Yaesu FT2DR Operating Instructions Manual page 41

Cautions
y Use the transceiver at the minimum required transmit power level. Doing so prevents the transceiver
from overheating and saves battery power, increasing the operating time.
y Do not continue transmitting for a prolonged period. The transceiver can overheat, resulting in
malfunction or a burn injury.
y If transmission is continued for a long period, the transceiver overheats and the high temperature
protection function is activated. As a result, the transmitting power level is automatically set to Low
Power. If you continue transmitting while the high temperature protection function is active, the
transceiver will be forcibly returned to the receive mode.
y If you touch the transceiver immediately after the high temperature protection function has become
active, you may be burned. Wait for the temperature inside the transceiver to cool sufficiently before
resuming transmission.
y Do not start transmitting without attaching the antenna. The transmitter circuit can be damaged.
Tips
• In FM mode, you can transmit on the 144 MHz and 430 MHz ham radio bands.
• Even while receiving in AM mode, transmit will continue to be in NFM mode when pressing
• The transmit power level may be changed by touching [F MW] followed by [TXPWR] (
46).
Transmit power level settings are different when using the chargeable battery pack, or using the
alkaline battery case.
For more details, see "Turning on the Transceiver" on page 32.
• If is pressed when a frequency other than the amateur ham radio band is selected, an alarm tone
(beep) will be emitted and "ERROR" appears on the LCD, disabling transmission.
• The transceiver may be set to inhibit transmit while receiving a signal. Press and hold
for over one second to activate Set mode, then rotate the DIAL to the setting from [CONFIG] → [2
BCLO], and then select [ON].
