1. Your Sonim XP3340 Sentinel only performs Lone Worker
Monitoring and Protection when used with a third party
companion service.

If your Lone Worker Monitoring provider has given you with
separate instructions for setup, please follow those in the first instance.

2. If (and only if) your Lone Worker Monitoring provider has directed you to use the Lone Worker Setup application on the phone, please follow the instruction at:
Loneworker Setup

3. You can also find detailed instructions for setup that are specific to your Lone Worker Monitoring Provider online at:
Loneworker Setup

• Upon powering on the phone, wait for 30 seconds for the
  Loneworker Monitoring service to be fully active before placing any
  outgoing GSM calls.

  applications is recommended.

• Only the side red alarm button is active on all screens. Other keys related to Lone Worker Monitoring are active only in the idle screen.
