1. Introduction and Overview
This manual provides essential information for the safe and effective operation of your RDINSCOS RD700 Portable Carbon Monoxide Detector. The device is designed to detect carbon monoxide (CO) levels in various environments, offering real-time measurements and alerts to help ensure safety.
Carbon monoxide is a colorless, odorless, and tasteless gas that can be deadly. This detector utilizes a high-accuracy electrochemical sensor to provide precise CO measurements.

2. Safety Information
WARNING: Carbon monoxide (CO) is a highly toxic gas. This detector is a safety device but should not replace proper maintenance of fuel-burning appliances and ventilation systems. Always seek fresh air immediately if the alarm sounds.
Carbon monoxide is produced by incomplete combustion of carbon-based fuels (e.g., gas, gasoline, wood). Its insidious nature makes it difficult to detect without a specialized device. High-concentration exposure can lead to coma and death within minutes.

Symptoms of carbon monoxide poisoning include headache, dizziness, nausea, fatigue, blurred vision, coma, convulsions, organ failure, and even death.

7. Maintenance
7.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or internal components.
7.2 Storage
When not in use for extended periods, store the detector in its provided storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
7.3 Battery Care
To prolong battery life, avoid fully discharging the battery frequently. Recharge the device when the battery indicator shows low power.
8. Troubleshooting
8.1 Device Not Powering On
- Ensure the device is fully charged. Connect it to a power source using the USB-C cable.
- Confirm you are pressing and holding the Power button for a sufficient duration (a few seconds).
8.2 Detector Reads '0' PPM Consistently
- A reading of '0' PPM indicates no detectable carbon monoxide in the current environment. This is the expected reading in safe conditions.
- To verify functionality, you can perform a simple test using a small, controlled source of incomplete combustion, such as smoke from a cigarette or smoldering paper, in a well-ventilated area. Observe if the CO reading increases.

8.3 Alarm Sounds Unexpectedly
- Immediately move to fresh air.
- Check for potential sources of carbon monoxide (e.g., faulty appliances, vehicle exhaust, fireplaces).
- If the alarm persists after moving to a clear area, the device may require recalibration or service.
8.4 Cannot Detect Natural Gas Leaks
Please note that the RDINSCOS RD700 Carbon Monoxide Detector is specifically designed to detect carbon monoxide (CO) only. It cannot detect natural gas (methane) or liquefied petroleum gas (such as propane or butane) leaks.
