# Match and Use a Pendant

A remote button (pendant) provided by Akuvox can be used to make a call or open the door, particularly for the elderly and children in emergencies.

> [!NOTE]
> Note
> 
> The working distance between the pendant and the indoor monitor is up to 30 meters in buildings.

## What You Should Know

- Akuvox offers two kinds of pendants that support different radio frequencies (RF).
- Only S567(Android 14), C315, C317, C319, R15P, and IT82 support using pendants.
- The S567’s version should be 567.30.114.401.

| **Models** | **Support RF** |
| --- | --- |
| C315 | 869 |
| C317 | 869 |
| C319 | 869 |
| IT82 | 869 |
| R15P | 869/433 |
| S567 | 869 |

In this article, we take C319 as an example.
