updated every 5 seconds. The
“
G

preceding the percentage value

indicates that there is no mobile phone coverage in
the present location, there is no valid SIM card inserted (GSM models
only), or that the cellular phone module inside the Spider is not

normal indication during power-up and immediately following remote
access. It typically lasts less than 60 seconds. If, however, this
display persists, contact ADS Environmental Services.
During Web access using GPRS communication (i.e., remote
access), the display shows:
