Memory Usage
Displays how much
memory
is used up as:
l
a percentage value (% Full)
It also displays the amount of New Data , since initialization of the current study (example:
4.48KB).
Transmitter
Displays the following information:
l
If the transmitter is ON (transmitting) or OFF (not transmitting).
l
Transmit Profile , according to the profile selected under the Transmitter (configuration) tab

Displays External , Self (detections of the receiver’s own transmitter), and Total numbers for
PPM and HR detections accumulated on the receiver since the study was started.
l
PPM - (Pulse Position Modulation) PPM detections are detections received at 180 kHz,
using VEMCO's traditional Pulse Position Modulation coding technology.
l
HR - (High Residency) HR detections are detections received at 170 kHz using VEMCO's
High Residency coding technology.
Pings
Displays total numbers for both PPM and HR pings accumulated on the receiver since the start
of the study. The number of HR pings since the start of the study is the same as the number of HR
detections, as reported under
