Start up the unit the first time
SIM card
The unit needs a SIM-card that works in the GSM (2G) mobile network.
The size is a mini-SIM card. This card is approximately 25*15 mm. Also the size called micro-SIM can
be used if a mini-SIM adapter is used.
It is important that the pincode function is disabled on the SIM-card. A pincode is often activated by
the network operator. Deactivate the pincode in a mobile telephone. See the manual for the
telephone.
Some prepaid SIM cards has a voice message that is played the first time the SIM-card is used. This
message is blocking all the SMS functions in Ontech GSM 9025 and must be removed. Put the SIM—
card in a mobile phone and make a voice call that is answered and the voice message is removed.
Prepaid SIM-cards can be used. Have in mind that it is only valid for a certain period of time if it is not
used and not refilled. The communication with the unit can also use up all money and then the
Ontech GSM 9025 cannot send any message or alarm. We strongly recommend that you register the
prepaid SIM-card at the network operator´s web site so you can handle the card via Internet.
Connecting the unit and shutting it off
The unit is activated when it is connected to the power adapter or an external power source. The
green LED will blink for approximately 15 seconds before connecting to the GSM network. It will then
show a constant green light. Position the unit so the text on the front is correctly oriented, otherwise
the temperature measurements might be affected.
If the main power source is compromised in any way the internal back up battery will continue to
power the unit. A message will be sent after 1 minute to all the registered mobile phone numbers on
the alarm list with information that the main power has failed (See Power fail alarms on page 23). To
turn the unit off, simply disconnect the unit from the main power source and hold down the main
button on the unit for approximately 30 seconds.
Installing the unit
1. Connect the antenna to the unit.
2. Place the unit where you want to install it and attach it with two screws in the lower screw
holes. The antenna should be facing down.
3. Open the unit by unplugging the two screws that is positioned on the sides of the bottom of
the unit.
4. Carefully pull off the “plastic hood” from the unit to be able to reach the SIM- card holder. Be
careful when pulling the shell off because there is a possible risk that the flat cable might lose
its attachment.
