Issue
The power LED is
not illuminated
The GSM LED is
not illuminated
Powertxt® hasn’t
responded to my
command
Powertxt® won’t
respond to any
commands
I have received a
reply with ‘incorrect
parameters or invalid
format’
Possible Reason
Powertxt® has no mains power supply
Powertxt® can’t find a network signal
or the SIM card can’t be identified
As Powertxt® needs the mobile network
to operate very infrequently messages
can be lost or not delivered
1. The mobile signal strength in the area is
not strong enough for this device to work
2. There is no mains power available in the
area where Powertxt® is located
3. The SIM is not activated or live
4. An incorrect command is being sent
5. The mobile (GSM) network is down in the
area where Powertxt® is located
The command you have entered is not in the
right format or the command does not exist
Solution
1. Check that mains power is available on the required connection
2. Check the device is fully inserted into the mains power socket/supply
1. Check the SIM card is inserted correctly & wipe clean the gold contacts
on the back of the SIM card
2. Check the SIM card is activated and live (making sure no PIN code is
active on the SIM itself)
Note – Occasionally you can get faulty SIM cards, check with your SIM
provider
If Powertxt® has received the message/command then the required action
will have been carried out however the return/reply message may have
been lost or not delivered. In this case please either a) send a status
request command and this will show you the status of Powertxt® and
whether it has actioned your command or b) wait at least 2/3 minutes and
try the command again
1. Try a different mobile network provider or try Powertxt® in a different
location
2. Check that mains power is available on the required connection
3. Check the SIM is activated and live
4. Check the command is correct and try again (refer to the user manual)
5. Check with your operator regarding coverage in that area
