Setup and Installation
1. Prepare the Timer
Before setting the schedule, ensure all black push pins around the dial are in the UP (OFF) position. Each pin represents a 30-minute interval.

2. Set the Current Time
Rotate the entire clock dial clockwise until the green arrow on the dial aligns with the current time of day. The dial is marked with AM/PM indicators to distinguish between morning and evening hours.
3. Program On/Off Times
Push down the black pins corresponding to the desired ON times. For example, if you want a device to be ON from 6:00 AM to 11:00 AM, push down all the pins within that time range. Pins that remain in the UP position indicate OFF times.
4. Set the Operating Mode
On the side of the timer, there is a slide switch. Slide it to the 'TIMER' (clock icon) position to activate the programmed schedule. If you want the device to remain continuously ON, slide the switch to the 'ON' position.

5. Plug in Your Device
Plug the HBN mechanical timer into a standard 2-prong electrical outlet. Then, plug your electrical device (e.g., lamp, fan) into the timer's outlet. Ensure your device is switched to the ON position if it has its own power switch.

Operating Instructions
Once set up, the timer will automatically turn your connected device on and off according to your programmed schedule. The internal clock will continuously advance, activating or deactivating the pins as it passes them.
Space-Saving Design
The compact design of the HBN timer ensures that it does not block the second outlet when plugged into a standard duplex wall receptacle, allowing for continued use of the adjacent outlet.
