There have several HD1 features cause confusion. Now here is the explanation of 4 features in HD1 dual band DMR radio.
BDR
when you tick it on CPS. Your HD1 default dual standby, if you don’t tick it, your radio will show one channel and date. But it is not a big matter, you can short press “#” to switch dual standby or single standby.
ROGER
when you tick it on CPS, your HD1 default roger function is on. End of the launch, when you loosen PTT, you will hear a voice, that is Roger, but it only works in analog mode.
Tail Eliminate Mode
It is 54.7hz. as usual, we only use the default one 54.7hz. the use of the reverse code is very few. So you don’t change it. Tail Eliminate, when you tick it, there will no “pu” sound after the end of receiving when using HD1, they both only work in analog mode.
