DCU Range Setting
DCU Range Setting is designed in order to create a limited free
movement area. This ensures that Offender stays as close as
possible to his\her premises and the immediate surrounding
area.
Four range settings are available: Short, Medium, Long and
Maximum. To change the DCU range, a central computer
command is required.
In order to set and test the DCU reception range, do the
following:
1. Estimate the offender premises size and decide on the
appropriate range setting for starting the range test.
2. Phone the Monitor Center/Agency personnel and ask
them, first, to select the appropriate range and then to
initiate the range setting test. Once the range setting test
has been initiated by the Monitor Center, the following
occurs:
• The Offender’s telephone rings approximately 2-3
times.
• After the phone stops ringing, the telephone line LED
(right) on the DCU unit flashes for a while and then
returns to its steady state.
• After the telephone line LED on the DCU unit stops
flashing, the middle LED blinks 3 times in quick
