Realignment - Kenwood TK-8102H Service Manual

OPERATING FEATURES / REALIGNMENT
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
option 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
option 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 sup-
ply 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.

3-1. Preface
The TK-8102H transceiver is programmed using a per-
sonal computer, a programming interface (KPG-46) and pro-
gramming software (KPG-70D).
The programming software can be used with an IBM PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.
