I ENTERING THE ADJUSTMENT MODE
q Turn the transceiver's power OFF..
w Connect the JIG cable to the [MIC] jack.
e Push and hold the [SET] and [BAND] keys, and then turn power ON.
NOTE:
Exiting from the adjustment mode when the transciever's power is OFF.
I OPERATING ON THE ADJUSTMENT MODE
• Change the adjustment value
• Verifying the adjustment value
• Forward the adjustment item
• Go back the adjustment item
• Store the adjustment value in the memory
CAUTION:
Need to push the [BAND] key when storing the adjustment value in the memory. Otherwise, the transceiver is not
adjusted properly.
CAUTION!: DO NOT
adjustments are adjusted). Otherwise, the transceiver do not work properly.
