Troubleshooting
Is the PHMU placed 3 to 6 feet off the floor on a stable, nonmetallic surface?
Is the phone line that is attached to the PHMU in good visible working order? We
provide new phone lines with each PHMU; please utilize the phone lines we
provide.
Is the phone line fully inserted into the phone jack & PHMU?
In order to check the PHMU, attach a telephone handset to the spare socket in
the rear of the PHMU…then generate an event by unplugging the unit from both
power and telephone for approx 2 minutes, then reconnect. Pause for 15
seconds and lift the telephone handset. It should be possible to hear the unit
dialing in to report the events.
Wait 5 minutes, then phone the monitoring center and confirm that the events
have been received and confirm the correct equipment serial numbers have
been assigned
Are you cutting the G4S Justice Services fiber optic band with the tools
provided? Please do NOT fit the fiber optic band by cutting with standard
scissors or wire cutters the cut may not be even (might bend the fibers) and
could result in intermittent band tampers.
If enters and leaves occur only at night, review with the participant the possible
causes of interference
Are you confirming proper range by conducting the Range Test?
Troubleshooting Band
Tampering Issues
Band tampering can be checked at the office or in the field by performing the
following sequence of steps:
1. First, remove the PID by cutting the PID Band. Turn the PID over and
inspect the pin barbs through the window. If the pin barbs are broken,
tampering has occurred.
2. Perform a visual inspection for scratches and any other sign of tampering.
Damage to the PID and/or Band are indicators of tamper.
3. Remove the PID Band and check the cut. The cut must be straight for
optimal performance of the light transmissions thru the fiber optics.
4. Check that the optical windows inside the PID housing are clean.
Tip: We recommend a thin cotton swab dipped in rubbing alcohol to clean
the window found inside the PID housing.
NOTE: If participant equipment is replaced, the serial numbers assigned to the participant must be
changed in the Monitoring System.
