Modem Scheduling
ADS Spider power consumption may be drastically reduced by
scheduling the times during the day when the internal modem is
powered up. The modem consumes approximately 90% of the power
while the unit is in its normal mode (i.e., when the display is blank).
This dramatic improvement in power consumption comes at the cost
of the ability to remotely connect to the Spider. Modem scheduling
lets you customize your application by finding an optimal combination
of remote access times and power consumption.
NOTE: During the scheduled modem OFF times, only remote access
is unavailable. Alarm-initiated text messages and e-mail
transmissions will operate normally.
Modem scheduling is disabled by default (i.e., the modem is always
turned on).
To enable modem scheduling, access the
“
Change Settings

page,
as described in Setting up a Spider for the First Time on page 32.
