29Basic OperationCommunicationHints• By default, the Auto Step mode is selected such that the frequency step ideal for the receptionfrequency is automatically selected.You can change frequency steps manually using the O knob (See page 28).• If you enter a wrong digit when entering a frequency using numeric keys, you can cancel it bypressing the p switch.• By default, turning the O knob beyond the selected frequency band causes the FT1DR to changethe selected frequency band to another frequency band.To prevent this, press and hold the M key over 1 second to select the Set mode and then select“7 CONFIG” “22 VFO MODE” “BAND”. The FT1DR can display frequencies on the samefrequency band repeatedly even if you turn the O knob beyond the selected frequency band.Performing Communication1 While pressing the p switch, speak into the microphone.When speaking into the microphone, keep it about 5 cm away from your mouth.2 Release the p switch.The FT1DR returns to the Receive mode.Precaution Use the FT1DR at the minimum required transmission power level.Doing so prevents the FT1DR from overheating and saves battery power, increasing the operatingtime. Do not continue transmission for a prolonged period. The FT1DR can overheat, resulting in a failureor burn. If transmission is continued for a long period, the FT1DR overheats and the overheat protectionfunction is activated, As a result, Low Power is automatically selected as the power output level. Iftransmission is continued with the overheat protection function held active, the FT1DR is forciblyreturned to the Receive mode.If you touch the FT1DR immediately after the overheat protection function has become active,you can get burnt. Wait for the temperature inside the FT1DR to drop sufficiently before resumingtransmission. Do not perform transmission without installing the antenna. The transmitter circuit can be damaged.
