4. Operating Instructions
4.1. Power On/Off and Volume Control
To power on the device, rotate the top-left knob clockwise. Continue rotating to increase the volume. Rotate counter-clockwise to decrease volume and power off.
4.2. Channel Selection
The Dynascan EU-85 supports 16 channels. Use the channel selector knob (top-right) to choose your desired channel. The device can be programmed to select between 8 automatic search channels and 16 manual search channels.
4.3. Privacy Codes (CTCSS/DCS)

- VOX (Voice Operated Transmission): Allows hands-free transmission when your voice is detected.
- Monitor Function (Squelch): Temporarily disables the squelch to listen for weak signals or monitor a channel without a privacy code.
- Priority Scan: Scans through programmed channels to detect activity.
Refer to the programming software (not included) for detailed configuration of these keys.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Dynascan EU-85.
- Cleaning: Wipe the radio with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the accessory port cover is closed when not in use to prevent dust and moisture ingress.
- Battery Care: To maximize battery life, avoid fully discharging the battery frequently. Recharge the battery when the low battery indicator appears. If storing the radio for an extended period, charge the battery to about 50% and remove it from the radio.
- Storage: Store the radio in a cool, dry place away from direct sunlight and extreme temperatures.
- IP55 Rating: While resistant to dust and splashes, avoid intentionally exposing the radio to heavy rain or submerging it in water. Always ensure the battery cover and accessory port cover are properly sealed.
