When the base unit of DECT is not turned power ON;
The waveforms of LE, SK, SIO, CLK2, RDI, TDO and RSSI indicated in below Figures will be observed around the RF. The
Reset terminal should be 2.5V. When GD001 and the base unit of DECT are not linked, the LED is not turned ON. Confirm that
each waveform can be observed. When LE, SK, and SIO can not be observed, they may not be registered or IC1 is possibly
broken. Connect to a PC and input the following test command from DOS Prompt “REGCMD60 00 00 00 00 10”.(*1) Then
when LE, SK and SIO are not appeared on the display, the IC1 has been broken. If they are appeared, IC1 has no problem.
