Note 1: Contact Summit factory for other frequency settings.

Note 2: Voltage, current and frequency accuracies are only guaranteed for factory-programmed settings. Changing any of these parameters from the

values reflected in the customer specific CSIR code will result in inaccuracies exceeding those specified above.

Note 3: The SMB119 device is not intended to function as a battery pack protector. Battery packs used in conjunction with this device need to provide

adequate internal protection and to comply with the corresponding battery pack specifications.

Note 4: Guaranteed by Design and Characterization – not 100% tested in Production.
