3.9Checking Magnetron Heater Voltage

Magnetron heater voltage is formed on the MD Board of the scanner unit, and is preadjusted at the factory for use with any length of signal cable. Therefore no adjust- ment is required. However, check magnetron heater voltage as follows:

1.Turn on the radar and leave it in stand- by.

2.Open the scanner cover.

3.Unfasten two screws to remove the RF section cover.
