Common questions about manuals, registration, and support for this brand.
No. Connecting locomotives without a digital decoder to the Z21 Digital System can result in high-frequency noise and damage to the motors. Analogue models must be refitted with a suitable decoder before use.
Press and hold the button on the Z21 Digital Centre until the LED flashes violet (approximately 8 seconds). This will return the device to its factory default settings.
Use only the supplied AC adaptor (e.g., Art. No. 10851) with a DC output. Do not connect analogue wound-core transformers or other digital systems in parallel, as this can destroy the Z21 Digital Centre.
Connect your smartphone or tablet to the Z21 WLAN router. Open the Z21 Mobile App, which should automatically detect the control center if connected to the correct network.
