Kenwood TS-670 Instruction Manual page 17

The RF power control works only in SSB, CW and FM
modes.
NOTES:
1. Before transmitting, be sure to connect an antenna
with a low SWR. The TS-670 is provided with a final
protection circuit to protect the final stage.
2. However, if the antenna terminal is open, a failure
may occur. So never transmit without an antenna.
3. The RF PWR meter does not indicate correctly when
the antenna VSWR is poor.
Keep the VSWR as close to 1:1 as possible.

1. When the DOWN switch is pressed with the VFO set
to 1.000 MHz-1.4999 MHz, the VFO changes to
500 kHz.
2 When the DOWN switch is pressed with the VFO set
to 999.9 kHz or lower, the VFO changes to 53 MHz.
