Oregon Scientific PRYSMA B Projection Clock

Introduction

The Oregon Scientific™ Projection In/Out Thermo Clock is a versatile device combining precise timekeeping, alarm functions, and temperature monitoring. This manual provides step-by-step instructions, technical specifications, and important safety warnings for its use.

Product Overview

LCD Display

The LCD display shows various information including time, indoor/outdoor temperature, and weather forecasts. The focus length for projection is approximately 1.5m to 2m.

Getting Started

Connecting Main Unit to Power Supply

Connect the power cable to the Micro USB jack and plug the power adapter into a suitable power outlet.

Inserting Batteries into Remote Thermo Sensor

Slide the battery compartment cover open and insert two "AAA" batteries, matching the polarity as shown, then replace the cover. Press the RESET button inside the sensor after each battery change.

Placement of the Main Unit

• Place the device as far as possible from computers and microwaves to avoid interference with reception.
• Only use this device indoors in a dry location.
