That knob should just pull straight off. Check to make sure there isn't a tiny set screw on the side, but otherwise you can pull it off and remove the cover plate.

simple remove the plate then there are two screws that you need to unscrew then you pull the whole thing out.

SOURCE: How do I replace batteries in the ST01 series

The Intermatic ST01 uses a CR2 3 Volt-DC battery to operate the "click-clack" ON - OFF function of the timer.

In order to change the battery, simply pull down the flap just below small display screen. This is the manual switch that you can push to turn the timer on and off.

Just use your fingernail at the top of the door flap and pull down, it will open up and reveal another small tab. This is the battery holder/tray.

To open this, either use your fingernail or a small flat bladed screwdriver at the top to slide out the battery holder tray.

If you remjove and replace the battery within 30 seconds or less, you won't have to reprogram the time/day/date/year. Otherwise taking longer you'll have to reset the time and date feature of the timer.

Don't worry, the timer remembers your program ON - OFF cycles regardless of whether the battery is in the timer or not.

Hope you find this Very Helpful and best regards!

By chance did you connect both the incoming and outgoing white (neutral) wires together without also connecting them to the "A" terminal? If so, untwist them and connect both of them under the "A" terminal. The timing motor will not work if the "A" terminal is not connected to a neutral.
With the circuit energized from the breaker, you should be able to read 120 volts from the "A" terminal to the #1 terminal.
Also, check to make sure the yellow dial is pushed in and set to the correct time.
Otherwise the timer is defective and a return to the store is in order.

The wiring for the T101 is as follows:
Connect _both_ the incoming and outgoing neutrals (white) wires to the "A" terminal. The incoming [(LINE) (hot) (from the breaker or source)] black wire is connected to the #1 terminal and the outgoing (LOAD) black wire is connected to the #2 terminal.
Both of the bare or green wires are twisted together along with a 6 inch or so pigtail using a red or yellow wire nut. The pigtail is then connected to the green "GR" screw on the enclosure
