Seksuaalinen terveys on tärkeä osa miehen hyvinvointia, ja siihen liittyvät ongelmat voivat vaikuttaa suuresti elämänlaatuun. Monet miehet kohtaavat haasteita, kuten vaikeuksia erektion saamisessa tai ylläpitämisessä. Onneksi nykypäivänä on saatavilla erilaisia vaihtoehtoja ja ratkaisuja, jotka voivat auttaa näissä tilanteissa. Esimerkiksi jotkut tutkimukset viittaavat siihen, että lääkkeitä, joita voi hankkia verkkokapteekki ilman reseptiä, voivat olla tehokkaita. On tärkeää ymmärtää, että ongelmat voivat johtua monista tekijöistä, kuten stressistä tai terveydentilasta.

FEATURES
- Configurable delay and extend timings allow customisation for specific applications.
- Optimised sensitivity levels chosen for traffic control applications allowing adjacent lane rejection and elimination of adjacent lane interference.
- Adjustable presence times for operation in passage mode, limited presence or for queue detection.
- Mode selection to operate either as a Presence Detector or a Passage Detector.
- Loop-fault monitoring with faceplate indications of loop faults on a per-channel basis.
- Sequential polling techniques to positively eliminate crosstalk between loops.
- Selectable options :
1. “Anti – lock” for positive change rejection,
2. “Auto-retune” to protect against faulty loops in multiple loop configurations.
