User Manual of DM‐5R Two‐way Radio
·CT sign flashing represents that the two-way radio has enter CTCSS scanning state; the numbers of the CTCSS will not move when
there isn't signal;
·After receiving signals, the numbers of the CTCSS move rapidly in turn according to sequence of standard CTCSS. When the
two-way radio finds that the CTCSS in the receiving signals is consistent with one group standard CTCSS, the two-way radio will
issue a "beep" prompt tone, and scanning stops.
·If you want to store this CTCSS scanned, press [MENU] key to store it, otherwise press [EXIT] key to exit.
Relay echo (relay acknowledgement tone)
Relay echo means that, due to the delay of the relay station in its judgment on the loss of carrier signals transmitted by the handset of
the transmitter when the signal transmitted by the handset is retransmitted by the relay station, the relay station is in transmitting state
for a little short time after the handset of the transmitter enters receiving state. Some HAMs just utilize this little short time to judge
whether the relay station has retransmitted our signal.
Via the setting of Menu 30, 31 and 32, this residual signal of the relay station can be caught accurately when returning to receiving
state so as to acknowledge whether our signal has been retransmitted by the relay station.
To do this, Menu 30 and Menu 31 must be set as OFF, and Menu 32 may do the selection between 1 and 10 which can be set as 5
based on the empirical value.
Sound and light alarm/alarm cancellation
In analog mode, enter emergency alarm state by long pressing the alarm function key [CALL]; the system issues alarm sound
continuously, and the bright light flashes at the same time; after pressing the alarm function key [CALL], the system exits from
emergency alarm state and stops issuing alarm sound.
In emergency alarm state, enter PTT transmitting state by pressing [PTT] key (In emergency alarm state, except PTT key and
emergency alarm key, other keys are unavailable) . When there is call incoming, alarm stops, the call can be received normally.
CTCSS/ CDCSS
CTCSS and CDCSS are mainly used to avoid receiving irrelevant calls in the same frequency. If CTCSS/CDCSS is set, only calls for
which the same CTCSS signaling is set in the channel within the effective communication range can be received; but if
CTCSS/CDCSS isn't set, all calls in the same channel within the effective communication range can be received.
You can set the CTCSS/CDCSS signaling of this two-way radio manually via frequency writing software. CTCSS/CDCSS signaling
code can be set as any value within the range of 67.0~254.1/D023~D777 respectively.
