Hi Tina, Melinda and Smokey, My Mellow Fellow here, Tina, if her Holux is the same as the one I have, there is a switch which turns it on and off. It's easy enough to tell when it is on or off just by the position of the switch. If she has another receiver that has a button, and I don't think that the Holux's had power buttons but I could be wrong about that, then it would be more difficult to tell if the receiver is on or off. The only receiver that I've had so far that had a button was my old Magellin, spelling? which was a serial receiver from a few years back, but both of my bluetooth receivers have both had switches. If you need any more help, just ask. Take care, and be safe out there! Your friends always, Melinda and Smokey My Mellow Fellow and April, now our angel dog. mrauch@xxxxxxxxx -- No virus found in this outgoing message. Checked by AVG.
