The wiring should be done in accordance with local regulations. The use of a maximum 10A fuse is
highly recommended.
Please note:
The person who carries out the installation must have basic knowledge on electricity.
Make sure the power is cut off before any operation!
Initial setup
First, prepare the SIM card by a GSM phone and insert into the SIM holder. (See previous picture!)
SIM preparation: Insert the SIM card into a common GSM phone. In the menu, find and disable the
security function that makes the phone asking for PIN number on star up. Next, type the phone
number that belongs to the SIM card in the ’Own Number’ menu – or similar. (That is only to allow
the control unit to acquire the time from the GSM network during turning on. However, it is not
essential to do, since it can be doing with SMS command later, when the control unit is turned on.)
Now the card is ready to be inserted into the control unit.
Before reinserting the cover, the initial setup is to be done to adapt the RGT-03 to the actual
application.
Jumper JP3 and button S1, S2 and S3 will be used.
1.
Turn power on and wait for displaying the
time/date.
2.
Make JP3 shorted by the supplied
connector.
3.
Scroll the menu up or down with button S1
and S2 to check each parameter. Select the
one you need to change by pressing button
S3. A flashing value will then indicate that
the value is ready to be changed. Now use
button S1 and S2 to alter the value. Press
S3 repeatedly to save the value and return
to the menu. The chart below shows the
menu points, the default values, and the
range of possible adjustment.
