m@ DTMF memory operation
© Programming a DTMF code
The transceiver has 5 DTMF memory channels (D1 to D6) for
storage of often-used DTMF codes of up to 30 digits.
@® Push [FUNC] + [(H/L)DTMF] to enter DTIMF memory mode.
@ Rotate [DIAL] to select the desired channel.
@ Push [FUNC] + [©SET] to enter DTMF programming mode.
* Programmed memories can be cleared in this way.
@ Push digit keys to enter the desired DTMF code.
* A maximum of 30 digits can be input.
+ If a digit is mistakenly input, push [MR] then repeat from step @.
® Push [(H/.)DTMF] to input the digits.
© Push [(vFo)CLR] to exit DTMF programming mode.
Transmitting a DTMF code
@ Select the DTMF channel to be transmitted:
'> Push [FUNC] + [(H/L)DTMF] to select DTMF memory mode.
'» Rotate [DIAL] to select the desired DTMF channel.
® Push [(vFo)CLR] to exit.
@ While pushing [PTT] push [(H/L)DTMF] to transmit the pre-
viously selected DTMF channel's contents.

Vv CONVENIENT
Monitoring a DTMF code: While in DTMF memory mode,
push [(H/L)DTMF] to monitor the selected DTMF channel with-
out transmitting it.
Confirming a DTMF code's contents: While in DIMF mem-
ory mode, push the [A]/[V] keys to scroll the displayed digits
6 characters to the right or left, respectively.
© DTMF transmit speed « POWER ON
When slow DTMF transmission speeds are required (such as
for some repeaters) the transceiver's rate of DTMF transmis-
sion can be adjusted.
@While pushing [®SET] push
[POWER] for 0.5 sec. to enter ini- { 41] HT
tial set mode.
@® Push [A] or [V] until "DT" appears
in the display.
@ Rotate [DIAL] to select the desired
transmission speed.
*4 speeds are available: "100" being
the fastest and "500" being the slow-
est. slowest
@ Push [(vFo)CLR] to set the condition and exit initial set
mode.
