9.3 Internet remote control 
After you register the alarm on the www.GSMLink.cz
 web site (see 11), 
you can access your alarm remotely from the internet. Using this access 
you can obtain the status of your car, you can arm, disarm and you can 
also stop the car after it was stolen. It is also possible to view the memory 
of the alarm. Installers can change the settings of the alarm remotely 
using the internet access. 
9.3 Dialing-in remote control 
If enabled by the DIP parameters (see 7), the car alarm can be armed 
and disarmed remotely by dialing in from an authorized phone (TEL1 to 
TEL4). The car alarm will not answer the incoming call, but when it 
recognizes your number, it will change status (Arm or Disarm). 
 Such remote control is free of charge since the phone is not answered. 
Warning – if you dial your car alarm accidentally it can cause 
disarming of the alarm. 
9.5 Phone calls by installed hands free set 
If the optional HF-03 hands free set is installed, it is possible to receive 
and make phone calls via the car alarm. When your car is disarmed and 
ignition key is on, the remote control (RC-40) allows you to operate the 
hands free set. 
Incoming calls – to answer them, press any button on the RC-40 remote 
control. By pressing any button again, the call will be terminated. 
  When armed, all incoming calls are automatically rejected. If the car is 
blocked (by IMO instruction) all calls are automatically answered (it is 
possible to listen and to speak to the car remotely). Automatic call 
answering while you are driving can also be enabled by the HF 
instruction (see 9.2). 
To make a call – you can call up to 4 preprogrammed numbers while you are 
driving. By pressing button A, B, 1 or 2 on the remote control you will dial the 
corresponding number (pre programmed by DIALA to DIAL2, see 6.1)

messages will be sent to all phones (TEL1 to TEL4) and these phones will 
also be called with the siren sound. 
To stop the alarm, disarm the alarm by pressing the B button on the 
remote control or by disarm SMS instruction (DM).
