Operating Instructions
Recording
To record audio:

- Press the RECORD button. The record indicator light will illuminate.
- Speak clearly into the built-in microphone, or use an external microphone connected to the microphone jack.

Voice Activated System (VAS): When VAS is enabled, the recorder will automatically start recording when sound is detected and pause when silence occurs, conserving tape and battery life. Refer to the unit's controls for the VAS switch.
2-Speed Recording: The CX-R122 supports two recording speeds. A slower speed allows for longer recording times on a single cassette, while a faster speed offers better audio fidelity. Select the desired speed using the speed switch.

- Adjust the volume using the volume control dial.
- To stop playback, press the STOP/EJECT button.
Cue/Fast Forward & Review/Rewind: Use the FF/CUE button to fast forward through the tape and the REW/REVIEW button to rewind. During playback, holding these buttons allows for quick review or cueing of audio.
Telephone Recording (Optional Accessory)
The CX-R122 may be used with a compatible telephone pickup accessory (such as the included suction cup telephone pick-up) to record telephone conversations. Follow these steps:
- Mount the suction cup of the telephone pick-up to the earpiece of your telephone handset.
- Plug the pick-up's 3.5mm jack into the microphone (MIC) input jack on the CX-R122.
