the time remaining before the end of recharge is
shown
• ‘Recharge blocked’ recharge has been temporarily interrupted because of insufficient voltage.
It will resume automatically as soon as a voltage level is restored.
To recharge the batteries, connect the plug for recharging to any continuous current supply between
11 and 24 volts. In the REI2 package a special adaptor is provided for mains power supply (220V).
To recharge the batteries or completely discharge them, REI2 must remain switched
on. During recharge it is possible to carry out every kind of timing. The important
thing is not to switch it off.
After a reset the battery gauge cannot calculate the battery status correctly ( ). It
will therefore be necessary to carry out a Charge/Recharge cycle to have accurate
knowledge of battery status.
7.1. Discharge/recharge
When this function is selected, the internal batteries are first completely discharged and then
recharged. This is the most correct procedure for keeping the internal batteries at maximum
efficiency.
The duration of the discharge phase depends on how fully the batteries are charged and can last up
to about 3 hours.
The duration of the subsequent recharge phase is 7 hours for the old type of battery (in version
1.07.9.0), while for the new type (in version 1.07.9.1) it is about 9 hours 15 minutes. At the end of
recharge the message ‘RECHARGE OK!’ appears.
7.2. Immediate recharge
If it is not possible to charge or recharge in the correct way because of lack of time or for any other
reason, it is possible just to recharge. In this way recharge time is reduced but this procedure is not
recommended as it reduces the efficiency of the batteries.
