RELAY STATE REPORT
It is possible to obtain a relay state report at any time. This will give you the position of the
relays. To do this you will need to send a text.
#
REL=STATE
#
Please Note:
The unit has a “sim active” function which monitors the activity on the simcard. If it has
been inactive for 6 weeks, it will send an automatic text to a pre-recorded number. This will
then eliminate the problem of your sim getting shut down if they are unused for 3 months.
New SIM cards will need registering before they can be used. Full details of how this is
done can normally be found in the SIM card pack. It will normally require that the SIM card
is inserted into a mobile phone, a number dialled and instructions followed. While the SIM
is in the mobile phone it would be a good time to disable any PIN codes, call diverts, ring
back and disable features such as voicemail and text alerts. Details of how to do this can
be found on the SIM card provider’s web site or by calling their customer services. Please
use one of the following SIM card providers - Vodafone, TMobile, O2 or Orange.
Please Note -
Currently not suitable with the network provider “three”
