Battery
The tracker contains a lithium ion battery. This battery, when fully charged, should be
enough to run the tracker for months. It is best to keep it well charged.
There are a number of factors which affect battery life, including how much you use the
light, the network signal strength and the wakeup interval. See the SpyLamp section on
the website setup page for more details.
You can see how much battery is left with the command checkbattery
The tracker will stop working at 3.35 volts
You will receive a low voltage warning at 3.5 volts
Approx 4 volts represents a full charge
If the battery is below 3.35 v and you attempt to switch the light on, the light will flicker
and switch back off. It is time to charge the battery. Please use the charger provided.
Responding to text messages
SMS text messages are sometimes not responded to straight away for a number of
reasons :
The tracker will respond to text messages if it is connected to the network.
Using the default settings, the tracker will stay connected to the network for 5 mins after it
wakes up (either from timer, button press or vibration sensor). It will respond to SMS
messages during this time but afterwards will go back to sleep and disconnect from the
network. It does this to maximise the battery.
If an SMS message is sent to the tracker while it is not connected to the network then it
should receive this message the next time it connects.
How this occurs is dependant on your GSM network provider. Most send through missed
text messages within 30 seconds of connecting but sometimes it can takes several
minutes. This varies between networks and current network load.
Sometimes SMS messages are not delivered immediately by the GSM networks. This
may be due to network congestion. Occasionally it can be hours before they arrive,
although this is unusual. If in doubt, just send the message again.
*NB an easy way to ensure the tracker is connected when you want to change its
configuration is to switch the light on and off. Wait 30 seconds to ensure that the
tracker has connected to the network and then send it a text.
Always check you have credit on your SIM card.
Downloading new software
The tracker can download new software from the online web server. This is useful for
upgrading the tracker, fixing issues and making enhancements.
