Transceiver Setting
When the KGP-2A/2B is connected to a transceiver, the
transceiver functions must be set. The transceiver FPU is
used to make this setting.
For a connection method, see Figure 1.
s TK-*80 Series Setting Method
1. Setting with KPG-49D (K and M markets FPU)
1) Select "Optional Features" from "Edit" on the menu bar
and change Com2 (Internal Port) from "[None]" to "[AUX
Hook/PTT]".
2. Setting with KPG-60D (E markets FPU)
1) Select "Extended Function" from "Edit" on the menu
bar and change Com2 from "[None]" to "[AUX Hook/
PTT]".
s TK-*60G Series Setting Method
Use the KPG-56D as the FPU.
1) Select "Key assignment" from "Edit" on the menu bar,
and set "Foot Switch" to "[None]".
2) Select "Optional Features" from "Edit" on the menu bar
and change "ACC Hook/DTC" from "[ACC Hook]" to
"[DTC]".
Note :
Applicable only for S/No. 302XXXXX or later.
KGP-2A/2B Setting
After programming the transceiver, you need to config-
ure the KGP-2A/2B. Using the FPU (KPG-73D), you can con-
figure the KGP-2A/2B .
Using a cross-wired serial cable (KGP-2A/2B side : D-sub
9- pin female) as shown in Figure 2, plug one connector into
the RS-232C (COM) port of your PC and the other end to the
ACC1 connector on the rear panel of the KGP-2A/2B.
s KGP-2A/2B Setting Method
1) Create a data file using the FPU (KPG-73D).
2) After configuring the KGP-2A/2B to the Programming
Menu mode, upload the data file to the KGP-2A/2B.
For detailed instructions, refer to the Help file included in
the FPU.
To set the KGP-2A/2B in the Programming Menu mode,
refer to "Start the Programming Menu mode" on page 6.

MODIFICATION
Connecting a Separate Microphone for
Emergency Mode (KGP-2A only)
If you apply the modification as described below, you can
connect a separate microphone to the KGP-2A in place of
the transceiver's microphone for Emergency mode. The
base station application software which can send out a cor-
responding command is required for the change of a micro-
phone which operates in the time of emergency transmis-
sion.
s Modification
1. Remove R171 (0
).
2. Remove R172 (0
).
3. Add 0
(R92-0670-05) to the $R17 location.
4. Add 0
(R92-0670-05) to the $R18 location.

CONTROL UNIT
(X53-3980-20)
Component side view
Since 5V DC goes through R55 (56k
) and then it is sup-
plied to the microphone input, an electric condenser-type
microphone can be connected to this terminal.
You can also adjust the microphone sensitivity by chang-
ing the R206 (560
) constant between 330 and approxi-
mately 1k
. The microphone pre-emphasis and IDC are car-
ried out by the DSP IC (IC29).
