* The TS22 Series Test Set contains an embedded 3-volt lithium battery. The 9-volt battery in the Test Set should be changed when low, or once a year if not in use, to prevent the 3-volt battery from draining. A 3-volt battery that drains after its 42-month warranty will need to be replaced by an authorized service facility at a charge to you.
* Note also that your speakerphone will no longer work when your 9-volt battery is low or dead. You should replace the 9-volt battery whenever it is low.
