SET-UP AND OPERATION
1. Mount the TX91503 at the back of a desk or counter to create a PowerSpot® recharging
zone. For wall mounted applications, use the keyholes on the back of the unit to hang
the TX91503 for recharging devices like closet hung wearables.
2. Plug the DC connector of the power supply into the connector on the TX91503. Plug
the power supply into a 120V outlet.
3. The TX91503 will remain off until one of the following occurs1:
a. An authorized device enters the PowerSpot recharging zone.
b. The button on the unit is pressed to recharge a device with a completely
discharged battery. The unit will activate for 30 minutes from a button press and
then will turn off if an authorized device is not present.
4. When the TX91503 is active and transmitting radio frequency (RF) energy, data is
automatically included in the transmission and can be received and used to authorize
the device.
The status LED indicates the following operating conditions:
