Hi Alex,
Unfortunately this is one of the oddities of the Gyration Remote. In its normal state it will only increment/decrement the volume by 1 step when you push the button. This is a limitation of the device. The arrow keys work the same way moving up/down, left or right one location per button press.
Regarding your will to extend the range, the Gyration product is specified to work “up to 100 feet (30.4 meters)”, as indicated in our literature. During test in an open range environment we always meet and commonly exceed the maximum range specified (100ft or 30.4m).
In office environments many other variable come in to play. Walls, cubicles, normal office equipment, furniture, etc. can and often do effect the radio signal, thus effectively reducing the transmitter range. Even building construction and layout can cause these effects. So basically the general environment and not a particular obstruction is causing the reduction in range. Due to unknown and variable environmental conditions we cannot guarantee that the device will always meet the maximum range specified. You can improve performance by using an USB extension cable and repositioning the receiver to optimize radio performance.
Please let us know if you have any question
