How to Perform a Radio Frequency Scan to Diagnose Interference


Applies to: All Elebia hook models with eMAX remote


When to Perform This Procedure

- Operating range drops significantly (for example, less than 10-20 meters instead of the expected 100 meters).

- Hook responds inconsistently or intermittently, especially with physical barriers between the eMAX and the hook.


Prerequisites

- eMAX remote with sufficient battery charge.

- Spectrum analyzer (optional, for precise diagnosis). If unavailable, use the manual method described below.


Procedure With a Spectrum Analyzer


Step 1 - Configure the spectrum analyzer.

Set the center frequency based on your region and configuration. Example: Europe, Short Range, Channel 1 = 868.95 MHz.

Step 2 - Activate the Carrier Signal Test on the eMAX.

Go to Settings > eMAX > Radio > Frequency. Press the up arrow to activate the Carrier Signal Test (displayed in grey). Press the T button to turn it green, confirming the signal is active. Pressing the up arrow again toggles between modulated signal test and carrier signal test.

Step 3 - Analyze the signal.

Confirm the peak is centered at the selected frequency. If not, adjust the tuning parameter on the eMAX. Observe signal strength at different distances and identify any interfering signals.

Step 4 - Find the best configuration.

If the eMAX signal is affected by interference, try different frequency configurations. Refer to the related article on frequency configuration for available options.


Procedure Without a Spectrum Analyzer (Manual Method)

Available configurations by region (each region supports Short or Long reach, Channels 1 or 2):

- Europe

- USA

- Japan

- Korea

Step 1 - Start with the default frequency for your region (for example, F-8 for Europe) and r-0.

Step 2 - If the hook does not respond, adjust the Reach setting and test other frequencies.

Step 3 - If the issue persists, change the channel. Note: changing the channel requires opening the hook. Keep this as a last resort.


Important: the hook and the eMAX must always be set to the same F and r values.


Troubleshooting

eMAX does not detect the hook: confirm both devices are set to the same F and r values (frequency mismatch).

Very short range (less than 10 meters): interference from nearby devices. Change the frequency or Reach setting.
