Tone squelch operation on sub-band may notbe performed correctly during DTCS transmission.• The tone/DTCS code squelch opens sometimes whenother stations communicate using an adjacent tone fre-quency or in a DTCS code.• The tone/DTCS code squelch can be operated on FM orFM-N mode only.85TONE SQUELCH AND POCKET BEEP11
