Attenuation of a wireless signal, particularly a short range wireless pairing signal, is accommodated immediately and automatically by a device in response to detection of presence of an object. When a user provides input to the device, such as by touching the device with a finger, presence of the finger may interfere with a signal emitted from the device. To accommodate for such interference, the device may immediately increase its transmission power upon detection of the finger, without waiting for link quality measurements.
