off according to a preset sound pattern.

transmitted by several Master ITC's. The field GPS-Receiver appears only when "Master"

or "Standby" is set in the field Type which can be found in menu Configuration under the

link Base station settings. The GPS antenna can be activated by changing the status from

"Disabled" to "Enabled" in the field GPS-Receiver.
