5-16 HF SSB Transceiver 9323/9360/9390/9780 Technical Service Manual
Control keypad
If there is a lack of response to button selections, it may be due to the malfunction
of one or more of the sealed membrane switches. To test the switches,
disassemble the control head and disconnect J1 [1 04-02974] and remove the
Display Panel PCB. Connect a meter between each pair of pins as indicated in
Table 5-6. An open circuit should appear if the switch is not operated and
continuity (less than 100 Ω) when the switch is pressed.
