- Check if the connector is correctly connected between SRG-150DN/250DN and
terminals.
- Check if 1.7kHz
±
85Hz can come out from DM1 11
th
pin of T-130 PCB.
- Check if the signal is supplied to SRG-150DN/250DN.
13-5 SIMPLE MODULATION OF MODULATOR
As this equipment is designed to have minimum parts to adjust setting, all modulator other
than the modulator for power supply should be adjusted by manufacturer if required.
13-6 CAUTION
1. In case of checking transmitter unit, please get access to dummy load.
2. In case of separating PCB, please pay attention to static electronic.
3. In case of modulating, please use the exclusive tools for modulation.
4. In case of checking or modulating, when measuring instrument reach each circuit, user
should get the signal of the circuit and PROBE of measuring matched
5. In case of maintenance, please be mindful of the difference of status of equipment
between when measuring instrument is connected into each circuit and when not being
connected.
6. All the maintenance for adjusting setting and improving quality should be conducted by
