Controls

1. Power Switch - This slide switch turns the counter on and initiates a 2 second test of all the LCD segments.

2. Hold Button - This holds the current display and stops the counter from counting.

3. Calibration - The calibration adjustment opening is located on the front panel of the counter. This allows access to the trimmer capacitor that provides about a 10 PPM adjustment range of the time base oscillator.This is not usually necessary but to do so read a signal of an known frequency before adjusting the trimmer for correct frequency display. If you calibrate at 4.1943 MHz or above then the counter will be more accurate.

1. The distance from which you will be able to receive frequencies will depend upon the type and location of the transmitting antenna, transmitter output power and the frequency in use.
   Some typical distances are:
