SIM Card Missing / SIM Card Fault Error
If during normal operation the unit detects either a missing or faulty SIM card, the
unit will flash the red led four times a second for 10 minutes to indicate the error.
The unit will then automatically reset.
If this error is observed, check that a SIM card is fitted and the SIM card contacts
are clean.
Disclaimers
SMS Limit
This product does not limit the number of messages that can be sent in a given
time period. This should be considered when setting up the unit. For example, if the
measured temperature is likely to fluctuate around the programmed alert level then
you should consider using the alarm delay feature to ensure that you do not receive
notification messages each time an alarm threshold is crossed. Similarly when
you have finished using the unit, remember to use the “Stop monitoring” button
sequence to ensure that the unit will not send any more notification messages.
You can confirm that the unit has stopped and is in Standby mode by pushing the
status button and checking the LEDs.
Failure to adequately configure the product may lead to excessive operating costs.
SMS Delivery
SMS text messaging is a “store and forward” messaging system which uses
message service centres to temporarily store messages until they can be delivered.
When using this product be aware that the text messaging network service does
not guarantee delivery of the messages that are sent to it. Sent messages may
not reach their intended destination and this should be considered when planning
how this product will be used in your application. You should also be aware that
the delay between the unit sending a message and it being received can vary
significantly.
Typical factors that can affect message delivery or timing include:
●
Available credit.
●
Signal strength and quality.
●
Cell tower available capacity.
●
Sending messages between different network operators.
●
Agreements in place between network operators where roaming is used.
●
Available capacity at the sending and receiving message centres.
●
Network outage or planned maintenance.
●
Receiving device switched off, flat battery or nosignal (will eventually
be discarded by the network if they cannot be delivered. The length of time
varies depending on the service provider used).
Warnings
A separation distance of 20cm (7.87”) or more must be maintained between
the antenna of this product and all persons to comply with FCC RF exposure
