25 2) Entering and Releasing the Adjustment Mode The DJ-C7 does not require a serviceperson to manipulate the components on the printed-circuit board, except the trimmer when adjusting reference frequency and deviation. Most of the adjustments for the transceiver are mode by using the keys on it while the unit is in the adjustment mode. Because the adjustment mode temporarily uses the channels, frequency must be set on each channel before adjustments can be mode. For instructions on how to program the channels, see the “DJ-C7 INSTRUCTION MANUAL” which came with the product. In consideration of the radio environment, the frequency on each channel must be near the value (+/-1MHz) listed in the table below. To enter the adjustment mode, set key lock and press [BAND], [V/M], [SCAN], [V/M], [SCAN], [BAND], and [FUNC] key. “Freq” appears in LCD. When changing the adjustment parameters, press the [SCAN] or [BAND] key. To exit the adjustment mode, press the [MONI] key. Adjustment Points 965; :0+, 6 ;( 9@ 5* 6+ ,9
