Compatibility

For more information about wireless compatibility, see the PASCO website at:

www.pasco.com/compatibility

See Appendix B for more information about the PS-3500 Adapter and Mac OS X models.

Initial Step: Charge the Battery

Connect the Cable

: Use the Micro USB Cable to 

connect the micro USB port on the side of the sensor 
to a USB 

port

 or USB 

charger

 such as the PASCO 

PS-2575 USB Single Port Charger. Charging begins 
automatically. The charger circuit inside the sensor 
turns itself off when the unit is fully charged. The 
battery status LED will shine yellow as the battery is 
charging, and will shine green when the battery is 
charged. The battery is partially charged at the 
factory. Initial charging time may be three hours or 
longer depending on the power source and the 
condition of the battery. 

ON/OFF Information

To turn the sensor on, press the ON button. The status 
LEDs will blink. To turn the sensor off, press and 

hold

 the ON button for a moment until the status LEDs stop 

blinking. The sensor puts itself to sleep after one hour of inactivity if connected, and after several minutes if not 
connected.
