Test Mode (TK-860G Only)

Test Mode Operating Features
This transceiver has a test mode.  To enter test mode,
press [SCN] key and turn power on.  Hold [SCN] key un-
til test channel No. and test signalling No. appears on
LCD.
  Test mode can be inhibited by programming.  To exit
test mode, switch the power on again.  The following func-
tions are available in test mode.
• Controls
[PTT] Used when making a transmission.
[MON] Monitor on and off.
[SCN] Sets to the tuning mode.
[A] Function on.
[D/A] RF power high and low.
[
] Changes signalling.
[
] Changes wide and narrow
[CH
/] Changes channel.
[Volume
/] Volume up/down.
• LCD indicator
"SCN" Unused.
"AUX" Lights at RF power low.
"MON" Lights at monitor on.
"Right side dot" Lights at narrow.
• LED indicator
Red LED Lights during transmission.
Green LED Lights when there is a carrier.

Frequency and Signalling
The set has been adjusted for the frequencies shown in
the following table.  When required, re-adjust them follow-
ing the adjustment procedure to obtain the frequencies you
want in actual operation.

• Preparations for tuning the transceiver
Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is turned, the unit must be
connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
4Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.
• Transceiver tuning
(To place transceiver in tuning mode)
Channel appears on LCD.  Set channel according to tun-
ing requirements.

adjust tuning requirements (1 to 256 appears on LCD).
Use [
] button to select the adjustment item through
tuning modes.  Use [A] button to adjust 3-point or 5-point
tuning, and use [
] button to switch between wide/narrow.

Note
• Flash memory
The firmware program (User mode, Test mode, Tuning
mode, etc.) and the data programmed by the FPU (KPG-56D)
for the flash memory, is stored in memory.  When parts are
changed, program the data again.
• EEPROM
The tuning data (Deviation, Squelch, etc.) for the
EEPROM, is stored in memory.  When parts are changed,
readjust the transceiver.

Repair Jig
• Chassis
Use jig (Part No. : A10-4010-02) for repairing the TK-
860G/862G. The jig facilitates the voltage check when the
voltage on the component side TX-RX unit is checked during
repairs.
