Operation as a Manual Reset Device (MRD)
Starting/Resetting a Transmitter
The officer should bring the following equipment to a transmitter installation:
Transmitter
Male and female Clips
MRD
Strap holder
Locking tool
Flat-head screwdriver
Calibration of the transmitter
Before any transmitter installation, the transmitter has to be turned-on and calibrated. When the HMRU
is connected, do the following:
1. Stand next to the HMRU to be able to hear the audible confirmation of the calibration.
2. Hold the transmitter in your hand with the 4 metal pins (2 pairs, along the strap) pointing forward.
3. Hold the MRD in your other hand, with the black button pointing toward the end of the strap.
4. Press the MRD down over one of the pairs of metal pins (it does not matter which) with the two
touch points on the MRD matching the pair of metal pins on the transmitter.
5. To turn-on (or reset) the transmitter press the RED ON button down for one second, the red light
turns steadily ON for two (2) seconds.
6. If the transmitter successfully received the reset command the red light, on the MRD, willflashfor
two (2) seconds.
7. Note that if the transmitter has failed to receive the reset command the red light willturnoff after
the initial two (2) seconds of being ON.
8. If the MRD battery is low the red light will immediately flash for two (2) seconds, once the red
button is pressed. (No command is sent to the transmitter).
Place the transmitter on the side on a non-metal tableand wait 30 to 60 seconds, until audible beeps
are heard from the HMRU. These beeps mean that the transmitter has successfully completed its self-
calibration process and is ready to be mounted on the offender.
