REVERSING THE PKS SIGNAL POLARITY
The transceiver enters the transmit state if the PKS
terminal is shorted to GND. You can invert the polarity
according to the device to be connected.
1 Press [ADV.] (F) from the Menu screen to open the
Advanced Menu screen.
2 Access Advanced Menu 14, "PKS Polarity Reverse".
3 Press [SELECT] (F4) to allow editing of the parameter
box.
4 Press [-] (F4) or [+] (F5) to select "On".
The default is "Off".
5 Press [ ] (F1).
6 Press [MENU] to exit.
Note:
◆ If the inversion of the PKS signal polarity is disabled, the
transceiver is placed into a transmit state by shorting the PKS pin of
the ACC 2 connector to GND.
◆ If the inversion of the PKS signal polarity is enabled, the transceiver
is placed into a transmit state by applying a voltage of 3 V to 5 V to
the PKS pin of the ACC 2 connector.
CROSSBAND REPEATER
If you have the TM-D710A or TM-D700A (G) transceiver
(K-type) with a 6-pin mini DIN connector, you can
configure the TS-990S transceiver and the TM-D710A
or TM-D700A (G) transceiver as a crossband repeater.
The TM-D710A or TM-D700A (G) transceiver will receive
signals you transmit from another VHF or UHF transceiver
when both transceivers are configured to have the same
frequency. The signal is then routed to the TS-990S
transceiver and retransmitted on the frequency you have
configured for the TS-990S transceiver. Likewise, signals
received on the TS-990S transceiver are routed to the TM-
D710A or TM-D700A (G) transceiver and retransmitted to
the transceiver you have with you, allowing you to hear the
received call in a distant location.
Note:
◆ For the repeater function to operate, the squelch levels of both
transceivers (TS-990S and the TM-D710A or TM-D700A (G)
transceiver) must be adjusted properly so that no background
noise can be heard; the transmission is controlled by monitoring
the squelch status only.
◆ Crossband Repeater can function only on the main band.
◆ Refer to the instruction manual supplied with the TM-D710A or TM-
D700A (G) transceiver for connection, configuration and operation.
◆ This function can be used with the TM-D700A transceiver with the
firmware version G2.0 or later.
PREPARATION
You can connect two transceivers with a DIN 13-pin and
mini DIN 6-pin cable as shown below.

Then, be sure that "On" has been configured for both
Advanced Menus 14, "PKS Polarity Reverse", and 15,
"TX Inhibit While Busy". Refer to "INHIBITING THE
TRANSMISSION DURING BUSY (SQUELCH OPENING)"
and "REVERSING THE PKS SIGNAL POLARITY" for the
configuration methods.
