There is apparently no specific rule on this, see
Article 3. Electronic Monitoring
3540. Continuous Electronic Monitoring Technology.
3541. Required Functionality of Continuous Electronic Monitoring Devices.
"(a) The continuous electronic monitoring device shall:
(1) Be designed to be worn on the ankle by the parolee. The parole agent, at his or her 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 parolee carrying the monitoring device on his or her 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 parolee 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.
(b) The device shall function 24 hours a day, seven days a week."
A prisoner or parolee can file a petition for writ of habeas corpus to challenge the conditions of confinement.
The undefined grant of discretion to the parole agent is arguably void for vagueness, and it is cruel and unusual to make a person wear something that can cause permanent physical damage.
