# Signals

Canonical page: https://docs.ovok.com/java-sdk/signals

`ovok.signals()` manages Signals delivery for patients.

Enable Signals for a patient, then list and repair residents whose alerts cannot be delivered. Every method is in the [`SignalsResource` reference](/java-sdk/reference/signals-resource).

```java
JsonNode undeliverable = ovok.signals().undeliverable().list();
```
