TX INHIBIT

You can disable the transmit function to prevent unauthorized individuals from transmitting, or to eliminate the risk of accidentally transmitting by yourself.

Access Menu 1–5–5 (TX INHIBIT) and select “ON”.

•Pressing the PTT switch after switching TX Inhibit ON causes the transceiver to generate an error beep and display “TX INHIBIT!”.

SWITCHING AM/FM MODE (TH-D7A ONLY)

This transceiver allows you to select AM or FM mode to receive on the 118 MHz band. The default is AM.

1Select the 118 MHz band.

2Press [F], [6] to switch between AM and FM.

•The 1 MHz decimal becomes long when AM mode is selected.

ADVANCED INTERCEPT POINT (AIP)

The VHF band is often crowded in urban areas. AIP helps eliminate interference and reduce audio distortion caused by intermodulation. You may use this function when operating on the VHF band. Access Menu 1–5–6 (TH-D7A) or Menu 1–5–8 (TH-D7E) and select “ON”.

Note:

◆This transceiver does not allow you to use the AIP on the UHF band.

◆Switching ON the AIP also affects the VHF sub-band on band B.

SWITCHING TX DEVIATION (TH-D7E ONLY)

This transceiver is capable of switching the VHF band to narrow transmit deviation. Access Menu 1–5–7 (144Tx NARROW) and select “ON”.

Note: When using the VHF band to transmit packets, do not switch the function ON.
