device. Devices usually “wake up” every 10 seconds in Fast mode; therefore,
searching for 11 seconds should find the device. If Wait for devices in slow
mode is selected, the software waits for 121 seconds. The device may be in
Slow mode and will only “wake up” every 2 minutes. If Custom wait time is
selected, enter a wait time in milliseconds in the space provided. Once the
proper mode is chosen, hit the OK button to set the ReSync Time option.

Finding Sleeping Devices
If a known device does not respond when interrogated, the device may be
“sleeping”, and the Resync Time may be set to only wait for devices in fast
mode. By default, the software searches for the device for the time interval
specified in the setup menu. To wake a sleeping device, enter its serial number
in the appropriate space under Find Sleeping Sensors in the main menu, and hit
the Wake button. If the software still does not find the sleeping device,
increase the search time to 121 seconds. If the software fails to find the device
after 121 seconds, check the device for possible battery failure. Using Find
Sleeping Sensors overrides the time interval selected in the setup menu. Note:
Find Sleeping Sensors wakes the device and places it temporarily in Always On
mode which significantly increases power consumption.
