■SP Unmute

You can select the type of SP Unmute system for each
channel. The selection is as follows.
Carrier, QT/DQT:
Channel with this option will not check ID Code in order to
open its speaker.
Carrier+DTMF, QT/DQT+DTMF:
Channel that is set with this option will have to check for
ID Code in order to open its speaker.
Default:
Carrier, QT/DQT.

■Auto Reset

If option signalling matches a group set up with option sig-
nalling, option signalling is released. After matching option
signalling, option signalling will temporarily reset automati-
cally.

■Stun

If the stun code matches, a predetermined action will oc-
cur. Whether option signalling is activated or not, when stun
matches on any channel, the transceiver will become TX in-
hibited or TX/RX inhibited. While stun is active, if the stun
code + “#” code is received, stun will deactivate.
When stun matches, transpond will function. Alert will
not be output.

7. Audible User Feedback Tones

The transceiver outputs various combinations of tones to
notify the user of the transceiver operating state.
Refer to the help file on the KPG-70D, regarding the func-
tions that are not listed below.

■Stun on tone

When a stun code is received, transpond tone sounds.

■Stun off tone

When a stun release code is received, transpond tone
sounds.

■Group call tone

Sounds when a group call with the correct DTMF option
signalling is received, repeats 7 times. You can select yes or
no in the Alert tone level setting.

■Individual call tone

Sounds when an individual call with the correct DTMF op-
tion signalling is received. You can select yes or no in the
Alert tone level setting.

■Key input error tone

Sounds when a key is pressed but that key cannot be
used. You can select yes or no for the optional feature's
warning tone.

■Transpond tone

Sounds when an individual call with the correct DTMF op-
tion signalling is received. For group calls, only the group
tone will sound, not the transpond tone.

■Pre alert tone

Sounds prior to the TOT TX inhibit activation. If TOT pre
alert is set, the tone sounds at the amount of time pro-
grammed, before the TOT expires (TOT time – TOT pre alert
time = Pre alert tone sounding time). You can select yes or
no for the optional feature’s warning tone.

■Transmit protection

The final FET is protected against heat while transmitting
by making the radio cuts down TX power when the tempera-
ture of the final FET becomes higher than reference. After
that, if the temperature continue to rise, transmission is
stopped. The final FET is also protected against over voltage
by having the radio to check that the voltage of power supply
connected to the radio is not higher than about 17V when the
radio is turned on, otherwise it can not transmit. In both
cases when transmission is stopped, a beep will continue to
sound until the PTT key is released.
