If you have a question or problem, the troubleshooting table may help. (See Table 3.) If you need
assistance, phone Best Power’s Worldwide Service or your local Best Power office. Please have
the model number and serial number (located on the rear of the unit) available.
If the unit must be returned, Best Power will give you a Return Materials Authorization (RMA)

* If the Patriot Pro II’s battery does not recharge after 24 hours in the 3-beeps/5 minute alarm
state, the alarm changes to 3 beeps/10 seconds, indicating the battery must be replaced.
