BEFORE INSTALLATION
EN
- Decide where to place the SM21, taking into account the length of the antenna and DC supply cable together
with the position on the car of the DC supply source you want to use.
- The antenna is not included in the SM21 box. Check and ensure the compatibility of the SM21 with the
antenna you decide to use. If you are using an active antenna, it is recommended to add a bias-tee to power
it properly.
- In order to prevent and drain of the car's battery, the SM21 is equipped with an automatic sleep mode, which
automatically activate after 30 minutes of no Bluetooth connections between the SM21 and the car or phone.
