2) Adj item: [H.RSS_]→
[H.R.SS_]→[H.R.S.S_]→
[H.R.S.S._]→[H.R.S.S._.]
SSG output:
–80dBm (22.4µV)
(MOD: 1kHz/±3kHz)
[NXDN 1) Adj item: [HRSS]
Very Adjust: [✳✳✳]
Narrow] 2) Adj item: [H.RSS_]→
[H.R.SS_]→[H.R.S.S_]→
[H.R.S.S._]→[H.R.S.S._.]
SSG output:
–80dBm (22.4µV)
(MOD: 1kHz/±1.5kHz)
*8: Because "RSSI at –80dBm adjust" of NXDN Narrow is adjusted by adjusting "RSSI at –80dBm adjust [Analog Narrow]", it is not necessary to
adjust "RSSI at –80dBm adjust" of NXDN Narrow.
