I have a lowband HT750 that emits a steady, low-pitched tone as long as the power is on. When you depress any button, the audio just clicks and continues the tone.
I performed the latest firmware upgrade and re-dumped the stored codeplug file back into the radio and no change. I do notice that the clip which captures the ribbon cable is superglued together, indicating tht someone in the past was in here and broke the connector.
Any ideas?
HT750 steady tone

This would be the case if no channels are assigned to the channel selector or when the channel selector is pointing to an unassigned channel, or just a faulty channel selector switch.
You can do the button test to check the switch. You enter the self-test if programming allows you to do so by pressing the second lower button 5 times at power up. Now press and hold this button for a bit over 5 seconds to enter the button test. Now you can push and twist any control and it should give a loud high beep with each change.
The above applies to the HT1250 and likely to the HT750 as well.
