7 - 4 - 2 TRANSMITTER
1. Check (A)"through (G) in order with RF voltmeter.
2. When the transmitter output is low, check regulated power supply voltage first, do not turn coil
trimmers.
3. When transmission is normal, RF is present and it is not possible to measure the DC voltage
accurately
with a voltmeter.
