12.3.3.2. Oscillator Calibration Procedure

Perform the manual oscillator calibration in receive mode according to the following steps:

1. For a standard oscillator (PENDULUM), load the frequency word from the radio. For a

high stability oscillator (OCXO), load the frequency and the temperature words from the

radio, or, following oscillator replacement, type the words which appear on the oscillator

package.

2. To start manual calibration in receive mode, press the Start Calibration button. The RSS

sends a message to the radio, which in turn starts receiving on the selected receive

frequency channel.

3. Read the RF counter measurement.

4. Press the Stop Calibration button and compare the measurement result to the Radio

Specifications.

5. If the measurement result does not match the specifications, modify the frequency word

and go back to step 2. (It is not recommended to change the temperature word.)

6. If the measurement result matches the specifications, press the OK button. A message to

load the measured frequency into the radio using the Write Device command appears on

the screen.
