Section 3541 - Required Functionality of Continuous Electronic Monitoring Devices

(1) Be designed to be worn on the ankle by the supervised person. The parole agent, at their discretion, may request modifications to the placement of the device as an alternative form of continuous electronic monitoring. The modification request shall be considered for approval by the Director or designee, Division of Adult Parole Operations, on a case-by-case basis. The modifications may include the supervised person carrying the monitoring device on their person at all times (fanny pack, back pack, belt etc.) and must be kept within reach when showering or sleeping. The device may be attached to any object which would enable a non-ambulatory supervised person the ability to move around, i.e., a wheel chair;

(2) Emit a signal as a person is moving or is stationary. The signal shall be capable of being received and tracked across large urban or rural areas, statewide, and be received from within structures, vehicles, and other objects to the degree technically feasible in light of the associated costs and design.
