It is recommended that when in the shop / service area, the Communications Service Monitor be

frequency locked to an external reference (WWVH, GPS, Loran C) so that the high stability local

oscillator may be accurately set to within its ±1 ppm frequency tolerance.

The test equipment should be calibrated on an annual basis to ensure accurate measurements.
