If your Icom Transceiver won't turn on, there are several potential causes. First, the battery might be exhausted, so try charging or replacing it. Second, the battery polarity might be reversed; double-check that the battery is inserted correctly. Finally, a loose connection of the battery pack could be the issue; ensure the battery terminals are clean and the connection is secure.
What to do if there is no sound from the speaker of Icom IC-T70A?
If you cannot hear any sound from the Icom Transceiver's speaker, first, check the volume level and adjust it to a suitable level. Second, if an external speaker or cloning cable is connected to the [SP] jack, disconnect them to ensure the sound is routed through the transceiver's speaker.
Why is transmitting impossible on my Icom IC-T70A Transceiver?
If the Icom Transceiver is not transmitting, first, ensure that the frequency is set within the 144/440 MHz amateur bands. Second, check if the PTT lock function is activated and, if so, turn it off in the Initial set mode. Lastly, if the heat protection is activated and “Hot” is displayed, allow the transceiver to cool down.
What to do if transmitting using the VOX function is impossible on Icom IC-T70A?
If you are unable to transmit using the VOX function on your Icom Transceiver, it may be because the VOX gain is set to OFF or is too low. Adjust the VOX gain to a suitable level. Alternatively, the microphone gain might be too low, so increase the microphone gain to a suitable level.
Why a program scan does not start on Icom IC-T70A?
If an Icom Transceiver program scan does not start, it might be because the memory mode, Call channel mode, or weather channel mode is selected. Push [V/M/C] repeatedly to select the VFO mode. It could also be due to the same frequency being programmed in the scan edge channels “?A” and “?b.” Program different frequencies in the scan edge channels to resolve this.
Why a memory scan does not start on Icom IC-T70A Transceiver?
If a memory scan does not start on your Icom Transceiver, first ensure that the memory mode is selected by pushing [V/M/C] repeatedly. If the VFO mode or Call channel mode is selected, the memory scan will not start. Also, ensure that two or more memory channels are programmed, as the scan will not start with only one or no memory channels programmed.
