5. Points of Interest
- Do not hold the antenna while the PMR3 is being used: this may affect transmission quality.
- Do not attempt to charge non-rechargeable batteries as this may damage both the device and the batteries.
- Your PMR3 has been fully tuned prior to shipment. Do not open the housing or alter the settings.
- The only user-serviceable parts are the batteries.
- Avoid using the device in a dusty, humid or extremely hot or cold environment.
- Turn off your PMR in any place where posted notices instruct you to do so, such as on board an aircraft or in a hospital. Most health care
facilities use equipment that is sensitive to external RF energy, therefore it is recommended not to use your PMR there in order to avoid
electromagnetic interference.
- Use a soft moist cloth to clean your PMR3. Do not use chemical agents as they may harm the housing of the unit and leak inside, causing
permanent damage.
