Adjustment - Kenwood NX-300 Service Manual

NX-300(G)
Note:
• When using the ESN Validation function of NXDN Trunk-
ing, the NXDN ESN number changes when the circuit
board is changed (the number is written on the circuit
board); the NXDN Trunking System cannot be accessed.
Use the KPG-110SM on the NXDN Trunking System side
to reprogram the NXDN ESN number.
• When a new printed circuit board is used, the Kenwood
ESN changes, as does the Transceiver Information dis-
play of the KPG-111D/111DN, but this does not have any
effect on the operation of the transceiver.
• If changing to the original Kenwood ESN and NXDN
ESN, please contact our service center.

■ Preparations for checking/tuning the transceiver
Before attempting to check/tune the transceiver, connect
the unit to a suitable power supply.
Whenever the transmitter is turned on, the unit must be
connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
8Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during checking/tuning.

■ Test mode operation features
This transceiver has a test mode. To enter test mode,

exit test mode, turn the transceiver power OFF. The follow-
ing functions are available in test mode.
