• Frequency setting conditions
1. Frequencies are set at normal temperatures (+25±2 °C).
2. Frequencies are set with a printed board that has a ground
pattern attached to the underside of an oscillator.
3. Connect the #1 terminal of the oscillator to the ground that
comes with the oscillator.
• If you require a product with a different frequency, power
supply voltage, frequency control range, etc. to the standard
specifications, please contact us with your enquiries.
• Products with the AFC (Automatic Frequency Control) function
are available. If you require such a product, please contact us.
