BU (Base Unit) Check
1. Register Regular HS to BU (to be
checked).
2. Press [Talk] key of the Regular HS to
establish link.
Check DSP interface. (*2)
'
Check X tal Frequency.
(13.824000 MHz ±100 Hz)
1. Place Regular HS 15 cm away from a
checked BU.
2. Confirm "RXDATA" waveform of Regular
HS by Oscilloscope.
Please try to vary Regular HS CH from 00
ch to 04 ch to be matched to the BU
dummy CH, then the waveform is verified.
(*6)
—
1. Place Regular HS 15cm away from a
checked BU.
2. Confirm "RXDATA" waveform of the BU by
Oscilloscope. (*7)
When the BU scans TX_CW, RXDATA is
LOW.
—
1. Register Regular HS to BU (to be
checked).
2. Press [Talk] key of the Regular HS to
establish link.
3. Compare the range of the BU (being
checked) with that of the Regular BU.
