This device should not be used at extreme temperatures below 32° F (0° C) or above 100° F (38° C) or especially near fire. If this occurs, the device will need to warm up or cool off for approximately one hour before it is used again. The device can be stored at temperatures from 0° F (-18° C) to 110° F (43° C). Exposure to temperatures outside this range will void the warranty.
The ARP PRS Sport is normally used indoors. It can be used outdoors but should not be exposed to rain, snow, condensing fog, or condensing humidity, and should not be subjected to long-term exposure to direct sunlight.* Main Pulse frequency - 245 pulses per second (PPS)
The signal generated by the ARP PRS Sport consists of a 10 kHz carrier signal (background pulse) that is expressed continuously over a lower frequency main pulse at 245 PPS (Hz). Both main and background pulses have a characteristic RC charge/ discharge spike shape.
The effective frequency of the waveform is 10 kHz, regardless of the PPS setting. When power is delivered to the user during an application, the power output of the ARP PRS Sport will be reduced from its no-load levels in direct proportion to the load impedance presented by the body of the user.
