In case of getting an error "Clip communication failed", while detecting the handset, please check the output of Smart-Clip power source. For stable Smart-Clip functions the recommended power supply is
10V, 1A.
Some phone models use a data cable for charging. So, as soon as it gets connected to Smart-Clip it starts charging and uses about 500mA, plus Clip requires another 130-150mA.
Also, please ensure that your LPT port is set to EPP mode in BIOS and firewall with antivirus are disabled.
